Is Alzheimer’s treatment of injecting stem cells into the brain a breakthrough or quackery? – Quad-Cities Online

IRVINE, Calif. More than eight years after, as he described it, My brain went ... Whats the word? ... Foggy, Jack Sage said finally, four years after he was diagnosed with Alzheimers disease and two years since he began an innovative and extremely invasive therapy, Sage said he is being flooded by memories that seem new, or, at the very least, feel easier to retrieve.

His daughter, Kate, thought Sage suddenly had begun to open up about his past because he knew his time was growing short.

He should not know who I am at this point, Kate said.

His doctor, Christopher Duma, hopes Jack Sage goes down in history as the one-man turning point in the treatment of Alzheimers disease, while others are skeptical about what Duma has done to Sages brain.

The Alzheimers Association reported that 610,000 Californians 65 or older had the disease in 2016, and it estimated increases to 690,000 by 2020 and 840,000 by 2025.

On a cool recent night, Sage, a fit 82-year-old, sat next to his wife Gloria talking about his children (It is significant that Sage remembers their names James, 46, Kate, 50, and Kelly, 56), recalling when he and Gloria moved into their Newport Beach house (1990), their first date (1979), his years as a labor negotiator and executive (1970s and '60s) and the jack hammering he did in the nickel mines (mid-1950s) in Northern Ontario, Canada.

At this point in his illness, his doctor said he should be having more trouble remembering the mine. Sages series of recollections represent the three main components of long-term memory: semantic (recalling the meaning of words), episodic (recalling autobiographic milestones) and procedural (recalling how to accomplish tasks) prompted a grin from Duma, the brain surgeon who, for $10,000 per treatment and without insurance coverage, cut a hole in the back of Sages head and injected a stem cell serum that had been sucked out of Sages love handles.

Is this the Alzheimers breakthrough the world has been waiting for? Or, is this unproven medical procedure what University of Minnesota bioethicist Leigh Turner calls quackery and flimflam? Is this an unsafe, money-grab being conducted outside the approval process of the Food and Drug Administration preying on the most vulnerable among us?

Turner has written extensively and critically about the Cell Surgical Network (CSN), for which Duma, whose home hospital is Hoag in Newport Beach, is listed as a network physician. The CSN promotes the stem cell revolution, which its literature claims, is an appropriate treatment for people suffering from a variety of inflammatory and degenerative conditions, such as cancer, diabetes, bad knees and hips as well as multiple uses in cosmetic surgery.

You dont just start dumping things into peoples brains, Turner said. People may spend a lot of money and find there is no benefit. He (Duma) is exposing people to serious harm. Fat cells dont belong in peoples brains.

Sage is the first patient in Phase I of a clinical study officially called Intracerebroventricular injection of autologous abdominal fat-derived, non-genetically altered stem cells. Sage was the first Alzheimers patient anywhere to have his own liposuctioned cells injected directly into his brain. He has received eight injections (about two months apart) since November 2014.

Duma quickly offers a qualifier. It is far too early to tell if what he has done to Sage will indeed change the world. He said Sage and, later, 19 other patients have not been harmed by the procedure, and that safety is the only criteria in Phase I. Whether the treatment is effective is a question for Phase II, for which Duma is hoping to attract private funding. Also, he wrote a letter to the national Alzheimers Association asking for $700,000 to continue his work. He was instructed to apply officially later this year. If he gets the grant, the fees for his patients would be waived.

So far, Duma is excited by Sages results. Sages most recent cognition scores have risen from 45 on the 100-point Memory Performance Index in March 2015 to 54 in September 2015. The volume of his hippocampus the memory center of the brain has grown from the fifth percentile before his first treatment to the 28th percentile after his fourth treatment to the 48th percentile after his eighth treatment.

Sages brain isnt his only problem. He has a long history of heart ailments that have required the insertion of 12 stents to keep his arteries open.

You cant make a global conclusion based on one patient, but its a huge turning point, Duma said, with the confidence of someone who probes brains for a living.

Duma is somewhat of a maverick in the medical world, a brain surgeon who regularly shuns a scalpel for the gamma knife, a futuristic laser for removing brain tumors.

Duma realizes he will face opposition to his stem cell/brain injection therapy. But, as in all breakthroughs, someone has to be first.

I could have harmed people, he said. I took an enormous leap.

Duma said he is nearly finished writing a paper about his work that he hopes will be published in a peer-reviewed journal.

Immortal Stem Cells Let Scientists Create an Unlimited Supply of Artificial Blood – ScienceAlert

Researchers have developed a line immortal stem cells that allow them to generate an unlimited supply of artificial red blood cells on demand.

If these artificial blood cells pass clinical trials, they'll be far more efficient for medical use than current red blood cell products, which have to be generated from donor blood - and would be a huge deal for patients with rare blood types, who often struggle to find matching blood donors.

The idea isn't for these immortal stem cells to replace blood donation altogether - when it comes to regular blood transfusions, donated blood still does the trick.

But it's a constant struggle to propagate red blood cells from donor blood. In the UK alone, 1.5 million units of blood need to be collected each year to meet the needs of patients, particularly those with rare blood types of conditions such as sickle-cell disease.

"Globally, there is a need for an alternative red cell product,"said lead researcher Jan Frayne from the University of Bristol in the UK.

"Cultured red blood cells have advantages over donor blood, such as reduced risk of infectious disease transmission."

In the past, researchers had attempted to turn donated stem cells straight into mature red blood cells - a technique that works, but is an incredibly inefficient process.

Each stem cell only makes around 50,000 red blood cells before it dies off, at which point the researchers need a new blood donation.

And while 50,000 might sound like a lot, put that into perspective, a typical bag of blood used in hospitals contains around 1 trillion red blood cells.

To overcome this, the University of Bristol team took a different approach - they turned adult stem cells into the world's first line of immortalised 'erythroid' stem cells -erythroid refers to the process that produces red blood cells.

They've called the cell line Bristol Erythroid Line Adult or BEL-A cells.

To create these 'immortal' cells, they effectively trapped the adult stem cells in an early stage of development, which means they can divide and create red blood cells forever without dying, which avoids the need for repeat donations.

"Previous approaches to producing red blood cells have relied on various sources of stem cells which can only presently produce very limited quantities," said Frayne.

"We have demonstrated a feasible way to sustainably manufacture red cells for clinical use," she told the BBC. "We've grown litres of it."

If immortal stem cells soundfamiliarto you, that's because there's another famous line of immortal stem cells used in labs around the world, known as HeLa, which was taken from the tissue of a woman called Henrietta Lacks without her knowledge.

Lacks was an African American woman who had a cancerous tumour biopsied in 1951,and never knew those cells were turned into the immortal HeLa cell line, which has played a crucial role in key milestones such as the development of the polio vaccine, as well asmajor cancer studies, and continues to be used today.

These BEL-A immortal stem cells, on the other hand, were specifically selected from voluntarily donated blood products with the sole aim of generating adult human blood cells.

If their red blood cell products pass clinical trials, they could prove just as revolutionary and useful as Lacks' cells did.

"Scientists have been working for years on how to manufacture red blood cells to offer an alternative to donated blood to treat patients," Dave Anstee, director of the UK's National Institute of Health Research Blood and Transplant Research Unit in Red Cell products, which collaborated on the research, announced in a press statement.

"The patients who stand to potentially benefit most are those with complex and life-limiting conditions like sickle cell disease and thalassemia, which can require multiple transfusions of well-matched blood."

"The intention is not to replace blood donation but provide specialist treatment for specific patient groups,"he added.

"The first therapeutic use of a cultured red cell product is likely to be for patients with rare blood groups because suitable conventional red blood cell donations can be difficult to source."

The artificial red blood cells still need to undergo clinical trials in humans before we can say for sure that they're safe and effective.

But early safety trials based on previous manufacturing methods will begin by the end of this year. If that goes to plan, the researchers will trial the BEL-A cell products in patients shortly after that.

We'll be watching the progress closely.

The research has been published in Nature Communications.

Pioneering stem cell gene therapy cures infants with bubble baby disease – Medical Xpress

March 28, 2017 by Tiare Dunlap Evangelina Vaccaro (far right), who in 2012 received treatment developed by UCLAs Dr. Donald Kohn for bubble baby disease, with her family before her first day of school. Credit: Courtesy of the Vaccaro family

UCLA researchers have developed a stem cell gene therapy cure for babies born with adenosine deaminase-deficient severe combined immunodeficiency, a rare and life-threatening condition that can be fatal within the first year of life if left untreated.

In a phase 2 clinical trial led by Dr. Donald Kohn of the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA, all nine babies were cured. A 10th trial participant was a teenager at the time of treatment and showed no signs of immune system recovery. Kohn's treatment method, a stem cell gene therapy that safely restores immune systems in babies with the immunodeficiency using the child's own cells, has cured 30 out of 30 babies during the course of several clinical trials.

Adenosine deaminase-deficient severe combined immunodeficiency, also known as ADA-SCID or bubble baby disease, is caused by a genetic mutation that results in the lack of the adenosine deaminase enzyme, which is an important component of the immune system. Without the enzyme, immune cells are not able to fight infections. Children with the disease must remain isolated in clean and germ-free environments to avoid exposure to viruses and bacteria; even a minor cold could prove fatal.

Currently, there are two commonly used treatment options for children with ADA-SCID. They can be injected twice a week with the adenosine deaminase enzymea lifelong process that is very expensive and often does not return the immune system to optimal levels. Some children can receive a bone marrow transplant from a matched donor, such as a sibling, but bone marrow matches are rare and can result in the recipient's body rejecting the transplanted cells.

The researchers used a strategy that corrects the ADA-SCID mutation by genetically modifying each patient's own blood-forming stem cells, which can create all blood cell types. In the trial, blood stem cells removed from each child's bone marrow were corrected in the lab through insertion of the gene responsible for making the adenosine deaminase enzyme. Each child then received a transplant of their own corrected blood stem cells.

The clinical trial ran from 2009 to 2012 and treated 10 children with ADA-SCID and no available matched bone marrow donor. Three children were treated at the National Institutes of Health and seven were treated at UCLA. No children in the trial experienced complications from the treatment. Nine out of ten were babies and they all now have good immune system function and no longer need to be isolated. They are able to live normal lives, play outside, go to school, receive immunizations and, most importantly, heal from common sicknesses such as the cold or an ear infection. The teenager, who was not cured, continues to receive enzyme therapy.

The fact that the nine babies were cured and the teenager was not indicates that the gene therapy for ADA-SCID works best in the youngest patients, before their bodies lose the ability to restore the immune system.

The next step is to seek approval from the Food and Drug Administration for the gene therapy in the hopes that all children with ADA-SCID will be able to benefit from the treatment. Kohn and colleagues have also adapted the stem cell gene therapy approach to treat sickle cell disease and X-linked chronic granulomatous disease, an immunodeficiency disorder commonly referred to as X-linked CGD. Clinical trials providing stem cell gene therapy treatments for both diseases are currently ongoing.

Is Alzheimer’s treatment of injecting stem cells into the brain a breakthrough or quackery? – Corvallis Gazette Times

IRVINE, Calif. More than eight years after he realized something was wrong, after, as he described it, "My brain went ...

"What's the word? ... Foggy," Jack Sage finally said after several seconds of silently coaxing his synapses to fire.

More than eight years after his brain went foggy, four years after he was diagnosed with Alzheimer's disease and two years since he began an innovative and extremely invasive therapy, Sage said he is being flooded by memories that seem new, or, at the very least, feel easier to retrieve. His daughter, Kate, thought Sage had suddenly begun to open up about his past because he knew his time was growing short.

"He should not know who I am at this point," Kate said.

His doctor, Christopher Duma, hopes Jack Sage goes down in history as the one-man turning point in the treatment of Alzheimer's disease, while others are skeptical about what Duma has done to Sage's brain. Everyone agrees that Alzheimer's disease is an exploding problem.

The California Alzheimer's Disease Data Report from 2009 projected a 67 percent increase between 2015 and 2030 in residents in Los Angeles, Orange, Riverside and San Bernardino counties living with Alzheimer's disease up to 498,137. The same report references a study, between 2000 and 2004, in which 58 percent of the deaths among people 65 and older in California were attributed to Alzheimer's disease.

The Alzheimer's Association reported that 610,000 Californians 65 or older had the disease in 2016, and it estimated increases to 690,000 by 2020 and 840,000 by 2025.

On a cool recent night, Sage, a handsome, fit, 82-year-old, sat next to his wife Gloria talking about his children (It is significant that Sage remembers their names James, 46, Kate, 50, and Kelly, 56), recalling when he and Gloria moved into the Newport Beach house with a view of the Pacific Ocean (1990), laughing about their first date at the Bel-Air Country Club (1979), recounting his years as a labor negotiator and executive for Del Monte, Allied Chemical and Continental Airlines (1970s and '60s) and going all the way back to the jack hammering he did in the nickel mines (mid-1950s) in Northern Ontario, Canada.

At this point in his illness, his doctor said he should be having more trouble remembering the perilous tunnels of the Sudbury nickel mine.

"You drill into the granite," Sage said. "You put dynamite in the rock. You dynamite it. Then you shovel out what's left."

And mining, you might say, is what is happening in Jack Sage's brain.

Sage's series of recollections, including his exploits on the golf course in Indian Wells where he has a second home and plays several days a week flashbacks representing the three main components of long-term memory: semantic (recalling the meaning of words), episodic (recalling autobiographic milestones) and procedural (recalling how to accomplish tasks) prompted a grin from Duma, the brain surgeon who, for $10,000 per treatment and without insurance coverage, cut a hole in the back of Sage's head and injected a stem cell serum that had been sucked out of Sage's love handles.

Is this the Alzheimer's breakthrough the world has been waiting for? Or, is this unproven medical procedure what University of Minnesota bioethicist Leigh Turner calls "quackery and flimflam?" Is this an unsafe, money-grab it is being conducted outside the approval process of the Food and Drug Administration preying on the most vulnerable among us?

Turner has written extensively and critically about the Cell Surgical Network (CSN), for which Duma, whose home hospital is Hoag in Newport Beach, is listed as a network physician. The CSN promotes "the stem cell revolution," which its literature claims, is an appropriate treatment for people suffering from a variety of inflammatory and degenerative conditions in other words, for cancer, diabetes, bad knees and hips as well as multiple uses in cosmetic surgery.

"You don't just start dumping things into people's brains," Turner said. "The problem is people may spend a lot of money and find there is no benefit. He (Duma) is exposing people to serious harm. Fat cells don't belong in people's brains."

Sage is the first patient in Phase I of a clinical study officially called "Intracerebroventricular injection of autologous abdominal fat-derived, non-genetically altered stem cells." Sage was the first Alzheimer's patient anywhere to have his own liposuctioned cells injected directly into his brain. He has received eight injections (about two months apart) since November 2014.

Duma quickly offers a qualifier. It is far too early to tell if what he has done to Sage will indeed change the world. He said Sage and, later, 19 other patients have not been harmed by the procedure, and that safety is the only criteria in Phase I. Whether the treatment is effective is a question for Phase II, for which Duma is hoping to attract private funding. Also, he wrote a letter to the national Alzheimer's Association asking for $700,000 to continue his work. He was instructed to apply officially later this year. If he gets the grant, the fees for his patients would be waived.

Early in the process, Duma is excited by Sage's results.

Sage's most recent cognition scores have risen from 45 on the 100-point Memory Performance Index in March 2015 to 54 in September 2015. The volume of his hippocampus the memory center of the brain has grown from the fifth percentile before his first treatment to the 28th percentile after his fourth treatment to the 48th percentile after his eighth treatment.

"My golf game is getting better," said Sage, who, heart permitting, plays several times per week. Sage's brain isn't his only problem. He has a long history of heart ailments that have required the insertion of 12 stents to keep his arteries open.

"You can't make a global conclusion based on one patient, but it's a huge turning point," Duma said with the confidence of someone who probes brains for a living.

Duma is somewhat of a maverick in the medical world, a brain surgeon who regularly shuns a scalpel for the gamma knife, a futuristic laser for removing brain tumors. He is known outside the operating room for playing keyboards in bands that specialize in 1970s-era covers of groups such as Genesis, Yes and Emerson, Lake and Palmer. As a child, he was a classmate of John F. Kennedy Jr. at The Browning School in New York City. "We called him John John," Duma said.

Duma realizes he will face opposition to his stem cell/brain injection therapy. But, as in all breakthroughs, someone has to be first.

"I could have harmed people," he said. "I took an enormous leap."

Alzheimer's patients don't get better.

They get diagnosed, lose their dignity and die.

The speed at which death occurs is the only variable.

In the depressing world of Alzheimer's treatment, Sage and Duma represent equal parts hope and skepticism. The Orange County Register contacted universities and research centers across the country, including Stanford, Harvard, Duke, Florida International, UC Davis, and some of the interview requests were denied while other calls were not returned. Very few medical experts want to talk about the combination of stem cells and Alzheimer's disease, apparently because they know so little about it.

"An Alzheimer's patient improving because of therapy? I'm hopeful it's true. I'm hopeful it's true for all patients," said Joshua Grill, the co-director of the Memory Impairments Neurological Disorders (MIND) institute at UC Irvine. "We are in dire need."

But, Grill continued, "One study does not a revolution make. I've never read anything about this (Duma's work), and I don't know what science is behind it."

Dean Hartley, Director of Science Initiatives at the Alzheimer's Association, knew about Duma's work.

"This is new territory," Hartley said. But with one patient, "No, you cannot say this is a game-changer."

Hartley said many studies fail at the Phase II level, where more and more people are exposed to the therapy.

Still, Hartley said Duma's work is encouraging.

"We want to see things like this happen," Hartley said.

It's not as if Duma is conducting his research in secret. He spoke about his study in public forums twice last year Sept. 28 at the Congress of Neurological Surgeons in San Diego, and Oct. 1 at the International Society for Cellular Therapy in Memphis.

Duma said he is nearly finished writing a paper about his work that he hopes will be published in a peer-reviewed journal.

In 1993, Christopher Duma was working at Good Samaritan Hospital in Los Angeles when he and his colleagues began injecting stem cells into the brains of patients with Parkinson's disease. They were making some progress, he said, but politics intervened. Some of the stem cells they were using came from aborted fetuses. Pressure from anti-abortion groups shut that program down.

Fifteen years later, Duma was assisting plastic surgeon Michael Elam on a face-lift on a Parkinson's patient when Elam said, "We need to talk about stem cells."

Elam introduced Duma to Drs. Mark Berman and Elliot Lander, the founders of the Cell Surgical Network.

Berman and Lander had been separating stem cells from fat by using a centrifuge (which they own the patent for) and injecting them into knees and hips and other places where injuries had occurred. Their work had passed an Institutional Review Board after 1,524 patients were treated with no adverse effects, Berman said.

"If you want to repair an injury," Berman said, "the best tissue is the stem cell."

In 2013, Duma suggested a new target for stem cell therapy: the brain.

Duma, with Berman, Lander and Elam as co-authors, tried to begin a study of brain/stem cell injections. But their first attempt at Institutional Review Board approval was denied because they hadn't done animal testing. So they got Dr. Oleg Kopyov at Cal State Northridge to conduct tests on rats.

With the help of Kopyov's work, Duma got Institutional Review Board approval. They chose not to take the usual next step FDA approval.

The Institutional Review Board "was expecting us to go through the FDA," Lander said. "But there are hundreds of obstructions." The FDA approval process usually takes between eight and 12 years, according to the online journal Medscape.com.

Duma said stem cells present a "quandary" for the FDA because "stem cells are not a drug, and they're not food." Clinics that take stem cells out of the body and put them back in without additives argue that they are exempt from FDA mandates.

"We have been harvesting fat from abdomens and putting them in the brain during brain surgeries since the 1920s," Duma said. "We do it nearly on every case for pituitary tumors, acoustic and skull base tumors and for conditions of spinal fluid leakage ... since the 1920s. If the FDA ruled that harvested autologous fat cannot be used in the brain, then it would change nearly a century of neurosurgical standard of care."

Someday, Duma said he hopes the FDA will recognize his work.

The work can't wait, he said.

In August 2013, Jack Sage staggered into the office of Dr. William Shankle in Newport Beach.

Shankle, a renowned expert in cognitive disease he is the author of the Memory Performance Index that is used around the world diagnosed Sage with two problems: Alzheimer's disease and hydrocephalus (fluid on the brain). Sage needed a shunt in his brain to drain the fluid and relieve the pressure.

So Shankle walked him down the hall (their offices are yards apart on the same floor in the same building) and introduced Sage to Christopher Duma, medical director of Hoag Hospital's Brain Tumor Program, and the surgeon who would put in the shunt.

Duma remembers that first meeting. Sage was in "straight-line cognitive decline," Duma said.

Shankle would not grant an interview about Duma or his treatment. Shankle said he is wary of "hocus pocus about Alzheimer's disease" without saying that Duma has done anything wrong. More than a decade ago, Shankle tried a surgical stem cell therapy on patients. He removed patients' stem-cell-rich omentum, a fatty sheath covering the abdomen, cut open their skulls and stretched the omentum directly on their brain. Four of the six patients he studied had serious complications from the surgery.

The patients improved in cognitive tests, but the surgery was too much for them.

"The method of delivering the treatment was radical (surgical transposition of the greater omentum to the surface of the brain while keeping the blood supply intact)," Shankle wrote in an email. "After showing that it really works, my goal was to never do the surgery again but find a different way of delivering these critical factors less invasively."

Sage was the patient Duma had been waiting for.

"Jack was a man who was doomed," Duma said. "He looked like classic Alzheimer's. He had no ability to follow a train of thought. He was asking and re-asking the same questions. People like Jack are there, but they're not there."

Sage was perfect for Duma for other reasons. He has always been a fitness nut cycling, tennis, golf, skiing and 10K runs were all part of his lifestyle. Kate Sage said he has been ordering salmon and spinach for dinner at restaurants for years.

"Jack is the experimental model," Duma said. "He is the brave one."

During two years of treatments, Sage has either maintained or slightly improved his cognitive health. He had a major heart attack in 2016, making his brain less of a cause for concern than his heart.

Kate said she doesn't know if Duma's treatment is working.

"It's hard for me to say this is miraculous," Kate said.

She said she doesn't worry about his brain as much anymore.

"He's going to drop dead with some kind of a heart thing," she said. "He's not going to lose his memory."

The tragedy of Alzheimer's disease is that it not only steals the history that makes us who we are. It takes our skills, our beliefs, our independence, our ability to love.

So far, Jack Sage is still Jack Sage. Obviously, he doesn't know if he would be the same without Duma's treatments.

"I can tell I'm getting better and better," Sage said. Is that pure optimism? The Placebo Effect?

In January, Jack Sage's driver's license came up for renewal. He said he's able to remember driving directions without problem. He still navigates the route from his home in Newport Beach to his other home in Indian Wells. But, he was required to pass the written test, and Sage feared he wouldn't be able to remember the complex rules of the road.

"I was worried," he said.

But he passed, and his license was extended five years.

His improved memory, he said, sometimes catches him by surprise.

"These memories come up when I don't even think about it," Sage said.

Sometimes, the memories take Sage places he doesn't want to go.

When he worked in the nickel mines in the 1950s, he and his first wife had a son.

"His name was Mark," Sage said, speaking slowly as if the memory was bubbling up from depths he didn't want to consider. "We rented a house with a playroom. My wife went shopping, and I was upstairs ...

" ... I was working on my school work for McMaster University ...

" ... we had a drainage basin inside the house ...

" ... when I got to him, he was gone ... "

Sage stopped talking as if flooded by new emotions over the death of his son.

"We were distraught," he said. "It was tough times for years."

In the murky world of Alzheimer's therapy, Jack Sage is still mining.

Sunrise stem cell clinic behind blindness cases is largely … – Concord Register

U.S. Stem Cell Clinic is in the spotlight after three patients reportedly lost their eyesight following procedures here.

The Sunrise facility offers stem cell treatments for a range of diseases and chronic disorders and yet it has no medical facility license.

Heres what you might not know: It doesnt need one.

The facility falls under a regulatory loophole. Regulators with Floridas Agency for Health Care Administration, which licenses health care facilities like hospitals and rehabilitation clinics, say they have no authority over stem cell operations. Neither does the Florida Department of Health, which only has regulatory power over personnel like licensed doctors and nurses working in these facilities.

Both state agencies say that authority lies with the . Yet even here, guidelines for adipose stem cells (harvested from the clients themselves) are unclear.

The FDA could not discuss whether U.S. Stem Cell has faced or could face a potential investigation, spokeswoman Andrea Fischer said. She said the agency is working on guidelines that will clarify how human cells, tissues and products based on them should be regulated. The agency also been posting consumer warnings for years alerting patients to ask if theyre going to be part of an FDA-regulated clinical study.

We really dont know what standards these [clinics] have to conform to, said Dr. Thomas Albini, an associate professor of clinical ophthalmology at the University of Miamis Bascom Palmer Eye Institute. He recently co-authored a report in the New England Journal of Medicine about the U.S. Stem Cell cases.

If someone were licensed, that license would be on the line, he said.

There were no sanctions against the private, for-profit clinic after three women, in their 70s and 80s, lost their sight in 2015 following procedures where they had fat cells liposuctioned out of their belly area and injected into both of their eyes. The women had macular degeneration, a common disorder which eventually leads to blindness. They each paid $5,000 for the procedure.

Two traveled from out of state, and one came from Floridas west coast. At least two went to U.S. Stem Cell because of clinical trials listed on clinicaltrials.gov, a database managed by the National Institutes of Health, said Albini, who along with a Bascom Palmer colleague treated two of the patients shortly after their clinic visits. Their complications included detached retinas, optic nerve damage and eye hemorrhages.

The clinicaltrials.gov posting now says the study was withdrawn prior to enrollment.

On its website, the Sunrise facility says its team of medical researchers and practitioners can draw stem cells from their clients own fat tissue and reinject them into their bodies. There, the cells regenerative power can beat back medical disorders like Parkinsons, congestive heart failure and rheumatoid arthritis, according to the company.

In a written statement, the company, originally called Bioheart, said neither the clinic nor its affiliate, U.S. Stem Cell Inc., is currently treating eye patients.

Since 2001, our clinics have successfully conducted more than 7,000 stem cell procedures with less than 0.01% adverse reactions reported, the statement said. We are unable to comment further on specific cases due to patient confidentiality or legal confidentiality obligations.

The company declined to produce published papers about its research or any trials it had conducted.

Albini questions whether a true trial ever existed. Typically, participants of a clinical trial dont pay for treatment and continue to be monitored through followup appointments. Neither was the case for the three women who went to U.S. Stem Cell Clinic, Albini said.

He also said no legitimate researcher would do an experimental procedure, with no clinical track record, on both of a patients eyes, risking blindness. These people were way out of their league, he said.

Two of the women sued for negligence, failure to warn, and allegations regarding how the product manufactured from their own bodies was defective. Both settled, and their cases were dismissed. Attorneys for U.S. Stem Cell argued that the cases, as filed, involved medical negligence and, as such, needed to be refiled to conform with state law, according to court records.

Attorney Benjamin Bedard, who handled both dismissal filings, could not be reached for comment.

Albini said the FDA had him speak at a workshop in September regarding its concerns about experimental, unlicensed stem cell clinics.

My understanding is its a billion-dollar industry already, he said. We dont have great treatments for people with these conditions. There are people who want tomorrows medicines today and are willing to pay for it.

Henrietta Lacks’ legacy collision of medicine, ethics and race – nwitimes.com

GARY Immortality comes with a catch. Something may be taken without your say. Even your loved ones wont learn about it until decades later.

So it was for the family of Henrietta Lacks, a poor black tobacco farmer. But theyre making up now.

In 1951, doctors removed cells from Lacks cancer-stricken body without her knowledge or permission. Generations later, those cells continue to be valuable tools in biomedical research.

Bad things happen to good people, so great things can be done, said Veronica Robinson, Lacks great-granddaughter. You can be part of science and see its not all that bad.

Robinson and Shirley Lacks, Henrietta Lacks daughter-in-law, addressed this collision of medicine, ethics, and race Wednesday at Indiana University Northwest. The Lacks family legacy, Robinson said, is not about what happened, but how we overcame it.

With recognition for Henrietta Lacks now coming nationally, Shirley Lacks noted, Henrietta has helped all mankind. Theres not one person who hasnt been touched or doesnt know someone touched by the HeLa cell.

Henrietta Lacks, who died in 1951 at age 31, was the unwitting donor of cells from a cancerous tumor biopsied during treatment for cervical cancer at Baltimores Johns Hopkins Hospital. Of the two samples removed from Lacks cervix, one was healthy tissue, but the other sample was cancerous. Dr. George Otto Gey, a cancer researcher at Johns Hopkins, cultured the cancerous sample into what became known as the HeLa immortal cell line.

HeLa has since been used in the polio vaccine, gene mapping, and in vitro fertilization research benefiting countless numbers of patients.

Although family members did not learn of their matriarchs contribution until 1975, today they are sharing Henrietta Lacks story, which has also been chronicled in the best-selling book The Immortal Life of Henrietta Lacks by Rebecca Skloot. An HBO movie about Lacks starring Oprah Winfrey will air April 22.

Robinson said the Lacks family today has a cordial relationship with Johns Hopkins Hospital, which has not financially compensated the family. Although she feels the family should receive something for Henrietta Lacks, she also believes the world got her best part.

When asked about race, Robinson is convinced that race was a factor in the 1951 medical procedure, while Shirley Lacks believes the issue is not about race per se, but rather about a doctor searching for a cancer cure.

The biggest impact of the Henrietta Lacks story, Robinson noted, has to do with medical ethics and humanity. These people (patients) are somebody who matters, she said. You need to treat them like you want to be treated. You need to tell them exactly what youre doing to them. Give them the right to understand.

The March 22 program concluded this years One Book One Campus One Community reading initiative at IUN. Attending were nursing students, including sophomore Amanda Pogue, who focused on ethics in the Skloot book.

Pogue, from Portage, said, Looking back 50 years ago, people are asking, 'How could they ethically do that?' Looking ahead, what will future generations say about what we do?

Molecule kills elderly cells, reduces signs of aging in mice – Science Magazine

The mouse in the back received a drug to eliminate senescent cells and looks healthier than its scraggly companion.

Peter de Keizer

Even if you arent elderly, your body is home to agents of senilityfrail and damaged cells that age us and promote disease. Now, researchers have developed a molecule that selectively destroys these so-called senescent cells. The compound makes old mice act and appear more youthful, providing hope that it may do the same for us.

Its definitely a landmark advance in the field, says cell and molecular biologist Francis Rodier of the University of Montreal in Canada who wasnt connected to the study. This is the first time that somebody has shown that you can get rid of senescent cells without having any obvious side effects.

As we get older, senescent cells build up in our tissues, where researchers think they contribute to illnesses such as heart disease, arthritis, and diabetes. In the past, scientists have genetically modified mice to dispatch their senescent cells, allowing the rodents to live longer and reducing plaque buildup in their arteries. Such genetic alterations arent practical for people, but researchers have reported at least seven compounds, known as senolytics, that kill senescent cells. A clinical trial is testing two of the drugs in patients with kidney disease, and other trials are in the works.

However, current senolytic compounds, many of which are cancer drugs, come with downsides. They can kill healthy cells or trigger side effects such as a drop in the number of platelets, the cellular chunks that help our blood clot.

Cell biologist Peter de Keizer of Erasmus University Medical Center in Rotterdam, the Netherlands, and colleagues were investigating how senescent cells stay alive when they uncovered a different strategy for attacking them. Senescent cells carry the type of DNA damage that should spur a protective protein, called p53, to put them down. Instead, the researchers found that a different protein, FOXO4, latches onto p53 and prevents it from doing its duty.

To counteract this effect, De Keizer and colleagues designed a molecule, known as a peptide, that carries a shortened version of the segment of FOXO4 that attaches to p53. In a petri dish, this peptide prevented FOXO4 and p53 from hooking up, prompting senescent cells to commit suicide. But it spared healthy cells.

The researchers then injected the molecule into mutant mice that age rapidly. These rodents live about half as long as normal mice, and when they are only a few months old, their fur starts to fall out, their kidneys begin to falter, and they become sluggish. However, the peptide boosted the density of their fur, reversed the kidney damage, and increased the amount of time they could scurry in a running wheel, the scientists report online today in Cell. When the researchers tested the molecule in normal, elderly mice, they saw a similar picture: In addition to helping their kidneys and fur, the molecule also increased their willingness to explore their surroundings.

The paper adds a potentially new way to target senescent cells, says diabetes researcher James Kirkland of the Mayo Clinic in Rochester, Minnesota. He cautions, however, that peptides like the one De Keizer and colleagues developed have their own limitations. The digestive system destroys them, so they can only be delivered through inhalation or an injectionyou cant just swallow a pill, he notes.

Although the molecule did not reduce the number of platelets in either mouse group, killing off large numbers of senescent cells could still trigger a potentially fatal complication sometimes suffered by cancer patients. Moreover, senescent cells foster wound healing, and destroying the cells could impair this ability.

Thats why De Keizer says he and his colleagues plan to move cautiously with their molecule. I dont think you should start treating frail people in their 90s. Instead, he says, they want to determine whether the molecule kills cancer cells, which share some similarities with senescent cells, starting with the brain tumor glioblastoma. If the compound continues to prove safe, they can think about testing the peptide against age-related diseases or even aging itself.
