Neurological Regenerative Medicine Unlocking the Potential of … – SelectScience

Dr. Murdoch is a stem cell biologist with an interest in development and regenerative medicine. After completing post-doctoral training at Yale University, she took the role of Assistant Professor at Eastern Connecticut State University, where her time is split between teaching and researching nervous system development.

As our understanding of stem cells has increased, the possibility of using stem cell therapies to treat disease is on the horizon. Barbara Murdoch, Ph.D., Assistant Professor at Eastern Connecticut State University, is studying stem cells found in the olfactory epithelium (OE) with the aim of finding therapies for neurodegeneration.

Exclusive neurogenic niche: The olfactory epithelium

The OE is one of the few tissues in the body which is known to regenerate neurons, preserving our sense of smell throughout our lives.

Have you ever had the experience where you smell something and the scent evokes a memory from years back in time? asked Dr. Murdoch. This is because not only can the stem cells in the OE divide and differentiate to replace the lost neurons, but they can also recreate the exact same connection in the brain as the neuron they are replacing.

Dr. Murdoch explained how by studying these stem cells, she hoped to elucidate the environment and signaling molecules which restrict them to certain cell fates. The aim of her research is to direct neural stem/progenitor cells to create neurons in vitro. We can transplant neuronal precursor cells which are on their way to make neurons into patients, for example to help them recover after a stroke, said Dr. Murdoch.

Development of the olfactory epithelium approaches

One approach to understanding what dictates cell fate is to investigate the regions enriched for progenitors and determine their local microenvironment. The communication signals forming the microenvironment can be used to drive the production of new neurons from neuronal precursors in vitro. To investigate olfactory development, Dr. Murdoch carries out confocal microscopy using antibodies against numerous cell markers such as nestin, 3-tubulin and GFAP.

I was at a meeting when, just by chance, I came across a representative from Covance (now BioLegend) who had an anti-nestin antibody and was kind enough to give me a sample. When I tried it, it was brilliant in the olfactory epithelium and the brain, said Dr. Murdoch.

Dr. Murdoch published her findings in the 2008 Journal of Neuroscience paper, demonstrating that there were stem cell-like cells in the embryonic OE which are very similar to neural cells in the brain known as radial glia cells. Radial glia are responsible for the production of most if not all neurons in the brain. Previously, it was thought that radial glia cells were restricted to the central nervous system, but Dr. Murdochs research shows that they are also present in the OE, which is part of the peripheral nervous system.

The reason I think this was missed by so many other researchers was that the antibody that was typically used as a marker of neural stem cells, the anti-nestin antibody, worked well in the brain but not very well in the OE, Dr. Murdoch explained. However, the new antibody from BioLegend was targeting a different epitope, allowing it to identify and bind well to nestin expressed in the OE.

Dr. Murdoch described finding effective primary antibodies as a somewhat hit or miss process. Often when Im searching for antibodies, I try to get a sample and test it with the organism and tissue type Im using. When you find antibodies that work, you stick with them. Thats the reason why I stick with the antibodies from BioLegend, as they are so specific time and time again, Dr. Murdoch added.

Future research and application in regenerative medicine approaches

Now an Assistant Professor at Eastern Connecticut State University, Dr. Murdoch is furthering her research by using chick embryos as a model to study how the OE develops.

Were trying to find pockets of progenitor cells and learn what the environmental influences surrounding those cells are in vivo, Dr. Murdoch explained.

This research has implications for regenerative medicine, where the same signals found in vivo can be recreated in vitro to make new neurons from neural precursors, derived either from human embryonic or induced pluripotent stem cells. Future work will aim to construct 3D scaffolds combined with signaling molecules and matrices to affect cell fate, Dr. Murdoch said.

Research such as Dr. Murdochs is contributing to an improved understanding of the signaling cascades found in neurogenic niches. Understanding the factors which decide cell fate and coordinate the generation of complex tissue is an important step in developing stem cell therapies to treat neurodegenerative states, such as Parkinsons disease, traumatic brain injury and stroke.

Dr. Murdochs work is funded by the CSU-AAUP.

Henrietta Lacks And Modern Medicine’s Greatest Unpaid Debt – Huffington Post

On Saturday evening I, along with millions of other people, watched the premiere of Auntie Oprahs film, The Immortal Life of Henrietta Lacks, on HBO. At the beginning of the film, I was nestled in my bed, eating a bowl of popcorn. I knew the premise of the movie and seriously, who doesnt love a good Oprah Winfrey performance (and let me just say, as usual, she delivered). But by the middle of the film, I was no longer lying comfortably, instead I was sitting upright, slightly teary-eyed...and by the end, there was popcorn on the floor and I was standing in front my television, gripping my remote tightly and shaking my head in disbelief. I immediately scrolled through Facebook to see if I was alone, and just as I imagined, I wasnt.

Several people with skin like mine who watched the film felt just like I did. Dont get me wrong, the movie was well done and the acting was superb, but it did something that I wasnt expecting. It evoked emotions that are still somewhat difficult for me to articulate. Simply put, I hurt for Henrietta Lacks and her family.

As I watched the movie, I thought to myself, why didnt I learn more about Henny (Henny because shes now my auntie in my head) in school? From grades 7-12, I attended a health sciences magnet school. In college, I was a biology major. To say I know a little something about HeLa is an understatement, but I honestly dont recall hearing much about the owner of those magical cells. Yes, magical. Black girl magic isnt just a hashtag, you know. But I digress. Like many Black women, Henrietta Lacks was an unknown hero who, thanks to the book and subsequent film about her life, is no longer an obscure entity. However, unlike the three heroines in one of my favorite movies, Hidden Figures, Henriettas story did not have such a happy ending.

Henrietta was diagnosed with cervical cancer and died from the disease at the age of 31. As a result, she left a special legacy and five children whose lives would never be the same. But it wasnt her untimely death that shocked me as that was quite common back in the day. No, it was the blatant disregard for her basic human rights that I found so appalling. To which human right am I referring? Henrietta was not given the right to consent, and even though it was not required at that time, ethically, she should have been asked for the use of her cells.

Picture this. Youre a young woman, lying in a hospital bed, gravely ill and undergoing treatment for a disease you dont fully understand. There are doctors and nurses coming in and out of your room. They are talking to you, smiling at you, and poking you with needles. They spread your legs to take a piece of your cervix so they can figure out how to fix you. Its ok because you trust them. But not one time do they ask you if they can use the cells from your body to learn more about your disease. No one takes the time to explain to you how the use of your cells could possibly benefit others for years to come. And after you pass away, no one consults your grieving family members to obtain permission to continue the use of your cells.

Mrs. Lacks, we need your permission for something. Can we use the cells from your biopsy for research? Theres a possibility that you could help us understand this disease better. You could also be helping others.

I imagine a conversation like that with Henrietta would have sufficed, but that didnt happen. So lets not sugarcoat it. Henriettas cells were stolen. Her cells were taken and used to advance research and medical practices and she went virtually unknown for years. And to make matters worse, her family still has not been properly compensated. Unbelievable, I know. Now, some may wonder whats so great about Henriettas cells anyway. Why does her family deserve anything after all of this time? Well, let me explain.

Henrietta cells, i.e., HeLa, were unique. You may say she was an ordinary woman with extraordinary cells. HeLa cells are an immortalized cell line, meaning the cells can be reproduced infinitely in a lab. Her cells have aided in the advancement of science and modern medicine tremendously. For example, the cells were used to develop the polio vaccine. In addition, they have been instrumental in HIV and cancer research. Oh, but it doesnt stop there. These cells even paved the way for in vitro fertilization, and the list goes on and on. And while I am thankful for the progress Henriettas cells have afforded medical research, the treatment of Blacks as guinea pigs in the past has left a very bitter taste in my mouth.

Real talk. What occurred to Henrietta wasnt an isolated incident. We all know about the Tuskegee Experiment the time scientists used Black men as lab animals to study the effects of Syphilis but I wonder just how many stories like Henriettas and the Tuskegee Experiment are still untold? And why have the contributions of so many Blacks been undervalued or erased from the history books? And lastly, why is health equity still so difficult to attain in 2017. What do I mean by that last question? Well, for example, Black women are still dying from breast and cervical cancers at higher rates than other ethnic/racial groups. The same goes for Black men and prostate cancer. I could go on but you get the point. The fact is, I dont know the answers to these questions, and as a public health professional, I am working everyday to identify solutions. But what I do know is this, modern medicine has a huge unpaid debt. The creditors are the descendants of Mrs. Henrietta Lacks, and I, for one, think its time to pay up.

Lonza US cell therapy plant slapped with FDA warning letter – FiercePharma

Swiss CDMO leader Lonza has had its cell therapy facility in the U.S. slapped with a warning letter after halting some production there two months ago because of sterility problems with a product it was producing for a client.

The company acknowledged the FDA action in its first-quarter earnings report Tuesday, saying that the warning letter was issued Monday for its facility in Walkersville, Maryland. The FDA had concerns about issues including validation and aseptic process simulations, the drugmaker said.

Lonza takes this issue seriously, and has already started to address all issues raised by the FDA, the company said.

Lonza first learned about the issue in December after product end-user notified the FDA of the issue, Lonza spokeswoman Constance Ward said in an email Tuesday. Lonza opened an investigation after confirming the sterility issue. She said the plant halted production of the product in the affected manufacturing area in early February, while also quarantining the inventory it had on hand.

"After inspecting both the customer of the product and the Walkerville operations, the FDA issued Lonza a warning letter that identified issues involving validation, aseptic process simulations, corrective and preventive actions, and environmental monitoring, Ward explained.

She said the company expects to have the problems resolved and FFM media manufacturing back online by mid-2017. The company had already begun a $7.6 million manufacturing upgrade at the facility, which Ward said is slated to be finished in 2018.

While the drugmaker said it expects the latest FDA action to have minimal impact on revenues of its Pharma & Biotech segment, it reported sales in the segment were softer in the first quarter because of the action. Without providing specific numbers, the contract manufacturer Tuesday reported that growth in that segment was driven by demand in mammalian manufacturing, as well as in clinical development and licensing.

This is not the first time that Lonza has faced FDA concerns about its biologics operations in the U.S. An API plant it had in Hopkinton, Massachusetts, was cited in 2011 over a plethora of problems, creating supply problems for a drug it manufactured there at the time for French drugmaker Ipsen. After struggling to get issues resolved, Lonza simply closed the plant and concentrated its biologics work at its extensive site in Visp, Switzerland.

Lonza is preparing to expand its Visp biologics capability further. It will break ground in the second half of the year on a new large-scale biologics production facility that it is building in partnership with Frances Sanofi. The companies announced in February that they would share the cost, and capacity, of a 270 million ($286.3 million) plant at Lonzas site in Visp.

Kelly Osbourne Campaigning to Make Stem Cell Therapy Affordable … – Hollywood.com

Wenn

Singer-turned-TV personality Kelly Osbourne wants to help cure fellow Lyme disease sufferers by making stem cell therapy available for all in the U.S.

Ozzy and Sharon Osbournes daughter contracted the condition after she was bitten by a tick during a party for the rockers 56th birthday back in 2004, when her mother had a reindeer sanctuary installed at their Los Angeles home.

However, Kelly wasnt properly diagnosed until 2014, months after suffering a seizure while filming an episode of E!s Fashion Police show in 2013, when doctors claimed her collapse had been caused by epilepsy.

She did some research into her ailments and discovered she was actually struggling with Lyme disease, and promptly sought out alternative treatment to help her overcome the illness.

I started to actually do the one thing doctors tell you not to do and thats to go online and look it up, she explained on Good Morning America, and all roads pointed to Lyme disease so I found a doctor through my mum.

I went to Frankfurt, Germany, and I did stem cell (therapy) and I got cured, Kelly claimed.

The 32-year-old is lucky to have been in a position to afford the treatment, which involves the transplant of stem cells to heal those damaged by the disease, and now she is looking to get involved in making the therapy more widely available and affordable to others less fortunate.

It sickens me that thats not available to everyone and that you have to be considered lucky or privileged to get that sort of treatment, she said. I want to make sure and I will do anything that I can do to make sure that that treatment is available in this country.

Kelly details her experience with the bacterial infection in her new memoir There Is No F**king Secret: Letters from a Bada** B**ch. She isnt the only celebrity to open up about her struggles with Lyme disease pop star Avril Lavigne, and veteran model Yolanda Hadid and her runway star kids Bella and Anwar Hadid have also been battling the illness.

Foyt recovering from stem cell treatment – Racer

He spent a week in Mexico undergoing stem cell treatments and underwent successful surgery Wednesday on his right foot so they wouldn't have to amputate a toe. But, as you might imagine, A.J. Foyt won't let his latest medical travails alter his 60-year routine.

"I'm feeling a little rough today because I just got home from the hospital but I'll be in Indianapolis next month, so that should make me feel better," said the 82-year-old legend who is fielding three cars for Conor Daly, Carlos Munoz and Zach Veach in the 101st Indy 500. "And we damn sure better run better than we did last weekend."

The original four-time Indianapolis 500 winner's toughness has never been in question as he's defied death on and off the race track for seven decades.

His greatest hits list reads like this:

And since he retired from driving it's not been any easier. He received an artificial left knee in 2006, was in for heart surgery in 2010, was admitted to the hospital while fighting a staph infection in 2012, had his right knee replaced, left hip replaced, and had back surgery performed in 2013.

In 2014, IndyCar's all-time winner underwent successful triple by-pass surgery, then got infected and spent eight days on a ventilator and 10 days in ICU while he fought off sepsis.

Because of all his injuries and arthritis, A.J. has been in constant pain in his legs, feet, ankles, shoulders and back to he was convinced to try stem cell therapy. He spent April 11-19 in Cancun because Mexico can grow the volume of stem cells in the hundreds of millions whereas it's only hundreds of thousands in the USA.

"They told me I should start feeling better in two-and-half to three months," said the man who came to IMS as a rookie in 1958, drove in 35 consecutive Indy 500s and has never missed a month of May since. "And yesterday they thought I might lose a toe but they figured out a way to keep it and straighten it out. They're good people but I'm tired of being cut on.

"They said I needed to be back at the hospital next month to get the stitches out and I told them 'no chance.' I'll get some tweezers and pull 'em out myself because next month I'm booked."

Researchers Invent Stem Cell Capable of Becoming an Entire Embryo – Futurism

A New Type of Stem Cell

While much has been gleaned about the power of stem cells over the last few decades, researchers from the Salk Institute and Peking Universityin China recently found out theres plenty left to discover and invent. Nature, it seems, will always keep you guessing.

In a study published in the journal Cell, the team of researchers revealed they had succeeded in creating a new kind of stem cell thats capable of becoming any type of cell in the human body. Extended pluripotent stem cells or EPS cells are similar to induced pluripotent stem cells(iPS cells), which were invented in 2006.

The key difference between the two is that iPS cells are made from skin cells (called fibroblasts) and EPS cells are made from a combination of skin cells and embryonic stem cells. iPS cells are the hallmark of stem cell research and can be programmed to become any cell in the human body hence the pluripotent part of their name. EPS cells, too, can give rise to any type of cell in the human body, but they can also do something very different something unprecedented, actually: they can create the tissues needed to nourish and grow an embryo.

The discovery of EPS cells provides a potential opportunity for developing a universal method to establish stem cells that have extended developmental potency in mammals, says Jun Wu, one of the studys authors and senior scientist at the Salk Institute, in the organizations news release.

When a human or any mammalian egg gets fertilized, the cells divide up into two task forces: one set is responsible for creating the embryo, and the other set creates the placenta and other supportive tissues needed for the embryo to survive (called extra-embryonic tissues). This happens very early in the reproductive process so early, in fact, that researchers have had a very hard time recreating it in a lab setting.

By culturing and studying both types of cells in action, researchers would not only be able to understand the mechanism that drives it, but hopefully could shed some light on what happens when things go wrong, like in the case of miscarriage.

The researchers at the Salk Institute managed to form a chemical cocktail of four chemicals and a type of growth factor that created a stable environment in which they could culture both types of cells in an immature state. They could then harness the two types of cells for their respective abilities.

What they discovered was that not only were these cells extremely useful for creating chimeras (where two types of animal cells or human and animal cells are mixed to form something new), but were also technically capable of creating and sustaining an entire embryo.At least in theory: while they were able to sustain both human and mouse cells, the ethical considerations of creating a human embryo this way have prevented them from attempting it.

That being said, theres no shortage of applications for this type of stem cell: researchers will be able to use them to model diseases, regenerate tissue, create and trial drug therapies, and study in depth early reproductive processes like implantation. Human-animal chimeras may also help engineer organs for transplant or, you know, give rise to the next superhero.

Are baby, wisdom teeth the next wave in stem cell treatment? – CNN

It's based on experimental research that suggests stem cells extracted from the pulp of these teeth might someday regrow a lost adult tooth or offer other regenerative medicine benefits -- some potentially life-saving.

"So I'll try not to get emotional here, but my husband was diagnosed with acute myeloid leukemia in 2011," said Bassetto, of Naperville, Illinois, head of a sales team at a software company.

In 2012, her husband, James, had a stem cell transplant to restore his bone marrow and renew his blood.

"He was very fortunate. He was one of six kids, and his brother was a perfect match," she said. She noted that her two children, Madeline, 23, and Alex, 19, may not be so lucky if they develop health problems, since they have only each other; the chance of two siblings being a perfect stem cell match is only 25%.

Unfortunately, her husband's stem cell transplant was not successful. He developed graft-versus-host disease, where his brother's donated stem cells attacked his own cells, and he died shortly afterward.

However, she says, the transplant had given him a chance at a longer life.

Last year, when her son saw a dentist for wisdom tooth pain, a brochure for dental stem cell storage caught Bassetto's eye and struck a chord.

"I know stem cells have tremendous health benefits in fighting disease, and there's a lot ways they're used today," she said. "Had my husband had his own cells, potentially, his treatment could have been more successful."

Medical breakthroughs happen all the time, said Bassetto. "Who knows what potential there is 20 years, 40 years down the road, when my son is an adult or an aging adult?

"Almost like a life insurance policy, is how I viewed it," she said.

Some scientists see storing teeth as a worthwhile investment, but others say it's a dead end.

"Research is still mostly in the experimental (preclinical) phase," said Ben Scheven, senior lecturer in oral cell biology in the school of dentistry at the University of Birmingham. Still, he said, "dental stem cells may provide an advantageous cell therapy for repair and regeneration of tissues," someday becoming the basis for reconstructing bone tissue, retinas and even optic neurons.

Dr. Pamela Robey, chief of the craniofacial and skeletal diseases branch of the National Institute of Dental and Craniofacial Research, acknowledges the "promising" studies, but she has a different take on the importance of the cells.

"There are studies with dental pulp cells being used to treat neurological disorders and problems in the eye and other things," Robey said. The research is based on the idea that these cells "secrete factors that encourage local cells to begin the repair process."

"The problem is, these studies have really not been that rigorous," she said, adding that many have been done only in animals and so provide "slim" evidence of benefits. "The science needs a lot more work."

Robey would know. Her laboratory discovered dental stem cells in 2003.

"My fellows, Songtao Shi and Stan Gronthos, did the work in my lab," Robey said. "Songtao Shi is a dentist, and basically he observed that, when you get a cavity, you get what's called 'reparative dentin.' In other words, the tooth is trying to protect itself from that cavity, so it makes a little bit of dentin to kind of plug the hole, so to speak."

Dentin is the innermost hard layer of tooth that lies beneath the enamel. Underneath the dentin is a soft tissue known as pulp, which contains the nerve tissue and blood supply.

Observing dentin perform reparative work, Shi hypothesized that this must mean there's a stem cell within the tooth that's able to activate and make dentin. So if you wanted to grow an adult tooth instead of getting an implant, knowing how to make dentin would be the start of the process, explained Robey.

Pursuing this idea, Shi, Gronthos and the team conducted their first study with wisdom teeth. They discovered that pulp cells in these third molars did indeed make dentin, but the cells found in baby teeth, called SHED (stem cells from human exfoliated deciduous teeth), had slightly different properties.

"The SHED cells seem to make not only dentin but also something that is similar to bone," Robey said. This "dentin osteogenic material" is a little like bone and a little like dentin -- "unusual stuff," she said.

There is a meticulous process for extracting stem cells from the pulp.

"We very carefully remove any soft tissue that's adhering to the tooth. We treat it with disinfectant, because the mouth is not really that clean," Robey said, laughing.

Scientists then use a dental drill to pass the enamel and dentin -- "kind of like opening up a clam," said Robey -- to get to the pulp. "We take the pulp out, and we digest it with an enzyme to release the cells from the matrix of the pulp, and then we put the cells into culture and grow them."

According to Laning, even very small amounts of dental pulp are capable of producing many hundreds of millions of structural stem cells.

Harvesting dental stem cells is not a matter of waiting for the tooth to fall out and then quickly calling your dentist. When a baby tooth falls out, the viability of the pulp is limited if it's not preserved in the proper solution.

American Academy of Pediatric Dentistry President Dr. Jade Miller explained that "it's critical that the nerve tissue in that pulp tissue, the nerve supply and blood supply, still remain intact and alive." Typically, the best baby teeth to harvest are the upper front six or lower front six -- incisors and cuspids, he said.

For a child between 5 and 8 years of age, it's best to extract the tooth when there's about one-third of the root remaining, Miller said: "It really requires some planning, and so parents need to make this decision early on and be prepared and speak with their pediatric dentist about that."

Bassetto found the process easy. All it involved was a phone call to the company recommended by her dentist.

"They offer a service where they grow the cells and save those and also keep the pulp of the tooth without growing cells from it," she said. "I opted for both." From there, she said, the dentist shipped the extracted teeth overnight in a special package.

Bassetto said she paid less than $2,000 upfront, and now $10 a month for continued storage.

So is banking teeth something parents should be doing?

In a policy statement, the American Academy of Pediatric Dentistry "encourages dentists to follow future evidence-based literature in order to educate parents about the collection, storage, viability, and use of dental stem cells with respect to autologous regenerative therapies."

"Right now, I don't think it is a logical thing to do. That's my personal opinion," said Robey of the National Institute of Dental and Craniofacial Research. As of today, "we don't have methods for creating a viable tooth. I think they're coming down the pike, but it's not around the corner."

Science also does not yet support using dental pulp stem cells for other purposes.

"That's not to say that in the future, somebody could come up with a method that would make them very beneficial," Robey said.

Still, she observed, if science made it possible to grow natural teeth from stem cells and you were in a car accident, for example, and lost your two front teeth, you'd probably be "very happy to give up a third molar to use the cells in the molar to create new teeth." Third molars are fairly expendable, she said.

Plus, Robey explained, it may not be necessary to bank teeth: Another type of stem cell, known as induced pluripotent stem cells, can be programmed into almost any cell type.

"It's quite a different story than banking umbilical cord blood, which we do know contains stem cells that re-create blood," Robey said.

"So cord blood banking -- and now we have a national cord blood bank as opposed to private clinics -- so there's a real rationale for banking cord blood, whereas the rationale for banking baby teeth is far less clear," Robey said.

And there's no guarantee that your long-cryopreserved teeth or cells will be viable in the future. Banking teeth requires proper care and oversight on the part of cryopreservation companies, she said. "I think that that's a big question mark. If you wanted to get your baby teeth back, how would they handle that? How would they take the tooth out of storage and isolate viable cells?"

Provia's Laning, who has "successfully thawed cells that have been frozen for more than 30 years," dismissed such ideas.

"Cryopreservation technology is not the problem here," he said. "Stem cells from bone marrow and other sources have been frozen for future clinical use in transplants for more than 50 years. Similarly, cord blood has a track record of almost 40 years." The technology for long-term cryopreservation has been refined over the years without any substantial changes, he said.

Despite issues and doubts, Miller, of the pediatric dentistry academy, said parents still need to consider banking baby teeth.

A grandparent, he is making the decision for his own family.

"It's really at its infancy, much of this research," he said. "There's a very strong chance there's going to be utilization for these stem cells, and they could be life-saving."

He believes that saving baby teeth could benefit not only his grandchildren but also their older siblings and various other family members if their health goes awry and a stem cell treatment is needed.

"The science is strong enough to show it's not science fiction," Miller said. "There's going to be a significant application, and I want to give my grandkids the opportunity to have those options."

Aside from cost, Miller said there are other considerations: "Is this company going to be around in 30, 40 years?" he asked. "That's not an easy thing to figure out."

Having taken the leap, Bassetto doesn't worry.

"In terms of viability, you know, if something were to happen with the company, you could always get what's stored and move it elsewhere, so I felt I was protected that way," she said. She feels "pretty confident" with her decision and plans to store her grandchildren's baby teeth.

Still, she concedes that her circumstances may be rare.

"Not everybody's going to be touched by some kind of disease where it just hits home," Bassetto said. "For me, that made it a no-brainer."
