Stem Cell Therapy – State of the art treatment for pain

In most cases, 2 oz. (60 cc) of bone marrow aspirate is required. The aspirate includes platelets, mesenchymal stem cells, and other kinds of stem cells used in adult stem cell therapy. After aspiration, the stem cell tissue is separated from non-useful substances and cells via multiple filtration techniques. The bone marrow is placed inside a special container, which in turn is placed into a machine known as a centrifuge. The centrifuge spins the material at a high rate of speed, and this process separates the platelets and stem cells from the remainder of the blood products. It is this concentration of bone marrowcalled BMAC, or bone marrow aspiration concentrate that is injected to the site of tissue damage or injury. We use ultrasound and nerve stimulator guidance to increase the accuracy of administration

Once introduced, the platelets then release signal proteins and growth factors which activate the stem cells to divide rapidly. Stem cells by themselves are unable to repair the injured area. These cells have to be properly directed, and platelets perform this function. In effect, stem cells are construction workers and the platelets are their supervisors. Once they are activated, these stem cells perform a variety of valuable functions. Apart from repairing damage to the injured areas, they help damaged cells repair themselves and participate in the repairing process.

Cold virus, stem cells tested to destroy deadly brain cancer – Medical Xpress

A first-of-a-kind neural stem cell therapy that works with a common cold virus to seek out and attack a lethal and aggressive brain cancer is being tested at Northwestern Medicine in a Phase I clinical trial for patients newly diagnosed with malignant glioma.

The novel drug to treat malignant glioma, notorious for recurring after typical bouts of standard cancer treatment, was developed by a Northwestern scientist and has been approved as an investigational drug by the U.S. Food and Drug Administration. This is only the second time the University has supported and filed an investigational new drug as a sponsor.

"We have discovered that combining stem cells with a virus causes the new drug to react like a cancer-seeking missile targeting cancerous cells in the brain" said principal investigator, Dr. Maciej Lesniak, the Michael J. Marchese Professor and chair of neurological surgery at Northwestern University Feinberg School of Medicine and a neuro-oncologist at Northwestern Medicine. "If it works in humans, it could be a powerful weapon against brain cancer and an option that our patients are desperate for."

One reason malignant glioma recurs so often is because a small subpopulation of cancer cells, often deep in the brain tissue, is highly resistant to chemotherapy and radiation.

The pre-clinical work done by Lesniak and his team has shown that the approach being tested at Northwestern Medicine can target this population of therapy resistant cells, further delaying and sometimes even preventing tumor recurrence.

The stem cells used in the research came from a collaboration of researchers from City of Hope.

"We haven't seen significant progress in the last decade for patients with a brain tumor, and that is why it's crucial to do everything we can to find a better treatment for brain tumors," said Dr. Roger Stupp, a co-investigator who is working alongside Lesniak on this clinical trial. "Combining novel therapy with medical expertise, we are able to get one step closer to eradicating this lethal disease."

Stupp, a world-renowned neuro-oncologist, recently joined Northwestern Medicine as director of neuro-oncology and associate director for strategic initiatives at the Robert H. Lurie Comprehensive Cancer Center of Northwestern University. He is best known for developing temozolomide in combination with radiation as the standard-of-care chemotherapy for patients with glioblastoma.

Lesniak and his team of scientists are starting to test the safety and dosage of the treatment in patients at Northwestern Memorial Hospital. Lesniak began the research more than a decade ago while at the University of Chicago and completed it when he moved to Northwestern in 2015.

This investigational new drug contains neural stem cells to deliver a potent virus responsible for the common cold, oncolyotic adenovirus, which is engineered to kill brain cancer cells. The novel treatment works synergistically with chemotherapy and radiation to enhance the standard cancer treatments effectiveness.

Malignant gliomas are the most aggressive forms of cancer and are predicted to affect nearly 20,000 new patients this year, according to the American Brain Tumor Association. Sometimes called the "grow-and-go" tumors, gliomas can make their own blood supply, which fuels the tumors' rapid growth and helps them hatch satellite tumors. Each tumor sends out tentacles that infiltrate and dig deep into normal brain tissue, making complete removal of cancerous cells impossible. Any cancerous cells in the brain left over from standard of care can cause the tumor to recur.

Lesniak plans to enroll up to 36 newly diagnosed patients with glioma. These patients will be divided into two groups: those with tumors that can be removed and those where the tumors are not removable by surgery.

Next step, Northwestern Memorial will extend this research to the collaborating partners at City of Hope Comprehensive Cancer Center in Duarte, California.

How a revolutionary stem cell treatment could save your heart – Express.co.uk

NC

Yet today the 59-year-old father of two is planning a dream family trip to South Africa, something that would have been unthinkable a mere nine months ago.

The reason for this remarkable transformation is that last September Gordon, who suffered from severe heart failure after a series of heart attacks, underwent revolutionary stem cell therapy to repair the diseased muscle tissue in his heart.

I couldnt walk up the stairs without having stabbing pains in my heart and burning in my lungs. Sometimes I had to crawl for the last few steps.

I felt so low and helpless, says Gordon, who is married to Joanne, 50, and lives in Thorneholme, East Yorkshire.

Within a week of the operation I could climb the stairs again. Small things like that have made a huge difference to my life.

More than a million people in the UK suffer from heart disease. The general term for heart disease is cardiomyopathy, a condition in which the walls of the heart chambers have become stretched, thickened or stiff.

GETTY-STOCK

This affects the hearts ability to pump blood around the body. Some types of cardiomyopathy are inherited and it can affect children and younger people.

Gordon Foster

In others, lifestyle factors such as smoking, an unhealthy diet or a sedentary lifestyle can be to blame. There is no cure and although it can be treated with drugs such as ACE inhibitors, they often have side effects and arent a permanent solution.

In Gordons case his condition was the result of a series of heart attacks, the first of which struck when he was 30.

I woke up one morning feeling horribly sick so I ran to the bathroom. I was banging my head on the floor to try to get rid of the pain in my chest, he recalls. Everybody thought I was a goner because it was such a massive heart attack.

10 Step plan to eliminate your risk of heart disease

Joanne and I got married two months later because she was worried I might not live until our wedding date.

However he did survive and he and Joanne went on to have two children, James, now 26, and Rebekah, 24. Then when James was just a year old Gordon had another heart attack and three years later, aged 37, he suffered a third.

He was diagnosed as suffering from heart failure which most commonly occurs following a heart attack when the heart muscle suffers irreparable damage.

Symptoms can include fatigue, shortness of breath and swelling. In severe cases people with heart failure are left unable to perform ordinary, day-to-day activities such as walking upstairs or are left breathless even when resting.

GETTY

By 2012 Gordons heart was functioning at just 17 per cent and he had been forced to retire on heart attack and three years later, aged 37, he suffered a third. from heart failure which most commonly occurs following a heart attack when the heart muscle suffers irreparable damage.

Symptoms can include fatigue, shortness of breath and swelling. failure are left unable to perform ordinary, day-to-day activities such as walking upstairs or are left breathless even when resting.

Functioning at just 17 per cent and he had been forced to retire on medical grounds from his job overseeing welding and fabricating sites.

For severely affected patients a heart transplant can be the only option but the chances of failure are high. Around 10 per cent of transplant patients die within a year of the operation and 25 per cent die within five years.

The need for treatment in this field has never been greater, says Professor Anthony Mathur, consultant cardiologist at St Bartholomews Hospital, London.

Now stem cell therapy is offering new hope to desperate patients and their families. The procedure involves extracting stem cells from bone marrow in the spine and injecting them into the heart.

Researchers hope that the stem cells, which are unique because they can grow into any type of body tissue, will grow into healthy heart cells and take over the work of the diseased or damaged ones.

GETTY-STOCK

The procedure takes about 20 minutes and patients can usually go home the following day. Gordon became the first man in the UK to be offered the operation under the Compassionate Treatment Programme funded by the Heart Cells Foundation charity at St Bartholomews Hospital after his doctor put him forward to take part in a trial.

The charity has so far raised more than 6.5million to fund the Stem Cell Research Programme and is campaigning to raise further cash to treat thousands more patients.

Stem cell therapy is still in the development and research stage and the Compassionate Treatment Programme is funded purely by the Heart Cells Foundation charity, says its chairman Jenifer Rosenberg.

To treat one person costs 10,000 so we need the continued support of our donors to save lives.

The treatment is currently in the second phase of clinical trials and phase three will start once funding is secured. If this is successful it is hoped that the treatment could eventually be offered on the NHS.

Gordon says he and his family will be forever thankful to the Heart Cells Foundation and his medical team at St Bartholemews for saving his life.

Without them, I believe I wouldnt be here today, he says. Im now able to lead a near-normal life and Im enjoying every moment I spend with my wife and children. I now live every day with hope.

‘Sneakers,’ stem cells help heal Cheyenne Mountain Zoo’s giraffes – Colorado Springs Gazette

Two medical breakthroughs have helped heal two giraffes at Cheyenne Mountain Zoo in recent weeks, the zoo announced Wednesday.

Mahali, a 14-year-old male giraffe who suffered from chronic lameness and had not been moving well, is believed to be the first in the world to be injected with stem cells grown from giraffe blood, according to a news release from the zoo.

Stem cell therapy was chosen in the efforts led by Dr. Liza Dadone, the zoo's head veterinarian, because it has proven to repair damaged tissue. Staff at Colorado State University's James L. Voss Veterinary Teaching Hospital in Fort Collins helped with the treatment.

Nearly a month after the procedure, when Mahali was injected with about 100 million stem cells, thermographic images of the giraffe's front legs show "a considerable decline" in inflammation in his front left leg, the leg that had been giving him trouble, the zoo said.

"This is meaningful to us not only because it is the first time a giraffe has been treated with stem cells, but especially because it is bringing Mahali some arthritis relief and could help other giraffes in the near future," Dadone said in a written statement.

Dadone said it's not clear whether the successful results are due only to the stem cell treatment or a combination of treatments.

"Prior to the procedure, he was favoring his left front leg and would lift that foot off the ground almost once per minute," she said in the statement. "During the immobilization, we did multiple treatments that included hoof trims, stem cell therapy and other medications. Since then, Mahali is no longer constantly lifting his left front leg off the ground and has resumed cooperating for hoof care. A few weeks ago, he returned to life with his herd, including yard access. On the thermogram, the marked inflammation up the leg has mostly resolved."

Twiga, a 14-year-old female giraffe with advanced arthritis and osteoporosis in her feet, was fitted with custom shoes with the help of farriers Steve Foxworth and Chris Niclas of the Equine Lameness Prevention Organization.

"We've had Twiga on medicine to help reverse her osteoporosis, but we wanted to do more to protect her feet. So with the help of the farriers, we gave her 'giraffe sneakers' to help give her some extra cushion," Dadone said in a written statement.

The giraffe's behavior was immediately changed - "Twiga instantly shifted her weight off of her right foot, indicating she was comfortable and her pain had considerably lessened" - but she will likely wear the shoes for about six more weeks, the zoo said.

Giraffes' size can make them more susceptible to issues like arthritis and osteoporosis. "Like all animals, these issues are exacerbated as they age," according to the zoo news release.

The zoo has a herd of 17 giraffes, including a newborn in April. The calf, a girl, was the 199th to be born in the 63-year history of the zoo's breeding program.

Giraffes' status was recently changed from "least concern" to "vulnerable" by the International Union for Conservation of Nature because the population in the wild has decreased by 40 percent in the last 30 years, the zoo said.

California’s stem cell agency confronts uncertain future – Capitol Weekly

News

by DAVID JENSEN posted 05.23.2017

C. Randal Mills, the 45-year-old CEO of Californias $3 billion stem cell research program, is a man who loves his milestones.

A private pilot, he charts his course in the air from one specific point to the next. Three years ago, Mills brought that same sort of navigation to the state stem cell agency. Miss one of the agencys milestones, and if youre a stem cell scientist you may not crash and burn, but you could lose millions of dollars in research funding from the state.

Since the agencys inception, it has spent money at the rate of $22,000 an hour. But it has yet to finance a stem cell therapy that is available to the general public.

Mills has left an indelible stamp on the agency with his emphasis on concrete, measurable results. But he is resigning from the research program at the end of June in the midst of what some say is its last stage. His surprise departure to head the worlds largest bone marrow donor organization shocked many in Californias stem cell community. And it added to the unease about its future along with the future of possible stem cell therapies.

The California Institute for Regenerative Medicine (CIRM), as the agency is formally known, expects to run out of cash for new awards in just three years, which is a blink of an eye in biotech research. Since the agencys inception, it has spent money at the rate of $22,000 an hour. But it has yet to finance a stem cell therapy that is available to the general public. Nonetheless, there is talk of a new, $5 billion stem cell bond measure on the November 2018 ballot.

CIRM was created by California voters in 2004 when they approved a 10,000-word ballot initiative, Proposition 71. Voters also provided the agency with $3 billion in borrowed money (state bonds) that flows directly to the agency, untouched by the governor or the Legislature. The bond financing roughly doubles the cost of the research because of the interest expense.

Passage of the California initiative triggered a fresh wave of optimism and headlines that spoke of a new California gold rush this time in biotech.

The $34 million ballot campaign 13 years ago generated expectations that miraculous stem cell therapies were right around the corner. More than 40 Nobel Prize-winning scientists and actors such as Michael J. Fox campaigned for it. Christopher Reeve, who portrayed Superman but was later paralyzed in an accident, was featured in a TV ad that appeared after his death.

Stand up for those who cant, said Reeve from his wheelchair, calling on voters to support Proposition 71.

The agency came into being at a low point for the field of stem cell research. President George W. Bush had restricted federal funding for research using human embryonic stem cells. Researchers were disheartened. Younger scientists shied away from the field because of the funding uncertainties.

Passage of the California initiative triggered a fresh wave of optimism and headlines that spoke of a new California gold rush this time in biotech. While the gold rush is yet to be seen, the agency can point to a number of markers that it says show the program was worth the effort.

What particularly excites Mills and patient advocates are the dramatic and emotional stories of the handful of patients who have benefited from CIRM-connected clinical trials.

Independent, authoritative voices assessing the performance of the agency are almost non-existent. The Legislature has no oversight of the enterprise nor does the governor

Evangelina Padilla Vaccaro is one. Evangelina is alive today as the result of work at UCLA that has saved the lives of more than 30 persons afflicted with a fatal, rare immune disorder. She is perhaps the only four-year-old ever to address the governing board of the stem cell agency.

Thank you, she whispered to the board at a meeting last December. Evangelinas mother said more, her voice cracking, Thank you for keeping my family complete.

CIRM has pumped $52 million into the immune disorder research, which had been already underway for decades. However, only a handful of people can participate in the CIRM-connected clinical trials, such as Evangelinas, because of their experimental nature. Both the federal Food and Drug Administration, which ultimately controls the trials, and researchers move slowly to bring risky therapies to the general public.

The December meeting highlighted the personal success stories that can be found in the work financed by the agency. But four months later the prestigious scientific journal Nature carried a gloomier take. It published a piece on CIRM with a headline that described the agency as being in its last stage and facing its final test.

CIRM has made California a world leader in stem cell research, attracting some of the most talented scientists to the state to develop new treatments and funding world-class research facilities CIRM

The agency, however, is not yet ready for hospice care. Recently asked to cite the five most important things that Californians should know about the agency and its future, Kevin McCormack, senior director for communications, responded with much more. (The complete text of his statement can be found here.) His short list:

1) Research we have supported has cured more than 30 children of a fatal rare immune disorder. That same approach has also cured a young man of another rare immune disorder and is now being used to help find a cure for sickle cell anemia a condition that affects more than 100,000 people in the US, most of them African Americans.

2) We have funded 29 projects in clinical trials for a variety of diseases including heart disease, cancer, diabetes, HIV/AIDS, spinal cord injuries and the leading cause of vision loss and blindness in the US.

3) We are focused on adding another 40 new clinical trials by 2020, including rare diseases and those affecting children.

4) We place patients at the heart of everything we do and every decision we make. Nothing gets done at CIRM, including what we fund and how clinical trials are designed, without the input of patients and patient advocates. They know best what needs to be done and their voices are essential in making decisions about treatments that could change their lives, even save their lives.

5) CIRM has made California a world leader in stem cell research, attracting some of the most talented scientists to the state to develop new treatments and funding world-class research facilities in which the research is conducted free from federal restrictions.

Independent, authoritative voices assessing the performance of the agency are almost non-existent. The legislature has no oversight of the enterprise nor does the governor, a condition permitted legally by the ballot initiative. The initiative did create a body called the Citizens Financial Accountability and Oversight Committee, which meets once a year to consider the agencys finances. In recent years, it has been less than aggressive.

Jim Lott is a member of that group, which is chaired by the state controller. Over the years, however, Lott has expressed dissatisfaction with some aspects of the agency. Lott, who was executive vice president for decades of the Hospital Association of Southern California, said in an interview that the agency has done a really good job in seeding programs.

But he also described the ballot initiative as a very expensive tease. Lott said, They teased the public. They teased us with with Proposition 71. And they did not deliver on the tease, and I dont want them to be able to get away with that again.

According to calculations by theCalifornia Stem Cell Report, about 90 percent of the agencysawards have gone to institutionsthat are or have been represented onthe governing board.

If CIRM is to continue, he said it should be wrapped into the regular structure of state government and funded on a normal, annual budget basis. He also said the governing board should become advisory instead of currently making decisions on each application for state money.

We need to do this in a more responsible and accountable way, Lott said.

The most comprehensive review of the agency came in 2012 when the Institute of Medicine (IOM) reported the findings of its 17-month study of the agency. The IOM is a highly regarded national organization that provides studies on science, health and medical issues. The stem cell agency governing board commissioned the study at a cost of $700,000.

(The IOM has been renamed the Health and Medicine Division of the National Academies of Sciences, Engineering, and Medicine.)

Harold Shapiro, former president of Princeton University and chairman of the IOM study, said in 2012 that the agency has done a remarkably good job overall in giving the state a prominent position in regenerative medicine. But he said the stem field has changed and the agency needed to change with it.

Currently, the top 10 recipients of CIRM largesse all have ties to its governing board.

When Shapiro appeared before the board to present the findings, some CIRM directors bridled at the studys far-reaching recommendations, many of which dealt with the built-in conflicts of interest on the board. The IOM proposals would have removed all board members from the grant review process and limited them to voting on a slate of applications rather than individual applications. More disclosure of personal conflicts of interest, including health matters, was also recommended.

Far too many board members represent organizations that receive CIRM funding or benefit from that funding. These competing personal and professional interests compromise the perceived independence of the ICOC (the CIRM governing board), introduce potential bias into the boards decision making and threaten to undermine confidence in the board, the IOM report said.

According to calculations by the California Stem Cell Report, about 90 percent of the agencys awards have gone to institutions that are or have been represented on the governing board.

Currently, the top 10 recipients of CIRM largesse all have ties to its governing board. The institutions are Stanford University, $320 million; UCLA, $275 million; UC San Diego, $177 million; UC San Francisco, $143 million; UC Davis, $129 million; USC, $110 million; UC Irvine, $106 million; City of Hope, $72 million; Cedars-Sinai Medical Center, $62 million, and Gladstone Institutes, $61 million.

We changed the way our board votes to ensure there would be no more concerns about the perception of conflict of interest. CIRM

The ballot initiative gave virtually all the institutions that were significant players in stem cell research a seat at the board table. The 29 board members cannot vote on applications from institutions that they are tied to. But they do set the rules, standards and scope of the grant programs.

In response to the IOM, the board approved what were termed dramatic changes in voting and other procedures to ease the perception of conflicts of interest. Shapiro called the changes significant.

The agency said last week,We changed the way our board votes to ensure there would be no more concerns about the perception of conflict of interest. By preventing heads of institutions who could receive stem cell funds from voting on any funding issue, we took that off the table so that we can focus on our main goal, helping patients.

The conflict case that has attracted the most public attention, however, did not involve directors, but Alan Trounson, Mills predecessor as president of agency. Seven days after Trounson left his CIRM post in 2014, he was appointed to the board of StemCells, Inc., a Newark, Calif. firm that was awarded more than $40 million in funding while Trounson was president of the agency. Trounson ultimately received $435,000 in total compensation for his duties on the StemCells, Inc., board. Trounson has denied any wrongdoing.

The Fair Political Practices Commission initiated an investigation and said in a 2015 letter to Trounson there was insufficient evidence to demonstrate a legal violation.

The loss of Mills has triggered concerns among some scientists that more CIRM employees will begin to look for work elsewhere. Mills has identified the risk of losing employees in his strategic plan. He has talked about finding ways to keep people on board, but nothing has been publicly disclosed.

On May 2, when Mills announced his coming departure to lead the National Marrow Donor Program in Minneapolis, the agency coupled the news with designation of an interim president, Maria Millan. She is currently the CIRM vice president for therapeutics. The agencys directors will discuss finding a permanent replacement at a closed-door meeting in July.

Mills said in an interview that Millan, a physician who has been with the agency since 2012, is the obvious choice to succeed him. Prior to joining CIRM, she served as a vice president and acting chief medical officer of StemCells, Inc., and was director of the pediatric organ transplant program at Stanford.

CIRMs general counsel, James Harrison is also leaving at the end of June. His announcement came in March, prior to Mills resignation. Harrison is a partner in the Oakland law firm of Remcho, Johansen & Purcell and wrote part of the stem cell initiative. Harrison worked under a contract between his firm and CIRM. He has been associated with the agency since its inception and has been a key leader with influence well beyond narrow legal issues.

Today CIRM is downto its last $650 million, having committed $2.2 billion for awards with the remainder going for operational expenses. The $650 million sounds ample, but when clinical trials are receiving $20 million in a single award, the money can go fast.

Coming to the financial rescue of CIRM may be Robert Klein, the Palo Alto multimillionaire real estate investment banker who led the 2004 campaign and became the agencys first chairman. He says he is ready to back a $5 billion bond issue for California voter approval in November of 2018. Americans for Cures, his nonprofit group, which shares space in Kleins Palo Alto headquarters, plans to poll California voters this fall, with the expectation that 70 percent of them will back the agency.

Klein did not respond to emailed questions for this article. But he made an appearance earlier this year at a CIRM-related event at the City of Hope in Duarte, Ca. Klein declared that a medical revolution is underway. And he said that the state of California now has the opportunity and privilege to lift the human condition if it will continue support of its 12-year-old stem cell research effort.

California's stem cell agency confronts uncertain future - Capitol Weekly

Study identifies RNA molecule that shields breast cancer stem cells … – Princeton University

Researchers from Princeton Universitys Department of Molecular Biology have identified a small RNA molecule that helps maintain the activity of stem cells in both healthy and cancerous breast tissue. The study, which will be published in the June issue of Nature Cell Biology, suggests that this "microRNA" promotes particularly deadly forms of breast cancer and that inhibiting the effects of this molecule could improve the efficacy of existing breast cancer therapies.

Stem cells give rise to the different cell types in adult tissues but, in order to maintain these tissues throughout adulthood, stem cells must retain their activity for decades. They do this by "self-renewing" dividing to form additional stem cells and resisting the effects of environmental signals that would otherwise cause them to prematurely differentiate into other cell types.

Many tumors also contain so-called "cancer stem cells" that can drive tumor formation. Some tumors, such as triple-negative breast cancers, are particularly deadly because they contain large numbers of cancer stem cells that self-renew and resist differentiation.

To identify factors that help non-cancerous mammary gland stem cells (MaSCs) resist differentiation and retain their capacity to self-renew, Yibin Kang, the Warner-Lambert/Parke-Davis Professor of Molecular Biology, and colleagues searched for short RNA molecules called microRNAs that can bind and inhibit protein-coding messenger RNAs to reduce the levels of specific proteins. The researchers identified one microRNA, called miR-199a, that helps MaSCs retain their stem-cell activity by suppressing the production of a protein called LCOR, which binds DNA to regulate gene expression. The team showed that when they boosted miR-199a levels in mouse MaSCs, they suppressed LCOR and increased normal stem cell function. Conversely, when they increased LCOR levels, they could curtail mammary gland stem cell activity.

Kang and colleagues found that miR-199a was also expressed in human and mouse breast cancer stem cells. Just as boosting miR-199a levels helped normal mammary gland stem cells retain their activity, the researchers showed that miR-199a enhanced the ability of cancer stem cells to form tumors. By increasing LCOR levels, in contrast, they could reduce the tumor-forming capacity of the cancer stem cells. In collaboration with researchers led by Zhi-Ming Shao, a professor at Fudan University Shanghai Cancer Center in China, Kang's team found that breast cancer patients whose tumors expressed large amounts of miR-199a showed poor survival rates, whereas tumors with high levels of LCOR had a better prognosis.

Kang and colleagues found that LCOR sensitizes cells to the effects of interferon-signaling molecules released from epithelial and immune cells, particularly macrophages, in the mammary gland. During normal mammary gland development, these cells secrete interferon-alpha to promote cell differentiation and inhibit cell division, the researchers discovered. By suppressing LCOR, miR-199a protects MaSCs from interferon signaling, allowing MaSCs to remain undifferentiated and capable of self-renewal.

The microRNA plays a similar role during tumorigenesis, protecting breast cancer stem cells from the effects of interferons secreted by immune cells present in the tumor. "This is a very nice study linking a normal and malignant mammary gland stem cell program to protection from immune modulators," said Michael Clarke, the Karel H. and Avice N. Beekhuis Professor in Cancer Biology at Stanford School of Medicine, Institute of Stem Cell Biology and Regenerative Medicine, who first discovered breast cancer stem cells but was not involved in this study. "It clearly has therapeutic implications for designing strategies to rationally target the breast cancer stem cells with immune modulators."

Toni Celi-Terrassa, an associate research scholar in the Kang lab and the first author of the study, said, "This study unveils a new property of breast cancer stem cells that give them advantages in their interactions with the immune system, and therefore it represents an excellent opportunity to exploit for improving immunotherapy of cancer."

"Interferons have been widely used for the treatment of multiple cancer types, Kang said. "These treatments might become more effective if the interferon-resistant cancer stem cells can be rendered sensitive by targeting the miR-199a-LCOR pathway."

Stem cell agency’s response to questions about its performance … – Capitol Weekly

by DAVID JENSEN posted 05.23.2017

Eds Note: Here is the full text of the response from the California stem cell agency to a query about the five most important things that it thinks Californians should know about the $3 billion effort. The information was provided by Kevin McCormack, senior director for communications at the agency.

Its hard to limit it to 5 because we have done so many different things that, in their own way, are pioneering and ground-breaking. Its like asking someone to choose their favorite child. We love them all equally.

1) Research we have supported has cured more than 30 children of a fatal rare immune disorder. That same approach has also cured a young man of another rare immune disorder and is now being used to help find a cure for sickle cell anemia a condition that affects more than 100,000 people in the US, most of them African Americans

2) We have funded 29 projects in clinical trials for a variety of diseases including heart disease, cancer, diabetes, HIV/AIDS, spinal cord injuries and the leading cause of vision loss and blindness in the US

3) We are focused on adding another 40 new clinical trials by 2020, including rare diseases and those affecting children

4) We place patients at the heart of everything we do and every decision we make. Nothing gets done at CIRM, including what we fund and how clinical trials are designed, without the input of patients and patient advocates. They know best what needs to be done and their voices are essential in making decisions about treatments that could change their lives, even save their lives

5) CIRM has made California a world leaders in stem cell research, attracting some of the most talented scientists to the state to develop new treatments and funding world-class research facilities in which the research is conducted free from federal restrictions

6) We have created the CIRM Alpha Stem Cell Clinic Network and the Stem Cell Center, two unique institutions that combined can improve the ability of researchers to get their products approved for clinical trials, and to increase the chances those clinical trials will be successful. These are already attracting both CIRM and non-CIRM funded projects to California, and will be an enduring contribution to the development of stem cell projects of all kinds.

In addition we created the iPSC Bank which is developing a repository of more than 3,000 different cell types for research into the causes, and potential treatments for diseases as varied as Alzheimers and autism, heart disease and vision loss.

We are helping create new jobs and generate new taxes. A 2014 economic impact report showed that by that year alone we had generated $284 million in new taxes for the state and helped create 38,000 new job years (thats economist speak for 38,000 jobs that last one year, 19,000 that last two, etc.)

We changed the way our Board votes to ensure there would be no more concerns about the perception of conflict of interest. By preventing heads of institutions who could receive stem cell funds from voting on any funding issue, we took that off the table so that we can focus on our main goal, helping patients.

We have created leadership and trainee programs such as our Bridges program that are helping train the next generation of stem cell scientists.

We played a key role in advancing the 21st Century Cures Act and that two of the first projects approved for accelerated review and approval are CIRM-funded clinical trials. Humacyte was the very first project granted Regenerative Medicine Advanced Therapy and last week jCyte was granted RMAT designation for its work in treating retinitis pigmentosa (heres a fabulous blog about that).

Dont forget, we have around $650 million left to spend, thats far more than any other state has available (New York, for example has $50m a year, Connecticut just $10m ) and more than many countries, and we intend to use that money to continue to accelerate the research that will provide new treatments and cures.

Momentum is a general term used to describe the speed at which prices move over a given time period. Generally, changes in momentum tend to lead to changes in prices. This expert shows the current values of four popular momentum indicators.

Stochastic Oscillator

One method of interpreting the Stochastic Oscillator is looking for overbought areas (above 80) and oversold areas (below 20). The Stochastic Oscillator is 56.7031. This is not an overbought or oversold reading. The last signal was a buy 26 period(s) ago.

Relative Strength Index (RSI)

The RSI shows overbought (above 70) and oversold (below 30) areas. The current value of the RSI is 64.84. This is not a topping or bottoming area. A buy or sell signal is generated when the RSI moves out of an overbought/oversold area. The last signal was a sell 36 period(s) ago.

Commodity Channel Index (CCI)

The CCI shows overbought (above 100) and oversold (below -100) areas. The current value of the CCI is 269.This is an overbought reading. However, a signal isnt generated until the indicator crosses below 100. The last signal was a sell 2 period(s) ago.

MACD

The Moving Average Convergence/Divergence indicator (MACD) gives signals when it crosses its 9 period signal line. The last signal was a buy 13 period(s) ago.

Scientists just created the world’s first lab-grown human blood stem cells – Yahoo News

In a breakthrough of potentially enormous importance, researchers have grown the stem cells that produce blood inside a lab for the first time. The advance could help pave the way for both the creation of blood for transfusions, as well as for treating patients with blood disorders using their own cells, instead of having to rely on donor marrow transplants.

Bone marrow transplants offer a cure to leukemia, sickle cell disease, and a variety of other blood disorders, Dr. Raphael Lis, from Weill Cornell Medical College in New York, told Digital Trends. The problem is that many patients dont have a well-matched donor to provide the marrow needed to reconstitute their blood with healthy cells. To address this challenge, we and others have been trying to develop reliable, lab-based methods to generate the essential blood-producing component of bone marrow: Hematopoietic stem cells.

To make their blood stem cells, the Weill Cornell researchers took cells from the walls of animal lungs, and then used aset of four proteins they had identified that encouraged them to form blood stem cells. In an experiment, the reprogrammed blood stem cells were shown to regenerate the entire blood system of mice for the duration of their lifespan, as well as providing a boost to theirimmune systems.

The results demonstrate a proof-of-concept for efficiently converting the cells that line blood vessels into fully-functioning stem cells, which can be transplanted to provide a lifetime supply of new and healthy blood cells.

We are now testing our method in large animals, Lis continued. We devised a new nonintegrative approach we are currently testing in monkeys in collaboration with the Fred Hutchinson Institute.Providing that these monkeys show positive results and no sign of hematologic malignancies, Lis said that this would allow us to push this method one step close to translation to clinic.

Lis team isnt the only one to experience a breakthrough in this area. Another newly published study coming out of Harvard Medical School started withhuman pluripotent stem cells, referring to stem cells capable of turning into any other type of cell in the human body. They then applied proteins which they discovered triggered the pluripotent cells to transform into blood stem cells. In tests also involving mice, these produced new red and white blood cells, in addition to platelets.

Taken together, the two projects represent a significant advance. You can read more about the Weill Cornell Medical College study here, and the Harvard Medical School study here.
