Fourteenth Patient Dosed in Neuralstem ALS Stem Cell Trial

By JoanneRUSSELL25

ROCKVILLE, Md., March 7, 2012 /PRNewswire/ -- Neuralstem, Inc. (NYSE Amex: CUR) announced that the second patient to receive stem cells in the cervical (upper back) region of the spine was dosed on February 29th in the ongoing Phase I trial of its spinal cord neural stem cells in amyotrophic lateral sclerosis (ALS or Lou Gehrig's disease). Patient 14 is also the first woman to be treated in the trial. Stem cell transplantation into the cervical region of the spinal cord couldsupport breathing, a key function that is lost as ALS progresses. The first twelve patients in the trial received stem cell transplants in the lumbar (lower back) region of the spinal cord only.

"This cohort of patients represents another first for our trial, as we transplant cells directly into the gray matter of the spinal cord in the cervical region," said Karl Johe, PhD, Neuralstem's Chairman and Chief Scientific Officer. "We are delighted that the surgeries are progressing in a region that could have a significant impact on the quality of life for ALS patients. With the safe transplantation of our 14th patient, we are well are on our way to demonstrating the safety of our novel procedure."

About the Trial The Phase I trial to assess the safety of Neuralstem's spinal cord neural stem cells and intraspinal transplantation method in ALS patients has been underway since January 2010. The trial is designed to enroll up to 18 patients. The first 12 patients were each transplanted in the lumbar (lower back) region of the spine, beginning with non-ambulatory and advancing to ambulatory cohorts. The trial has now progressed to the final six patients. Each is in the cervical (upper back) region of the spine. The entire 18-patient trial concludes six months after the final surgery.

About Neuralstem Neuralstem's patented technology enables the ability to produce neural stem cells of the human brain and spinal cord in commercial quantities, and the ability to control the differentiation of these cells constitutively into mature, physiologically relevant human neurons and glia. Neuralstem is in an FDA-approved Phase I safety clinical trial for amyotrophic lateral sclerosis (ALS), often referred to as Lou Gehrig's disease, and has been awarded orphan status designation by the FDA.

In addition to ALS, the company is also targeting major central nervous system conditions with its cell therapy platform, including spinal cord injury, ischemic spastic paraplegia and chronic stroke. The company has submitted an IND (Investigational New Drug) application to the FDA for a Phase I safety trial in chronic spinal cord injury.

Stem Cell Pioneers Converge in Portland to Discuss and Celebrate a Revolutionary New Stem Cell Entering Human Clinical …

By JoanneRUSSELL25

SAN DIEGO, CA and PORTLAND, OR--(Marketwire -02/28/12)- Medistem Inc. (Pinksheets: MEDS.PK - News) announced today its Annual "Evening with Medistem" Event will take place in Portland, Oregon on March 7th, 2012. The event is being hosted by Vladimir Zaharchook, Vice Chairman at Medistem, Inc., and will feature stem cell luminaries and pioneers working with Medistem including Dr. Amit Patel, Director of Regenerative Medicine at University of Utah and the first person to administer stem cells into patients with heart failure, Dr. Michael Murphy, Vascular Surgeon at Indiana University and Principal Investigator for Medistem's FDA clinical trial in patients with risk of amputation, and Dr. Alan Lewis, former CEO of the Juvenile Diabetes Research Foundation, advisory board member of Medistem.

In 2007 Medistem discovered an entirely new type of stem cell, the Endometrial Regenerative Cell (ERC). This cell has proven it is a "universal donor" and can be used to treat many more conditions compared to other types of stem cells. The company received FDA clearance to begin clinical trials in September of 2011 for critical limb ischemia, a condition that is associated with amputation. Medistem is also running a Phase II clinical trial for heart failure using the new stem cell. The ERC stem cell does not involve the highly controversial use of fetal tissue, can be produced very economically and administered to the patient in a very simple manner. Medistem is exploring ways to expand clinical trials of its stem cell into other diseases.

"Stem cells and regenerative medicine offer hope in clinical conditions in which hope previously did not exist," said Dr. Stanley Cohan, Head of Neurology at the St Vincent's Hospital, the largest center for treatment of multiple sclerosis in the Pacific Northwest, who will be attending the event. "We are honored in the Portland community to have this distinguished team of accomplished researchers and medical doctors convene here and discuss with us possible collaborations."

"As a long-time member of the Portland academic community, it is exciting to have companies such as Medistem to visit us and share their experiences 'from the trenches' of what it takes to push a cellular drug through the FDA," said Dr. Shoukrat Milipotiv, Associate Scientist in the Division of Reproductive & Developmental Sciences of ONPRC, Oregon Stem Cell Center and Departments of Obstetrics & Gynecology and Molecular & Medical Genetics, and co-director of the ART/ESC core at the Center. He is an internationally recognized researcher in the area of stem cells.

"The Event is an annual celebration to honor our team and collaborators for the successes of the previous year, while at the same time educate the local business and medical community on the latest research on stem cells not just at Medistem but internationally," said Thomas Ichim, Ph.D Chief Executive Officer of Medistem Inc. "2012 is particularly exciting for us due to approvals for two clinical trials, and the initiation of patient treatments within this context."

About Medistem Inc.

Medistem Inc. is a biotechnology company developing technologies related to adult stem cell extraction, manipulation, and use for treating inflammatory and degenerative diseases. The company's lead product, the endometrial regenerative cell (ERC), is a "universal donor" stem cell being developed for critical limb ischemia and heart failure.

Rethinking Infertility: Study Shows Women Have Egg-Producing Stem Cells

By JoanneRUSSELL25

Are women born with all the eggs they'll ever have? Harvard scientists say possibly not. Their discovery of stem cells in human ovaries could someday help infertile women produce new eggs.

For 60 years, doctors have believed women were born with all the eggs they’ll ever have. Now Harvard scientists are challenging that dogma, saying they’ve discovered the ovaries of young women harbor very rare stem cells capable of producing new eggs.

If Sunday’s report is confirmed, harnessing those stem cells might one day lead to better treatments for women left infertile because of disease — or simply because they’re getting older.

“Our current views of ovarian aging are incomplete. There’s much more to the story than simply the trickling away of a fixed pool of eggs,” said lead researcher Jonathan Tilly of Harvard’s Massachusetts General Hospital, who has long hunted these cells in a series of controversial studies.

Tilly’s previous work drew fierce skepticism, and independent experts urged caution about the latest findings.

A key next step is to see whether other laboratories can verify the work. If so, then it would take years of additional research to learn how to use the cells, said Teresa Woodruff, fertility preservation chief at Northwestern University’s Feinberg School of Medicine.

Still, even a leading critic said such research may help dispel some of the enduring mystery surrounding how human eggs are born and mature.

“This is going to spark renewed interest, and more than anything else it’s giving us some new directions to work in,” said David Albertini, director of the University of Kansas’ Center for Reproductive Sciences. While he has plenty of questions about the latest work, “I’m less skeptical,” he said.

Scientists have long taught that all female mammals are born with a finite supply of egg cells, called ooctyes, that runs out in middle age. Tilly, Mass General’s reproductive biology director, first challenged that notion in 2004, reporting that the ovaries of adult mice harbor some egg-producing stem cells. Recently, Tilly noted, a lab in China and another in the U.S. also have reported finding those rare cells in mice.

But do they exist in women? Enter the new work, reported Sunday in the journal Nature Medicine.

First Tilly had to find healthy human ovaries to study. He collaborated with scientists at Japan’s Saitama Medical University, who were freezing ovaries donated for research by healthy 20-somethings who underwent a sex-change operation.

Tilly also had to address a criticism: How to tell if he was finding true stem cells or just very immature eggs. His team latched onto a protein believed to sit on the surface of only those purported stem cells and fished them out. To track what happened next, the researchers inserted a gene that makes some jellyfish glow green into those cells. If the cells made eggs, those would glow, too.

“Bang, it worked — cells popped right out” of the human tissue, Tilly said.

Researchers watched through a microscope as new eggs grew in a lab dish. Then came the pivotal experiment: They injected the stem cells into pieces of human ovary. They transplanted the human tissue under the skin of mice, to provide it a nourishing blood supply. Within two weeks, they reported telltale green-tinged egg cells forming.

That’s still a long way from showing they’ll mature into usable, quality eggs, Albertini said.

And more work is needed to tell exactly what these cells are, cautioned reproductive biologist Kyle Orwig of the University of Pittsburgh Medical Center, who has watched Tilly’s work with great interest.

But if they’re really competent stem cells, Orwig asked, then why would women undergo menopause? Indeed, something so rare wouldn’t contribute much to a woman’s natural reproductive capacity, added Northwestern’s Woodruff.

Tilly argues that using stem cells to grow eggs in lab dishes might one day help preserve cancer patients’ fertility. Today, Woodruff’s lab and others freeze pieces of girls’ ovaries before they undergo fertility-destroying chemotherapy or radiation. They’re studying how to coax the immature eggs inside to mature so they could be used for in vitro fertilization years later when the girls are grown. If that eventually works, Tilly says stem cells might offer a better egg supply.

Further down the road, he wonders if it also might be possible to recharge an aging woman’s ovaries.

The new research was funded largely by the National Institutes of Health. Tilly co-founded a company, OvaScience Inc., to try to develop the findings into fertility treatments.

Ovarian Stem Cells Produce Eggs in Method That May Aid Fertility

By JoanneRUSSELL25

February 27, 2012, 12:41 AM EST

By Ryan Flinn

Feb. 27 (Bloomberg) -- Stem cells taken from human ovaries were used to produce early-stage eggs by scientists in Boston who may have created a new method to help infertile women.

Females have a fixed number of eggs from birth that are depleted by the time of menopause. The finding, published today in the journal Nature Medicine, challenges the belief that their ovaries can’t make more. The research was led by Jonathan Tilly, the director of Massachusetts General Hospital’s Vincent Center for Reproductive Biology.

Tilly reported in 2004 that ovarian stem cells in mice create new eggs, or oocytes, in a way similar to how stem cells in male testes produce sperm throughout a man’s life. His latest work, if reproduced, would suggest the same is true for human ovaries, potentially pointing at new ways to aid fertility by delaying when the ovaries stop functioning.

“The 50-year-old belief in our field wasn’t actually based on data proving it was impossible, or not ongoing,” Tilly said in a telephone interview. “It was simply an assumption made because there was no evidence indicating otherwise. We have human cells that can produce new oocytes.”

In the study, healthy ovaries were obtained from consenting patients undergoing sex reassignment surgery. The researchers were able to identify ovarian stem cells because they express a rare protein that’s only seen in reproductive cells.

The stem cells from the ovaries were injected into human ovarian tissue that was then grafted under the skin of mice, which provided the blood supply that enabled growth. Within two weeks, early stage human follicles with oocytes had formed.

7-Million Eggs

A female is most endowed with oocytes, or eggs, as a fetus, when she has about 7 million. That number that drops to 1 million by birth, and around 300,000 by puberty. By menopause, the number is zero. Since the 1950’s, scientists thought that ovarian stem cells capable of producing new eggs are only active during fetal development.

“This paper essentially opens the door to the ability to control oocyte development in human ovaries,” Tilly said.

About 10 percent of women of child-bearing age in the U.S., or 6.1 million, have difficulty getting pregnant or staying pregnant, according to the Centers for Disease Control and Prevention. Most cases of female infertility are caused by problems with ovulation, hormone imbalance or age.

The study by Tilley and his colleagues offers “a new model system for understanding the human egg cell,” said David F. Albertini, director of the Center for Reproductive Services and professor in the department of molecular and integrative physiology at Kansas University, in a telephone interview.

‘Practical Applications”

Still, “there’s a long way to go before this has real practical applications. I’ve spent 35 years of my life studying egg cells and this is a cell that is at least as complicated as a neuron in the brain, if not more,” Albertini said.

The work needs to be reproduced and expanded by other scientists “to make it into something that will make us confident the cells are safe to use and we could actually use them to repopulate an egg-depleted ovary,” he said.

Tilly’s team is exploring the development of an ovarian stem-cell bank that can be cryogenically frozen and thawed without damage, unlike human eggs, he said. The researchers are also working to identify hormones and other growth factors for accelerating production of eggs from human ovarian stem cells and ways to improve in-vitro fertilization.

“The problem we face with IVF is we don’t have many eggs to work with,” he said. “These cells are renewable. If we are successful -- and it’s a big if -- in generating functioning eggs from these cells, we can generate as many eggs as we need to on a per patient basis.”

Tilly is also collaborating with researchers at the University of Edinburgh in the U.K. to determine whether the oocytes can be developed into fully mature human eggs for fertilizing. The U.S bans creating or fertilizing embryos for experimental purposes, he said.

A company Tilly co-founded, Boston-based OvaScience Inc., has licensed the technology for potential commercial applications.

Massachusetts General researchers discover stem cell that makes eggs

By JoanneRUSSELL25

Massachusetts General Hospital researchers reported today they have discovered a rare stem cell in women’s ovaries that they hope one day might be used to make eggs, a claim already generating vigorous debate among scientists familiar with the research.

For decades, it has been thought that women are born with a finite supply of eggs, limiting their reproductive years. Doctors have sought ways of extending the fertility of women, especially as many wait later in life to begin having children.

The research, led by Jonathan Tilly of Mass. General and appearing in the journal Nature Medicine, opens the door to the possibility of taking tissue from a woman’s ovaries, harvesting stem cells from that tissue, and then creating eggs.

But scientists not involved with the Mass. General research said such an approach -- if it is even possible -- sits far in the future and will require considerably more work. Several scientists said Tilly, who co-founded a company focused on developing novel infertility treatments, had not yet made a convincing case that the stem cells he discovered can yield viable eggs, a critical first step.

Tilly has been a lightning rod in the field of fertility medicine since 2004, when he challenged the orthodoxy that women do not produce new eggs. In a research paper published that year, Tilly laid the foundation for the findings reported yesterday.

“There was a lot of backlash. It wasn’t surprising, given the magnitude of the paradigm shift that was being proposed -- this was one of the fundamental beliefs in our field,” Tilly said. “The subsequent eight years have been a long haul.”

In his new study, Tilly extended research by Chinese scientists published in 2009. He developed a technique that allowed scientists to sift out rare stem cells within the ovaries of mice that were tagged and implanted into the ovaries of normal mice. In the mouse ovaries, the stem cells produced eggs, which were removed and fertilized in a laboratory dish. They developed into embryos, although scientists did not use the embryos to produce mice.

Tilly and his team then wanted to know if such cells existed in humans, too.

The research team obtained ovarian tissue removed from young women undergoing sex change operations in Japan and performed the same experiment they’d done with the mouse ovaries. Much to their excitement, they discovered the rare, egg-producing cells in humans.

In later experiments, the human stem cells were used to produce cells that appeared to be eggs. In part because of ethical limitations, researchers were not able to show that the eggs could be used to create human embryos.

Tilly said that he has patented the stem cells and licensed the technology to OvaScience, the startup he co-founded.

Outside researchers described the findings as intriguing and provocative but also raised many questions. Scientists said it was still far from certain that the eggs created in the experiments could be used to produce babies. And they expressed concern that the findings could falsely inflate the hopes of women struggling with infertility.

Dr. David Keefe, chairman of obstetrics and gynecology at New York University Langone Medical Center, said he and other clinicians who see patients would like more than anything to have greater options for women to overcome infertility. But he said the Mass. General researcher had a history of leaping ahead from basic research findings to suggest clinical possibilities.

“Those of us who take care of patients are extremely protective of their hopes,” Keefe said. He noted that a few years ago, he saw half-a-dozen patients who wanted to delay their fertility decisions because of earlier research at Mass. General.

Even if the new findings are immediately replicated in labs around the world, Keefe said, “it’s so far from being clinical that it’s predatory to not be circumspect about it. Humility is an absolute requirement in this field. You’re dealing with people’s hopes and dreams.”

A 2005 study led by Tilly and done in mice suggested bone marrow transplants might offer a way to restore fertility. A year later, a separate group of Harvard researchers showed that this was unlikely to be true. Tilly himself no longer believes this is a way to restore fertility.

“The big difference in that work, now in retrospect, is these non-ovarian sources [of stem cells] don’t appear to do the job,” he said.

Tilly’s work in the past has divided researchers and failed to persuade many in the field that his interpretations are correct.

Teresa Woodruff, a professor of obstetrics and gynecology at the Feinberg School of Medicine at Northwestern University said she had already drawn up a chart of the claims made in the paper, the evidence to support those claims, and the questions they raise. Still, she said, “I do think he’s pushing the envelope in a way that does push all of us to think more broadly.”

Evelyn Telfer, a cell biologist at the University of Edinburgh, who criticized some of Tilly’s earlier work, said she is excited about the new findings. Tilly said that next month, he will fly to Scotland to begin a collaboration with Telfer.

“What he’s saying is we can get these cells,” Telfer said, “and I think it’s pretty convincing.”

The new paper doesn’t offer evidence that such stem cells are active in the ovary, supplying eggs during a woman’s lifetime. But the powerful cells could provide new insights into the important and poorly understood process in biology of egg-formation and allow scientists to look for drugs that might increase the activities of these stem cells, in order to overcome fertility problems.

Skeptics and supporters agreed on one thing: much work lies ahead.

“That’s science,” said Hugh Clarke, a professor in the department of obstetrics and gynecology at McGill University. “Of course, dogma should be challenged, but we shouldn’t assume dogma has been overturned based on a single report.”

Qatari students to present research on stem cells

By JoanneRUSSELL25

Research on the potential of stem cells in preventing ovarian cancer, obesity-related diseases and other serious illnesses affecting people in Qatar and the region is to be presented by three Qatari graduate students at the Qatar International Conference on Stem Cell Science and Policy next week.
The conference is organised by Qatar Foundation for Education, Science and Community Development (QF) and James A Baker III Institute for Public Policy.
It will provide an international platform to discuss the latest discoveries in stem cell research and collaborate on new therapeutic approaches for the use of stem cells, within an acceptable ethics, cultural and religious framework.
The students are part of QF’s Qatar Science Leadership Programme (QSLP), and their participation in the conference is considered an important part of their training. 
With more than 400 registered participants, including key ethicists and scientists in stem cell research, the conference provides students invaluable opportunities for exchanging knowledge and building relationships with top figures and leading regional and international institutions in the field.
QSLP, aims to equip rising Qatari generations for leading roles in the country’s scientific and research endeavours, with stem cell research as a national priority.
Qatari QSLP trainee and PhD student from Paris XI University, Dr Hamda al-Thawadi, will present at the conference a poster about her research on ovarian cancer.
She explained that this is an important area specifically for Qatar, as there is a high prevalence of thrombotic diseases which affect patients with cancer.
“My project will help in detecting a powerful tool for the assessment of thrombosis risk factors in patients with cancer as well as healthy individuals, which should help develop preventative measures,” she said.
Dr Halema Alfarsi, another student on QSLP’s scientific track, is also presenting her research on ovarian cancer at the conference. Her work explores the potential application of stem cells in making cells and tissues for medical therapies.
She pointed out that currently, donated tissues and organs are often used to replace those that are diseased or destroyed. Stem cells offer a viable source of replacement cells to treat diseases and can potentially reduce the morbidity and mortality for those awaiting transplants for Parkinson’s disease, spinal cord injury, severe burns, diabetes and arthritis.
“In Qatar we have many cases of cancer, diabetes, heart disease and arthritis. Stem cells offer hope for effective treatment or perhaps even reversal of the disease,” added Dr Alfarsi.
The recently published Heba al-Siddiqi, another QSLP student, will present her research on preventing chronic obesity-related diseases through tissue engineering and organ regeneration. This research was recently featured in the leading international scientific journal Nature.
“Tackling obesity-related diseases such as coronary heart disease and type 2 diabetes through developing stem cell technology is very important as these diseases are increasingly common in Qatar,” observed al-Siddiqi.
“I am excited about the potential of creating cell-based therapies to treat and prevent chronic diseases in Qatar for future generations,” she added.
The three student presenters will be joined at the conference by their fellow QSLP members, Sarah Ali Abdulla and Abeer al-Shammari. 
Abdulla, who is pursuing her PhD in stem cell science and neuroscience at the University of Cambridge, will serve as master of ceremonies over the conference’s four days.
“The Qatar conference on stem cells supports our students’ scientific development by including them in the country’s stem cell research community and connecting them with leading figures in the field. We hope it will inspire young people in Qatar and the region to pursue studies in stem cell science,” said QF’s head of Research Training and Development, Dr Ayman Bassil.
The Qatar International Conference on Stem Cell Science and Policy opens on February 27, 2012 at the Qatar National Convention Centre.

Makucell(TM) Announces Key Scientific Presentations and Launch of a Large, Multicenter Use Study of Asymmtate(TM)

By JoanneRUSSELL25

To: HEALTH, MEDICAL AND NATIONAL EDITORS

SCOTTSDALE, Ariz., Feb. 21, 2012 /PRNewswire-USNewswire/ -- Makucell, Inc., a new life science company that utilizes an innovative proprietary regenerative medicine technology to address aging skin, hair and nail conditions, has presented important pre-clinical and clinical information on its proprietary molecule, Asymmtate, at the 36th Annual Hawaii Dermatology Seminar, Waikoloa, Hawaii. Asymmtate(TM) is the active key ingredient in Makucell's new topical skin care line Renewnt(TM) (pronounced "Re-new-int").

Asymmtate(TM) is a selective modulator of the Wnt (pronounced "wint") signaling pathway that encourages optimal signaling to stimulate skin stem cells to replenish themselves, keratinocytes, fibroblasts and other dermal cells, which produce collagen, elastic tissue, matrix and other substances to foster a more healthy, rejuvenated appearing skin. Renewnt(TM) will be available through aesthetic dermatology professionals in April 2012.

Mark Dahl, M.D. Makucell's, Vice President and Chief Medical Officer, presented the two scientific poster presentations. The presentation titles and conclusions are summarized below.

-- The Safety and Efficacy of Asymmtate - Asymmtate(TM) penetrates into human epidermis and dermis and remains active. Asymmtate in its cream vehicles is non-mutagenic, non-irritating, and non-sensitizing. -- Asymmtate(TM) Analog Mitigates Photoaging Effects of UVB in Mice - An analog of Asymmtate applied topically can mitigate the subsequent visible appearance of photoaging changes in mice after exposures of their skin to UVB.

In addition to the pre-clinical/clinical information presented this week, Makucell has initiated a 100 subject Use Study to evaluate the safety and efficacy of Renewnt(TM) for Hydration Day and Night Moisturizer in a real world setting. This four-week study will include 12 investigator sites across the U.S. "This large multicenter study is very important to validate aspects of clinical product performance of Asymmtate(TM) under real world conditions. The diverse geographical study sites will allow us to evaluate effects on unique skin types in different climates," said Lawrence A. Rheins, President and CEO of Makucell.

The innovative technology that resulted in the formulation of Renewnt was developed by distinguished research scientist Michael Kahn, Ph.D. and colleagues at the Eli & Edythe Broad Center for Stem Cell and Regenerative Medicine at the University of Southern California, Keck School of Medicine. "This is an exciting time for Makucell," said Makucell co-founder and inventor Michael Kahn, Ph.D. "This technology will be utilized for commercial topical applications to address the challenges of photoaging skin and other hair and nail conditions."

Scarred Hearts Healed After Heart Attack

By JoanneRUSSELL25

Heart-Attack Damage Heals After Stem Cell Treatment

Feb. 13, 2012 -- A new stem cell treatment resurrects dead, scarred heart muscle damaged by a recent heart attack.

The finding, just in time for Valentine's Day, is the clearest evidence yet that literally broken hearts can heal. All that's needed is a little help from one's own heart stem cells.

"We have been trying as doctors for centuries to find a treatment that actually reverses heart injury," Eduardo Marban, MD, PhD, tells WebMD. "That is what we seem to have been able to achieve in this small number of patients. If so, this could change the nature of medicine. We could go to the root of disease and cure it instead of just work around it."

Marban, director of the Cedars-Sinai Heart Institute in Los Angeles, led the study. He invented the "cardiosphere" culture technique used to create the stem cells and founded the company developing the treatment.

It's the first completed, controlled clinical trial showing that scarred heart tissue can be repaired. Earlier work in patients with heart failure, using different stem cells or bone-marrow stem cells, also showed that the heart can regenerate itself.

"These findings suggest that this therapeutic approach is feasible and has the potential to provide a treatment strategy for cardiac regeneration after [heart attack]," write University of Hong Kong researchers Chung-Wah Siu and Hung-Fat Tse. Their editorial accompanies the Marban report in the Feb. 14 advance online issue of The Lancet.

Heart Regenerates With Stem Cell Help

The stem cells don't do what people think they do, Marban says.

It's been thought that the stem cells multiply over and over again. In time, they were supposed to be turning themselves and their daughter cells into new, working heart muscle.

But the stem cells seem to be doing something much more amazing.

"For reasons we didn't initially know, they stimulate the heart to fix itself," Marban says. "The repair is from the heart itself and not from the cells we give them."

Exactly how the stem cells do this is a matter of "feverish research" in Marban's lab.

The phase I clinical trial enrolled 25 patients who had just had a heart attack. On average, each patient had lost a quarter of his heart muscle. MRI scans showed massive scars.

Eight patients got standard care. The other 17 received increasing infusions of what Marban calls stem cells. The cells were grown in the lab from tiny amounts of heart cells taken from the patients' own hearts via biopsy. Six to 12 weeks later, the cells were infused directly back into patients' hearts.

A year later, the mass of scar tissue in the treated patients' hearts got 42% smaller. And healthy heart muscle increased by 60%. No such regeneration was seen in the patients who got standard care.

Because all of the patients were doing relatively well, there was no dramatic difference in clinical outcome. However, treated patients had a bit better exercise endurance.

"This discovery challenges the conventional wisdom that, once established, cardiac scarring is permanent and that, once lost, healthy heart muscle cannot be restored," Marban and colleagues conclude.

Scientists grow brain cells from human skin

By JoanneRUSSELL25

LONDON: British scientists are claiming a breakthrough after creating brain tissue from human skin.

The researchers have for the first time generated a crucial type of brain cells in the laboratory by reprogramming skin cells.

They say it could speed up the hunt for new treatments for conditions such as Alzheimer's disease, epilepsy and stroke.

Advertisement: Story continues below

Until now it has only been possible to generate tissue from the cerebral cortex, the area of the brain where most serious neurological diseases occur, by using controversial embryonic stem cells, obtained by the destruction of an embryo. This has meant the supply of brain tissue available for research has been limited due to ethical concerns and limited availability.

Scientists at the University of Cambridge say that they have overcome this problem, showing for the first time that it is possible to re-program adult human skin cells so that they develop into neurons found in the cerebral cortex.

Initially, brain cells grown in this way could be used to help researchers gain a better understanding of how the brain develops and what goes wrong when it is affected by disease. They could also be used for screening new drug treatments.

Eventually, they hope the cells could be used to provide healthy tissue that can be implanted into patients to treat neurodegenerative diseases and brain damage.

Dr Rick Livesey, who led the research at the university's Gurdon Institute, said: ''The cerebral cortex makes up 75 per cent of the human brain. It is where all the important processes that make us human take place. It is, however, also the major place where disease can occur.

''We have been able to take reprogrammed skin cells so they develop into brain stem cells and then essentially replay brain development in the laboratory.

''We can study brain development and what goes wrong when it is affected by disease in a way we haven't been able to before. We see it as a major breakthrough in what will now be possible,'' said Dr Livesey, whose findings are published in the journal Nature Neuroscience.

The cerebral cortex is the part of the brain that is responsible for most of the high-level thought processes such as memory, language and consciousness.

Study shows cardiac stem cells outperform bone marrow stem cells in treating heart attacks

By JoanneRUSSELL25

A new study by collaborating researchers at the University of Miami Miller School of Medicine and L’Institut du Thorax in Nantes, France, indicates that stem cells derived from cardiac tissue are far more effective in repairing damage caused by a heart attack than therapies using stem cells taken from bone marrow. The study, published today in STEM CELLS Translational Medicine, suggests that human fetal cardiac-derived c-kit+ stem cells (CSCs) can be 30 times more potent than bone marrow mesenchymal stem cells (MSCs) for treating a heart attack.

Durham, NC (PRWEB) February 07, 2012

A new study by collaborating researchers at the University of Miami Miller School of Medicine and L’Institut du Thorax in Nantes, France, indicates that stem cells derived from cardiac tissue are far more effective in repairing damage caused by a heart attack than therapies using stem cells taken from bone marrow. The study, published today in STEM CELLS Translational Medicine, suggests that human fetal cardiac-derived c-kit+ stem cells (CSCs) can be 30 times more potent than bone marrow mesenchymal stem cells (MSCs) for treating a heart attack.

As both of these cell types are currently in clinical trials, these results are significant because they are the first direct comparison of their therapeutic capability in vivo, the researchers say.

“This research — showing that CSCs can be 30 times more potent than MSCs — is significant because it can impact the design of future clinical trials,” said Dr. Anthony Atala, director of the Wake Forest Institute of Regenerative Medicine and editor of STEM CELLS Translational Medicine. “The results from the study, one of a few to compare efficacy, have the potential to make the translation process more efficient, speeding the development of new effective therapies.”

The researchers conducted their study using mice models with induced acute myocardial infarction. The mice then received human fetal CSCs or either an equivalent (low dose) or ~30-fold greater number (high dose) of MSCs. Cells were injected immediately after the attack. A control group received PBS. The researchers performed additional experiments to address whether adult CSCs are as efficient as fetal CSCs. The fetal stem cells outperformed the adult-cultured CSCs, as expected; still, the researchers concluded that the latter were more potent than high-dose MSCs in treating a heart attack.

The animals were then evaluated at various intervals over a period of eight weeks. The results showed that the CSCs improved the left ventricle, which had been enlarged by the heart attack, plus lowered the ejection fraction. While the high doses of the MSCs showed similar results, the low-doses of MSCs had no effect.

“This study was motivated by the huge advances occurring in the translation of stem cell therapeutics for heart disease,” said Dr. Joshua Hare, senior author of the study and director of UM’s Interdisciplinary Stem Cell Institute. “While many candidate therapies are being considered there are few studies comparing relative efficacy. This study shows that tissue specific cardiac stem cells are highly potent, but that bone marrow stem cells are also efficacious. We hope these results will help guide future clinical trials of cell-based therapy for heart disease.”

In addition, said Dr. Behzad Oskouei of UM’s Interdisciplinary Stem Cell Institute, “All cell therapies studied improved myocardial contractility, but the CSCs preferentially reduced scar size and vascular afterload. Engraftment and trilineage [cardiomyocyte, vascular smooth muscle, endothelial cell] differentiation was also substantially greater with CSCs than with MSCs.”

“It is clear that CSCs are superior in this regard and have potential advantages over MSCs to promote repair following ischemic heart damage. Furthermore, they are effective at a surprisingly low-dose/efficacy ratio,” Dr. Oskouei noted. “These findings offer key new insights into the cellular characteristics underlying successful cell-based cardiac repair.”

“Wide-ranging applications for pluripotent stem cells”

By JoanneRUSSELL25

Many more diseases can be targeted, says expert

While applications of induced pluripotent stem cells in stem cell therapy may be limited to a few diseases, its applications in drug discovery are wide-ranging, and many more diseases can be targeted, Shinya Yamanaka, Director, Centre for iPS Cell Research and Application, Japan, has said.

The Japanese scientist, whose breakthrough was the creation of embryonic-like stem cells from adult skin cells, believes that the best chance for stem cell therapy lies in offering hope to those suffering from a few conditions, among them, macular disease, Type 1 Diabetes, and spinal cord injuries.

On the other hand, there were multiple possibilities with drug discovery for a range of diseases, and Prof. Yamanaka was hopeful that more scientists would continue to use iPS for studying this potential.

He currently serves as the Director of the Center for iPS Cell Research and Application and as Professor at the Institute for Frontier Medical Sciences at Kyoto University. He is also a Senior Investigator at the University of California, San Francisco (UCSF) - affiliated J. David Gladstone Institutes.

An invited speaker of the CellPress-TNQ India Distinguished Lectureship Series, co-sponsored by Cell Press and TNQ Books and Journals, Prof. Yamanaka spoke to a Chennai audience on Tuesday evening about those “immortal” cells, that he originally thought would take “forever” to create, but actually took only six years.

“My fixed vision for my research team was to re-programme adult cells to function like embryonic-like stem cells. I knew it could be done, but just didn't know how to do it,” Prof. Yamanaka said.

Embryonic stem cells are important because they are pluripotent, or possess the ability to differentiate into any other type of cell, and are capable of rapid proliferation. However, despite the immense possibilities of that, embryonic cells are a mixed blessing: there are issues with post-transplant rejection (since they cannot be used from a patient's own cells), and many countries of the world do not allow the use of human embryos.

Dr. Yamanaka's solution would scale these challenges if only he and his team could find a way to endow non-embryonic cells with those two key characteristics of embryonic stem cells.

In 2006, he and his team of young researchers — Yoshimi Tokuzawa, Kazutoshi Takahashi and Tomoko Ishisaka — were able to show that by introducing four factors into mouse skin cells, it was possible to generate ES-like mouse cells. The next year, they followed up that achievement, replicating the same strategy and converted human skin cells into iPS cells. “All we need is a small sample of skin (2-3millimetres) from the patient. This will be used to generate skin fibroblasts, and adding the factors, they can be converted to iPS cells. These cells can make any type of cell, including beating cardiac myocytes (heart cells), Prof.Yamanaka explained.

iPS cells hold out for humanity a lot of hope in curing diseases that have a single cell cause. Prominent among them are Lou Gehrig's Disease or Amyotrophic lateral sclerosis (ALS), also known as motor neuron disease. Motor neurons degenerate and die, and no effective treatment exists thus far. One reason is that there have not been good disease models for ALS in humans. It is difficult to get motor neuron from human patients and motor neurons cannot divide.

“Now, iPS cells can proliferate and can be differentiated to make motor neurons in large numbers,” he explained. Already a scientist in Japan has clarified motor neuron cells from iPS. “We are hoping that in the near future we would be able to evolve drug candidates that will be useful for ALS patients.” Treatment of spinal cord injuries using iPS cells has showed good results in mice and monkey specimens, and it is likely that in two or three years, scientists will be ready to start treatment for humans.

Toxicology, or drug side effects, is another area where iPS cells can be of use. Testing drug candidates directly on patients can be extremely dangerous. However, iPS cells can be differentiated into the requisite cell type, and the drugs tested on them for reactions. And yet, as wonderful as they may seem, iPS cells do have drawbacks, and there are multiple challenges to be faced before the technology can be applied to medicine. Are they equivalent and indistinguishable from ES cells? For a technology that has been around for only five years, the questions remain about safety. Also to derive patient-specific iPS cells, the process is time, and money-consuming, Prof. Yamanaka pointed out.

There are however, solutions in the offing, for the man who made the world's jaw drop with his discovery. One would be to create an iPS cell bank, where iPS cells could be created in advance from healthy volunteers donating peripheral blood, and skin fibroblasts, apart from frozen cord blood. The process of setting a rigorous quality control mechanism to select the best and safest iPS clones is on and would be complete within a year or two. “Many scientists are studying iPS cells across the world, and I'm optimistic that because of these efforts, we can overcome the challenges of iPS, and contribute to newer treatments for intractable diseases,” Prof. Yamanaka said.

N. Ram, Director, Kasturi & Sons Limited, introduced the speaker. Mariam Ram, managing director, TNQ India; and Emilie Marcus, executive editor, Cell Press, spoke.
