When LSA senior Daniel Lee returned to the United States in December from a family trip to Italy feeling ill, he was rushed to the hospital where he received a life-threatening diagnosis — he had aplastic anemia, a disease that prevents bone marrow from producing red and white blood cells.

Upon hearing news of Lee’s dire need for a bone marrow transplant, students mobilized to encourage members of the campus community to donate marrow and raise awareness about the importance of joining the National Marrow Donor Registry.

As part of this effort, Sigma Kappa sorority members will work with DKMS Americas, a donor recruitment center, helping students, faculty and staff members register for the Be The Match Registry today from 10 a.m. to 4 p.m. in the Anderson AB Room in the Union.

LSA senior Samira Monavvari, Lee’s friend, has been working to promote today’s event via Facebook and has received more than 1,000 confirmed attendees. Monavvari said she hopes to be able to help someone else in need of a transplant, even if she doesn't find a match for Lee.

“The fact that Dan is going through this makes us want to donate to people who we don’t even know because it’s so hard seeing what he’s going through,” Monavvari said.

According to Monavvari, Lee is known jokingly by his friends as “the next Steve Jobs,” adding that he is extremely smart, driven and friendly.

“If you ask him what he wants to do, he’ll always say he wants to be known for something,” Monavvari said. “He is the kind of kid who gets along with everyone … that’s why (his diagnosis) has touched everyone so much.”

LSA junior Jessica Kaltz, a member of Sigma Kappa, started organizing the drive prior to Lee’s diagnosis. Kaltz worked with Christian Montgomery, a University alum and DKMS Americas employee, over the past few months to organize the registry at the University.

She wrote in an e-mail interview that she hopes that Lee’s story will inspire people to attend today’s event.

“When people hear about Dan’s story, I think they will see that by simply taking five minutes of their time by signing up to become a donor, they could possibly be the life-saving difference that Dan needs,” Kaltz wrote.

Montgomery explained that the process for joining the registry involves having potential donors fill out a short form and then submit a cheek swab to determine their tissue type.
Potential donors will then be added to the Be The Match Registry, a national list of potential bone marrow donors.

If the donor is contacted as a match and decides to continue with the process, he or she will be required to take a blood test in order to obtain the best match for the patient in need.

Between four and six weeks later, the donor will undergo a marrow extraction procedure or peripheral blood stem cell donation, depending on the patient’s condition. Contrary to popular belief, the donor typically does not experience significant pain, a common misconception about the two procedures, Montgomery said.

Montgomery is not only a DKMS employee, but also a bone marrow donor himself. In 2007, he registered at an event in the Diag, and in January 2008 he was contacted as a potential match for a 22-year-old female in New Jersey suffering from paroxysmal nocturnal hemoglobinuria, a rare blood disease.

Nicole Mausteller, the patient to whom Montgomery made his donation, said her disorder was discovered through blood work that was required as part of the process of becoming a dental assistant.

Montgomery donated through marrow extraction in May 2008, a procedure that he said left him a bit stiff and sore for a few days. After receiving a one-month, six-month and one-year update, Montgomery and Mausteller agreed to exchange contact information. They have been in contact since February 2010 and remain good friends.

“He’s my hero,” Mausteller said.

Bone marrow drive hopes to help student and save lives

Cambridge personalised medicines pioneer Horizon Discovery Ltd has landed another showpiece deal as part of a new super-cell consortium.

Business Weekly understands that the UK company stands to make a seven-figure haul over the lifetime of an EU-funded project aimed at understanding hES cell differentiation control.

Horizon provides research tools to support the development of personalised medicines. It has joined the EU-FP7 funded ‘4D-Cell-Fate’ consortium  whose aim is to shed light on how stem cell re-programming and differentiation is regulated at the epigenetic level.

As a member of the consortium, Horizon will generate cell-lines harbouring endogenous pathway reporter genes and labelled versions of specific epigenetic target proteins to study their function.

Commercialisation of the output of the programme will be governed by a consortium agreement defined by EU regulation.

4DCellFate brings together 12 groups from nine countries, including academics, research-intensive SMEs, and Pharma, each an international leader in its field, combining expertise in a wide range of cutting-edge technologies and scientific approaches.

The aim of the 4D CellFate project, which is currently funded for five years, is to establish an integrated approach to explore the structure and function of the large multi-protein epigenetic complexes that are involved in control of stem cell self-renewal, lineage commitment, and differentiation.

Horizon will use its proprietary virally-mediated gene-engineering technology, GENESIS™, to alter endogenous genes in hES cells (e.g. via tagging with GFP and HaloTag® technologies) with unprecedented accuracy and precision.

By gaining a greater insight into how Polycomb Repressive Complexes (PRCs), and Nucleosome Remodelling and Deacetylation complexes (NuRD) control stem cell differentiation, it is hoped that better methods will be identified to generate ethical sources of ‘iPS’ stem cells and direct the fate of stem cells into the many forms of specific tissue types that are needed for disease therapy.

Dr Chris Torrance, CSO of Horizon, said: “Generating stem cells and differentiated cell types with greater precision, definition and safety are key areas for delivering on the great promise that stem cell-based therapies could bring to many disease areas.

“Horizon’s gene targeting technology will play a key role in helping to dissect key biological pathways in the fate of stem cells as part of the 4D Cell Fate project. Through this process, new and important approaches to disease therapy will be determined.”

CEO Dr Darrin Disley added: “Our company has a commitment to active involvement in cutting-edge research with leading experts in translational fields, including bringing the power of rAAV-mediated gene targeting technology to the 4D Cell Fate project.”

About Pathfinder

Pathfinder is developing a novel cell-based therapy and has generated encouraging preclinical data in models of diabetes, renal disease, myocardial infarction, and critical limb ischemia, a severe form of peripheral vascular disease. Leveraging its internal discovery of Pathfinder Cells ("PCs") Pathfinder is pioneering a new field in regenerative medicine.

PCs are a newly identified mammalian cell type present in very low quantities in a variety of organs, including the kidney, liver, pancreas, lymph nodes, myometrium, bone marrow and blood. Early studies indicate that PCs stimulate regeneration of damaged tissues without the cells themselves being incorporated into the newly generated tissue. Based on testing to date, the cells appear to be "immune privileged," and their effects appear to be independent of the tissue source of PCs.

Pathfinder to Present at New York Stem Cell Summit

Stem cells harvested from a patient's own heart can be used to help repair muscle damaged during a heart attack, according to a preliminary study published online Monday in The Lancet. While it's too soon to know if the technique will help patients live longer, the study is the second small, promising study of cardiac stem cells in three months.

The new study involved 25 patients who had suffered very serious heart attacks; 24% of their heart's major pumping chamber had been replaced by scar tissue. One year later, doctors saw no improvement in those randomly assigned to get standard care. Among the 17 given stem cells, however, "we reversed about half the injury to the heart," said study author Eduardo Marban, director of the Cedars-Sinai Heart Institute in Los Angeles, in an e-mail. "We dissolved scar and replaced it with living heart muscle."

Warren Sherman, director of stem cell research and regenerative medicine at Columbia University Medical Center in New York, says the study was an important proof of the potential of stem cells - harvested from patients, grown in the lab, then injected back into patients' hearts.

Doctors don't yet know exactly how the stem cells reduce the size of the dead zone of scar tissue, says Kenneth Margulies, director of heart failure and transplant research at the University of Pennsylvania. And while the shrinking suggests that the stem cells are replacing dead cells with living ones, doctors can't definitely prove that without doing a biopsy of the actual cells, he says.

The new study's encouraging results seem to confirm the findings of another small study of heart stem cells, published in The Lancet in November, which also showed an improvement in heart-attack survivors who received the treatment, Margulies says. On the other hand, a third study, found no benefit from stem cells created from patients' own bone marrow.

Four stem-cell patients developed serious complications, compared to only one of the other patients, the study says. That suggests stem-cell therapy has a "satisfactory" safety record, but "is not risk-free," Margulies says.

The idea of regenerating heart tissue "was a pretty far-out idea" only 10 to 20 years ago, Margulies says. There's some evidence that heart tissue is capable of making some small repairs on its own, although not enough to help people who've had a heart attack.

Marban developed the process of growing heart stem cells while working at Johns Hopkins University, which has filed an application for a patent on the idea and licensed it to a company in which Marban has a financial interest. No money from that company was used to pay for the study, which was funded by Cedars-Sinai and the National Institutes of Health.

About 1.3 million Americans have a heart attack each year.

Stem Cells Help Regrow Heart Tissue

In the investigation, reported online in the journal PLoS ONE, the researchers isolated and characterized a novel type of cardiac stem cell from the heart tissue of middle-aged mice following a heart attack.

Then, in one experiment, they placed the cells in the culture dish and showed they had the ability to differentiate into cardiomyocytes, or "beating heart cells," as well as endothelial cells and smooth muscle cells, all of which make up the heart.

In another, they made copies, or "clones," of the cells and engrafted them in the tissue of other mice of the same genetic background who also had experienced heart attacks. The cells induced angiogenesis, or blood vessel growth, or differentiated, or specialized, into endothelial and smooth muscle cells, improving cardiac function.

"These findings are very exciting," said first author Jianqin Ye, PhD, MD, senior scientist at UCSF's Translational Cardiac Stem Cell Program. First, "we showed that we can isolate these cells from the heart of middle-aged animals, even after a heart attack." Second, he said, "we determined that we can return these cells to the animals to induce repair."

Importantly, the stem cells were identified and isolated in all four chambers of the heart, potentially making it possible to isolate them from patients' hearts by doing right ventricular biopsies, said Ye. This procedure is "the safest way of obtaining cells from the heart of live patients, and is relatively easy to perform," he said.

"The finding extends the current knowledge in the field of native cardiac progenitor cell therapy," said senior author Yerem Yeghiazarians, MD, director of UCSF's Translational Cardiac Stem Cell Program and an associate professor at the UCSF Division of Cardiology. "Most of the previous research has focused on a different subset of cardiac progenitor cells. These novel cardiac precursor cells appear to have great therapeutic potential."

The hope, he said, is that patients who have severe heart failure after a heart attack or have cardiomyopathy would be able to be treated with their own cardiac stem cells to improve the overall health and function of the heart. Because the cells would have come from the patients, themselves, there would be no concern of cell rejection after therapy.

The cells, known as Sca-1+ stem enriched in Islet (Isl-1) expressing cardiac precursors, play a major role in cardiac development. Until now, most of the research has focused on a different subset of cardiac progenitor, or early stage, cells known as, c-kit cells.

The Sca-1+ cells, like the c-kit cells, are located within a larger clump of cells called cardiospheres.

The UCSF researchers used special culture techniques and isolated Sca-1+ cells enriched in the Isl-1expressing cells, which are believed to be instrumental in the heart's development. Since Isl-1 is expressed in the cell nucleus, it has been difficult to isolate them but the new technique enriches for this cell population.

The findings suggest a potential treatment strategy, said Yeghiazarians. "Heart disease, including heart attack and heart failure, is the number one killer in advanced countries. It would be a huge advance if we could decrease repeat hospitalizations, improve the quality of life and increase survival." More studies are being planned to address these issues in the future.

An estimated 785,000 Americans will have a new heart attack this year, and 470,000 who will have a recurrent attack. Heart disease remains the number one killer in the United States, accounting for one out of every three deaths, according to the American Heart Association.

Medical costs of cardiovascular disease are projected to triple from $272.5 billion to $818.1 billion between now and 2030, according to a report published in the journal Circulation.

Stem cell study in mice offers hope for treating heart attack patients

WALLACE, NC (WECT) - Last year, thousands of people became aware of the serious medical condition of a six-year-old boy from Duplin County.

Wright Lanier passed away in mid-December, but there is no doubt he made an impact on the people who followed his medical condition on Facebook.

In 2010, Wright was diagnosed with a rare immune deficiency. Initially, doctors thought that he had lymphoma.

"The doctors, a lot of times, knew something was wrong, but in testing him nothing ever showed up," said Wright's mother, Dona Lanier. "He had a rare immune deficiency called XLP, which always looked like Lymphona in his body."

Because his condition was worsening, doctors decided Wright needed a bone marrow transplant, which is a procedure to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. The stem cells can develop into the red blood cells that carry oxygen through your body. The white cells are the ones that fight infections and the platelets help with blood clotting.

While the transplant actually worked, complications were too great, and Wright died just over a year after the surgery.

"The bone marrow transplant, according to the Cincinnati hospital and Chapel Hill, was a success, meaning it completely cured his XLP and MPS," explained Dona.  "Wright just unfortunately had a lot of complications as a result of the transplant that resulted in his passing."

"While bone marrow transplants are life saving procedures for a lot of children and adults, with diseases that used to be deadly, it can also be very dangerous, and unfortunately not everyone who has a bone marrow transplant survives," said Doctor David Hill, a Wilmington pediatrician.

Before Wright got sick, his mother was the school nurse at Penderlea School. Many of the teachers, including Donna Mintz, followed Wright's progress, and shortly after his death, plans were made to honor the young boy's short life.  A bone marrow registration drive will be held in his name in Wallace this weekend.

"If you knew Wright, you would be spoiled by the smile he had and he gave the best hugs in the world," said Mintz, a teacher and family friend. "And we want to do anything we can for the memory of Wright, to help his family."

"He had the biggest heart and he did live every day like it was his last," said Wright's mom. "He found joy in every single day".

The "Be The Match" registry drive will be held in honor of Wright Lanier this Saturday, from 11 a.m. - 4  p.m. in the Wallace Woman's Club building. Normally, there is a charge to be checked to see if you can become a donor, but this weekend, the fee has been waived.

There will also be other fundraising events taking place on Saturday, and all proceeds will go directly to the "Be The Match" registry.

Healthcare Prof:
According to a study published in the February issue of the STEM CELL Translational Medicine Journal , a world-first technique for generating adult stem cells (mesenchymal stem cells [MSCs]) has been developed by researchers at the University of Queensland. This new method can be used to repair bone and possibly other organs, and will considerably affect individuals suffering from a variety of serious diseases.

Professor Nicholas Fisk, who leads the collaborative study between the UQ Clinical Research Center (UQCCR) and the UQ's Australian Institute for Bioengineering and Nanotechnology (AIBN), explained:

"We used a small molecule to induce embryonic stem cells over a 10 day period, which is much faster than other studies reported in the literature.

The technique also worked on their less contentious counterparts, induced pluripotent stem cells.

To make the pluripotent mature stem cells useful in the clinic, they have to be told what type of cell they need to become (pre-differentiated), before being administered to an injured organ, or otherwise they could form tumors.

Because only small numbers of MSCs exist in the bone marrow, and harvesting bone marrow from a healthy donor is an invasive procedure, the ability to make our own MSCs in large number in the laboratory is an exciting step in the future widespread clinical use of MSCs.

We were able to show these new forms of stem cells exhibited all the characteristics of bone marrow stem cells and we are currently examining their bone repair capability."

Ernst Wolvetang, co-researcher on the study and AIBN Associate Professor, explained that the technique had overcome a considerable obstacle in the translation of stem cell-based therapy.

Wolvetang said: "We are very excited by this research, which has brought together stem cell researchers from two of the major UQ research hubs UQCCR and AIBN."

Favorable News From Advanced Cell Technology and StemCells Inc Boosts Optimism in Regenerative Medicine Industry

MARLBOROUGH, Mass.--(BUSINESS WIRE)--

Advanced Cell Technology, Inc. (“ACT”; OTCBB: ACTC), a leader in the field of regenerative medicine, announced today that the Wills Eye Institute in Philadelphia has received institutional review board (IRB) approval as a site for the company’s Phase I/II clinical trial for Stargardt’s Macular Dystrophy (SMD), a form of juvenile macular degeneration, using human embryonic stem cell (hESC)-derived retinal pigment epithelial (RPE) cells. Earlier this year, the Company also announced that the IRB at Wills Eye Institute had approved the participation of the institution as a site for ACT’s clinical trial for dry age-related macular degeneration (dry AMD).

“We thank Wills Eye Institute once more for providing their IRB and their invaluable contribution to our macular degeneration studies,” said Gary Rabin, ACT’s chairman and CEO. “We are very happy that we can now report that Wills Eye Institute has been approved as a clinical trial site for both our SMD and dry AMD clinical trials. Ranked as one of the best ophthalmology hospitals in the country by U.S. News & World Report, the Wills Eye Institute is a truly world-class institution. Our team is eagerly anticipating working with Dr. Carl Regillo, a renowned retinal surgeon and director of clinical retina research at Wills Eye Institute, as well as a professor of ophthalmology at Thomas Jefferson University, along with the rest of his team as we move forward with these ground-breaking trials.”

The Phase I/II trial for SMD is a prospective, open-label study designed to determine the safety and tolerability of the hESC-derived RPE cells following sub-retinal transplantation into patients with SMD. The trial will ultimately enroll 12 patients, with cohorts of three patients each in an ascending dosage format. Preliminary results relating to both early safety and biological function for the first two patients in the U.S., one SMD patient and one dry AMD patient, were recently reported in The Lancet.

Specific patient enrollment for both trials at the Wills Eye Institute will be determined in the near future. Further information about patient eligibility for the SMD study and the concurrent study on dry AMD is also available on http://www.clinicaltrials.gov; ClinicalTrials.gov Identifiers: NCT01345006 and NCT01344993.

About Stargardt's Disease

Stargardt’s disease or Stargardt’s Macular Dystrophy is a genetic disease that causes progressive vision loss, usually starting in children between 10 to 20 years of age. Eventually, blindness results from photoreceptor loss associated with degeneration in the pigmented layer of the retina, called the retinal pigment epithelium.

About hESC-derived RPE Cells

The retinal pigment epithelium (RPE) is a highly specialized tissue located between the choroids and the neural retina. RPE cells support, protect and provide nutrition for the light-sensitive photoreceptors. Human embryonic stem cells differentiate into any cell type, including RPE cells, and have a similar expression of RPE-specific genes compared to human RPE cells and demonstrate the full transition from the hESC state.

Advanced Cell Technology Announces Approval of Wills Eye Institute as Additional Site for Stem Cell Clinical Trial for ...

A new study at Johns Hopkins University has shown that stem cells from patients' own cardiac tissue can be used to heal scarred tissue after a heart attack. This is certainly exciting news considering heart failure is still the No. 1 cause of death in men and women.

The study included 25 heart attack victims, 17 of whom got the stem cell treatment. Those patients saw a 50% reduction in cardiac scar tissue after one year, while the eight control patients saw no improvement.

The procedure involves removing a tiny portion of heart tissue through a needle, cultivating the stem cells from that tissue, and reinserting them in a second minimally invasive procedure, according to Bloomberg.

"If we can regenerate the whole heart, then the patient would be completely normal," said Eduardo Marban, director of Cedars-Sinai Heart Institute who was the study's lead author. "We haven't fulfilled that yet, but we've gotten rid of half of the injury, and that's a good start."

Neuralstem Announces Closing of $5.2-Million Registered Direct Offering

SAN FRANCISCO -- Stem cells grown from patients' own cardiac tissue can heal damage once thought to be permanent after a heart attack, according to a study that suggests the experimental approach may one day help stave off heart failure.

In a trial of 25 heart-attack patients, 17 who got the stem cell treatment showed a 50 percent reduction in cardiac scar tissue compared with no improvement for the eight who received standard care. The results were published Tuesday in the medical journal Lancet.

The study, by researchers from Cedars-Sinai Heart Institute in Los Angeles and Johns Hopkins University in Baltimore, tested the approach in patients who recently suffered a heart attack, with the goal that repairing the damage might help stave off failure. While patients getting the stem cells showed no more improvement in heart function than those who didn't get the experimental therapy, the theory is that new tissue regenerated by the stem cells can strengthen the heart, said Eduardo Marban, the study's lead author and director of Cedars-Sinai Heart Institute.

The stem cells were implanted within five weeks after patients suffering heart attacks. Doctors removed heart tissue, about the size of half a raisin, using a minimally invasive procedure that involved a thin needle threaded through the veins. After cultivating the stem cells from the tissue, doctors reinserted 12.5 million to 25 million cells using a second minimally invasive procedure.

A year after the procedure, six patients in the stem cell group had serious side effects.

While the main goal of the trial was to examine safety, the decrease in scar tissue in those treated merits a larger study that focuses on broader clinical outcomes, researchers said.

"If we can regenerate the whole heart, then the patient would be completely normal," Dr. Marban said. "We haven't fulfilled that yet, but we've gotten rid of half of the injury, and that's a good start."

Heart's stem cells used to mend attack damage

February 15, 2012, 12:06 AM EST

By Ryan Flinn

(Adds comment from researcher in 13th paragraph.)

Feb. 14 (Bloomberg) -- Stem cells grown from patients’ own cardiac tissue can heal damage once thought to be permanent after a heart attack, according to a study that suggests the experimental approach may one day help stave off heart failure.

In a trial of 25 heart-attack patients, 17 who got the stem cell treatment showed a 50 percent reduction in cardiac scar tissue compared with no improvement for the eight who received standard care. The results, from the first of three sets of clinical trials generally needed for regulatory approval, were published today in the medical journal Lancet.

“The findings in this paper are encouraging,” Deepak Srivastava, director of the San Francisco-based Gladstone Institute of Cardiovascular Disease, said in an interview. “There’s a dire need for new therapies for people with heart failure, it’s still the No. 1 cause of death in men and women.”

The study, by researchers from Cedars-Sinai Heart Institute in Los Angeles and Johns Hopkins University in Baltimore, tested the approach in patients who recently suffered a heart attack, with the goal that repairing the damage might help stave off failure. While patients getting the stem cells showed no more improvement in heart function than those who didn’t get the experimental therapy, the theory is that new tissue regenerated by the stem cells can strengthen the heart, said Eduardo Marban, the study’s lead author.

“What our trial was designed to do is to reverse the injury once it’s happened,” said Marban, director of Cedars- Sinai Heart Institute. “The quantitative outcome that we had in this paper is to shift patients from a high-risk group to a low- risk group.”

Minimally Invasive

The stem cells were implanted within five weeks after patients suffering heart attacks. Doctors removed heart tissue, about the size of half a raisin, using a minimally invasive procedure that involved a thin needle threaded through the veins. After cultivating the stem cells from the tissue, doctors reinserted them using a second minimally invasive procedure. Patients got 12.5 million cells to 25 million cells.

A year after the procedure, six patients in the stem cell group had serious side effects, including a heart attack, chest pain, a coronary bypass, implantation of a defibrillator, and two other events unrelated to the heart. One of patient’s side effects were possibly linked to the treatment, the study found.

While the main goal of the trial was to examine the safety of the procedure, the decrease in scar tissue in those treated merits a larger study that focuses on broader clinical outcomes, researchers said in the paper.

Heart Regeneration

“If we can regenerate the whole heart, then the patient would be completely normal,” Marban said. “We haven’t fulfilled that yet, but we’ve gotten rid of half of the injury, and that’s a good start.”

While the study resulted in patients having an increase in muscle mass and a shrinkage of scar size, the amount of blood flowing out of the heart, or the ejection fraction, wasn’t different between the control group and stem-cell therapy group. The measurement is important because poor blood flow deprives the body of oxygen and nutrients it needs to function properly, Srivastava said.

“The patients don’t have a functional benefit in this study,” said Srivastava, who wasn’t not involved in the trial.

The technology is being developed by closely held Capricor Inc., which will further test it in 200 patients for the second of three trials typically required for regulatory approval. Marban is a founder of the Los Angeles-based company and chairman of its scientific advisory board. His wife, Linda Marban, is also a founder and chief executive officer.

“We’d like to study patients who are much sicker and see if we can actually spare them early death, or the need for a heart transplant, or a device,” Eduardo Marban said.

Scarred Hearts Can Be Mended With Stem Cell Therapy

Stem cells are proving themselves beneficial once again after scientists used the controversial building blocks to resurrect dead, scarred heart muscle damaged by recent heart attack.

Results from a Cedars-Sinai Heart Institute clinical trial show that treating heart attack patients with an infusion of their own heart-derived cells helps damaged hearts re-grow healthy heart muscle.

Reporting in The Lancet medical journal, the researchers said this is the clearest evidence yet that broken hearts can heal. All that is 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, and lead author of the study, told 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 invented the “cardiosphere” culture technique used to create the stem cells and founded the company developing the treatment.

“These findings suggest that this therapeutic approach is feasible and has the potential to provide a treatment strategy for cardiac regeneration after [heart attack],” wrote University of Hong Kong researchers Chung-Wah Siu and Hung-Fat Tse in an accompanying editorial of Marban’s paper.

The British Heart Foundation told James Gallagher of BBC News that this could “be great news for heart attack patients” in the future.

A heart attack occurs when the heart is starved of oxygen, such as when a clot is blocking the blood flow to the organ. As the heart heals, the dead muscle is replaced by scar tissue, which does not beat like heart muscle. This in turn reduces the hearts ability to pump blood around the body.

Doctors have long been searching for ways to regenerate damaged heart muscle, and now, it seems heart stem cells are the answer. And the Cedars-Sinai trial was designed to test the safety of using stem cells taken from a heart attack patient’s own heart.

The researchers found that one year after receiving the treatment, scar size was reduced from 24 percent to 12 percent of the heart in patients treated with heart stem cells. Patients in the control group, who did not receive stem cells, did not experience a reduction in their heart attack scar tissues.

“While the primary goal of our study was to verify safety, we also looked for evidence that the treatment might dissolve scar and re-grow lost heart muscle,” Marban said in a statement. “This has never been accomplished before, despite a decade of cell therapy trials for patients with heart attacks. Now we have done it. The effects are substantial, and surprisingly larger in humans than they were in animal tests.”

“These results signal an approaching paradigm shift in the care of heart attack patients,” said Shlomo Melmed, MD, dean of the Cedars-Sinai medical faculty and the Helene A. and Philip E. Hixon Chair in Investigative Medicine. “In the past, all we could do was to try to minimize heart damage by promptly opening up an occluded artery. Now, this study shows there is a regenerative therapy that may actually reverse the damage caused by a heart attack.”

Marban cautioned that stem cells do not do what people generally think they do. The general idea has been that stem cells multiply over and over again, and, in time, they turn themselves and their daughter cells into new, working heart muscle.

But Marban said the stem cells are actually doing something more amazing.

“For reasons we didn’t initially know, they stimulate the heart to fix itself,” he told Daniel J. DeNoon of WebMD. “The repair is from the heart itself and not from the cells we give them.”

Exactly how the stem cells invigorate the heart to do this was a matter of “feverish research” in the lab.

The CArdiosphere-Derived aUtologous stem CElls to reverse ventricUlar dySfunction (CADUCEUS) clinical trial was part of a Phase I study approved by the US Food and Drug Administration (FDA) and supported by the National Heart, Lung, and Blood Institute.

Marban used 25 volunteer patients who were of an average age of 53 and had recently suffered a heart attack that left them with damaged heart muscle. Each patient underwent extensive imaging scans so doctors could pinpoint the exact location and severity of the scars. Patients were treated at Cedars-Sinai in LA and at Johns Hopkins Hospital in Baltimore.

Eight of the 25 patients served as a control group, receiving conventional medical treatment. The other 17 patients who were randomized to receive the stem cell treatments underwent a minimally invasive biopsy, under local anesthesia. Using a catheter inserted through a vein in the neck, doctors removed a small sample of heart tissue, about half the size of a raisin. The heart tissue was then taken to the lab at Cedars-Sinai and cultured and multiplied the cells using specially developed tools.

The doctors then took the multiplied heart-derived cells — roughly 12 million to 25 million of them per patient — and reintroduced them into the patient’s coronary arteries during another minimally invasive catheter procedure.

The process used in the trial was developed earlier by Marban when he was on the faculty at Johns Hopkins. Johns Hopkins has filed for a patent on the intellectual property and has licensed it to a company in which Marban has a financial interest. However, no funds from that company were used to support the clinical study. All funding was derived from the National Institutes of Health and Cedars-Sinai Medical Center.

This study followed another in which doctors reported using cells taken from the heart to heal the heart. That trial reported in November 2011 that cells could be used to heal the hearts of heart failure patients who were having heart bypass surgery.

And another trial is about to get underway in Europe, which will be the largest ever for stem cell therapy in heart attack patients.

The BAMI trial will inject 3,000 heart attack patients with stem cells taken from their bone marrow within five days of the heart attack.

Marban said despite the heart’s ability to re-grow heart muscle with the help of heart stem cells, they found no increase in a significant measure of the heart’s ability to pump — the left ventricle ejection fraction: the percentage of blood pumped out of the left ventricle.

Professor Anthony Mathur, a coordinating researcher for the upcoming BAMI trial, said that even if the Marban trial found an increase in ejection fraction then it would be the source of much debate. As it was a proof-of-concept study, with a small group of patients, “proving it is safe and feasible is all you can ask.”

“The findings would be very interesting, but obviously they need further clarification and evidence,” he told BBC News.

“It’s the first time these scientists’ potentially exciting work has been carried out in humans, and the results are very encouraging,” Professor Jeremy Pearson, associate medical director at the British Heart Foundation, told BBC News.

“These cells have been proven to form heart muscle in a petri dish but now they seem to be doing the same thing when injected back into the heart as part of an apparently safe procedure,” he added. “It’s early days, and this research will certainly need following up, but it could be great news for heart attack patients who face the debilitating symptoms of heart failure.”

Stem Cells Regrow Healthy Heart Muscle In Heart Attack Patients

Click here to listen to this podcast

Valentine's Day can lead to plenty of broken hearts. But for cardiac wounds that time alone won't heal, science has made some major advances. When it comes to heart attack, for example, a big development is emerging from a tiny source. Stem cells are coming of age. 

Stem cells, harvested from a patient's own bone marrow, have been heralded as a potential quick fix for damaged heart tissue. But can these progenitor cells actually work to heal massive muscle damage?

A new review of 33 studies assessed data from more than 1,700 heart attack patients. The review researchers found that those patients treated with stem cells—in addition to the standard care of angioplasty—had stronger tickers for years to come than those who had not gotten stem cell therapy. The review article is published in The Cochrane Library. [David Clifford et al., Stem Cell Treatment for Acute Myocardial Infarction, link to come]

It's too early to say whether those with stem cell treatments will live longer, according to the new analysis. But for affairs of the heart, it's more evidence that good things can come in very small packages.

—Katherine Harmon

Patient / Public: Healthcare Prof:
A systematic review of the evidence so far suggests stem cells derived from bone marrow moderately improves heart function after a heart attack. But the authors say larger trials are needed before we can devise guidelines for therapy practice, or draw conclusions about the long-term benefit of the treatment, such as whether it extends life.

The review, about to be published in the Cochrane Library, updates one done in 2008 that reviewed 13 trials; the new one takes into account another 20 more recent trials. Even though these later trials had longer follow ups, it was still not possible to draw firm conclusions about the long term benefits.

Lead author Enca Martin-Rendon, of the Stem Cell Research laboratory, NHS Blood and Transplant at the John Radcliffe Hospital in Oxford, UK, told the press that they found it hard to compare the 33 studies because they used so many different approaches:

"Larger trials with standardised treatment procedures would help us to know whether this treatment is really effective," said Martin-Rendon.

In order to pump blood around the body, the heart also needs its own constant supply of blood. If this supply is cut off by a blocked artery, it can cause a heart attack and damage the muscle tissue in the affected part of the heart, causing the cells to start dying, a process known as necrosis.

In the days and weeks after a heart attack, the necrosis can spread, eventually leaving a large part of the heart muscle unable to perform the job of contracting and pumping as well as it ought to. This increases the risk of further heart problems.

Stem cells are precursor cells that have the potential to mature into any cell in the body, including heart muscle cells. For this review, the researchers looked only at treatments that use stem cells derived from bone marrow. At present, such treatments are only available at centres that do research.

Another recently published study described a treatment that used stem cells derived from the patient's own heart tissue to repair heart attack damage.

For the review, Martin-Rendon and colleagues pooled data on a total of 1,765 patients from 33 trials. All the patients had already undergone the conventional treatment, angioplasty, where a balloon is inflated in the blocked artery to open it up and restore blood flow.

They concluded that stem cell therapy using bone marrow-derived stem cells (BMSCs) can result in a moderate long-term improvement in heart function, that lasts for up to 5 years. But there was not enough data to enable them to say anything firm about the effect on survival rates.

Martin-Rendon said:

"This new treatment may lead to moderate improvement in heart function over standard treatments," adding that:

"Stem cell therapy may also reduce the number of patients who later die or suffer from heart failure, but currently there is a lack of statistically significant evidence based on the small number of patients treated so far."

The authors said it was still to early to compile guidelines for standard practice, and further work would be needed before anyone can do this. For instance, more information is needed to establish cell dosage, the timing of transplantation and how best to measure heart function.

One large trial, called BAMI, is already under way. The European Society of Cardiology for Stem Cells and Cardiac Repair is conducting the trial, which is funded by the European Union Seventh Framework Programme for Research and Innovation (EU FP7-BAMI).

Anthony Mathur, a co-author of this latest Cochrane review, and principal investigator of the BAMI trial, said:

''The BAMI trial will be the largest stem cell therapy trial in patients who have suffered heart attacks and will test whether this treatment prolongs the life of these patients."
