Israeli Scientists Reprogram Skin Cells into Beating Heart Tissue: Stem Cell Research Pays Off – Video

By raymumme

24-05-2012 09:53 For the first time ever, scientists have transformed normal skin cells into healthy beating heart tissue. Researchers based in Haifa in Israel, say they hope that the breakthrough will one day lead to new treatments for patients suffering from heart failure. Head of Research Professor Lior Gepstein "We were able to demonstrate the ability to take skin cells from very sick patients with significant heart failure, heart disease, and show that cells, skin cells from these patients can be eventually differentiated to become healthy heart cells in the dish. So one can take skin cells from a very sick individual, who has very sick heart cells, to reprogram them to become induced pluripotent stem cells and then make heart cells that are healthy, that are young and resemble heart cells at the day that the patient was born." At the moment, people with severe heart failure have to rely on mechanical devices or hope for a transplant. However, by studying stem cells from various sources for more than a decade, researchers are hoping to capitalise on their ability to transform stem cells into a wide variety of other kinds of cell. Head of Research Professor Lior Gepstein "These cells can be transplanted into hearts of animals, survive and function in synchrony with existing heart tissue. This study open the road, hopefully, to future clinical trials, in a decade or so, that will test the ability of such heart cells to repair the patient's own heart," There may be a lot to do before ...

State awards stem cell grants to medical researchers

By JoanneRUSSELL25

SACRAMENTO California's stem cell agency today approved two grants to UC Davis Health System researchers for their innovative work in regenerative medicine.

Kyriacos A. Athanasiou, distinguished professor of orthopaedic surgery and professor and chair of biomedical engineering, and the Child Family Professor of Engineering at UC Davis, is investigating the use of skin-derived stem cells to heal cartilage injuries and debilitating conditions of the knee such as osteoarthritis.

W. Douglas Boyd, professor of surgery, plans to further refine a novel approach to treating cardiovascular injuries suffered during a heart attack by using stem cells and a tissue-like scaffold to repair cardiac damage.

The pair received individual grants totaling approximately $6.6 million from the California Institute for Regenerative Medicine's (CIRM) governing board.

Athanasiou's and Boyd's multi-year grants were among the proposals submitted to CIRM for its third round of Early Translational Awards, which are intended to enable clinical therapies to be developed more rapidly.

"Both of these scientists are conducting exciting research that could have far-reaching implications in health care," said Jan Nolta, director of the UC Davis Institute for Regenerative Cures and the university's stem cell program director. "Dr. Athanasiou is bioengineering new cartilage that could have the same physiological integrity as the cartilage a person is born with. Dr. Boyd is developing a treatment that uses a paper-thin patch embedded with stem cells to harness their regenerative powers to repair damaged heart muscle."

Boyd, who's a pioneering cardiothoracic surgeon, pointed out in his CIRM proposal that heart disease is the nation's number-one cause of death and disability. An estimated 16.3 million Americans over the age of 20 suffer from coronary heart disease, which in 2007 accounted for an estimated 1 in 6 deaths in the U.S. Boyd plans to use bone-marrow derived stem cells -- known as mesenchymal stem cells -- in combination with a bioengineered framework known as an extracellular matrix, to regenerate damaged heart tissue, block heart disease and restore cardiac function, something currently not possible except in cases of a complete and very invasive heart transplant.

An expert in biomedical engineering, Athanasiou is focusing on developing a cellular therapy using stem cells created from an individual's own skin -- known as autologous skin-derived stem cells -- which have shown great promise in animal models. He plans to use the new funding to conduct extensive toxicology and durability tests to determine the technique's long-term safety and efficacy. Such tests are among the many steps needed to advance toward human clinical trials.

Cartilage is the slippery tissue that covers the ends of bones in joints, allowing bones to glide over each other and absorbing the shock of movement. Cartilage defects from injuries and lifelong wear and tear can eventually degenerate into osteoarthritis. According to the National Institute of Arthritis and Musculoskeletal and Skin Diseases, osteoarthritis is the most common form of arthritis and affects an estimated 27 million Americans over the age of 25.

"For anyone suffering from osteoarthritis or other debilitating cartilage conditions, Dr. Athanasiou's goal of using stem cells to regenerate new tissue could have enormous quality-of-life and economic benefits," said Nolta, who is the recipient of a prior translational grant from CIRM to develop potential therapies for Huntington's disease . "Dr. Boyd's work is equally promising because he's using a bioengineered structure to encourage cardiac tissue repair, which could have important benefits in the treatment of heart disease."

How damaged hearts could be healed by growing stem cells

By LizaAVILA

By Jenny Hope

PUBLISHED: 18:09 EST, 22 May 2012 | UPDATED: 01:35 EST, 23 May 2012

Scientists claim they can rejuvenate broken hearts using skin cells that have been turned into heart muscle cells.

New research opens up the prospect of reprogramming cells taken from heart failure patients that would not be rejected by their bodies.

It is the first time that stem cells taken from the skin of elderly and diseased patients - who are most likely to need such treatment - have been transformed into heart cells.

New developments: The research opens up the prospect of reprogramming cells taken from heart failure patients that would not be rejected by their bodies

Previously skin cells taken from young and healthy people have been transformed into heart muscle cells.

But researchers from Israel warn that clinical trials could be a decade away, as more work in the laboratory and major investment are needed.

The research is the latest advance in stem cell therapy where the intention is to infused repair cells directly into the scarred heart muscle of patients suffering debilitating symptoms such as breathlessness and fatigue.

Pluristem trial finds stem cells improve cardiac dysfunction

By daniellenierenberg

Pluristem Therapeutics Ltd. (Nasdaq:PSTI; DAX: PJT: PLTR) today reported that the cardiac function in a diabetic-induced diastolic dysfunction in animals improved following PLacental eXpanded (PLX cells) administration.

The study was conducted as part of the European Commission's Seventh Framework Program (FP7) in collaboration with Prof. Doctor Carsten Tschope and his staff at the Charite Universitaetsmedizin Berlin, Berlin-Bradenburg Center for Regenerative Therapies (BCRT), Berlin, Germany.

Dr. Tschope said, "Currently, there are limited treatment options for diastolic dysfunction and even fewer options for diabetic induced diastolic dysfunction. This study holds promise that PLX cells might be able to inhibit diabetic induced diastolic dysfunction progression as well as possibly repair the existing damage, hypotheses that will be further explored in future studies."

Diabetes was induced in thirty-six mice resulting in the development of diastolic heart failure. After seven days, the animals received either PLX cells from two separate batches or placebo (12 subjects in each of the three groups). Ten mice were not treated (controls).

After three weeks, several cardiac parameters were assessed and found to be significantly improved following the treatment with PLX cells. Important measurements included the cardiac ejection fraction and the left ventricular (LV) relaxation time constant, believed to be the best index of LV diastolic function and a determination of the stiffness of the ventricle. Cardiac ejection fraction improved 19%, the left ventricular relaxation time constant fell 16% and stiffness of the ventricle fell 19%.

Administration of either batch of PLX cells also resulted in a significant anti-inflammatory effect.

Pluristem chairman and CEO Zami Alberman said, "As we demonstrated last week with the announcement that our cells successfully treated the seven year old patient suffering from aplastic bone marrow disease, our strategy is to develop a minimally invasive cell therapy solution that can be used to treat a wide range of life-threatening diseases. Our initial testing of a treatment for diastolic heart disease opens a new potential indication where our cells can be used and potentially positions Pluristem as a "first-line of defense" for diastolic dysfunction."

Pluristem's share price jumped 5.6% in pre-market trading on Nasdaq to $3.01, giving a market cap of $126.33 million. The share rose 10.6% on the TASE today to NIS 11.50.

Biz Beat: Making stem cells "available to the masses"

By LizaAVILA

Mike Ivey writes on all matters money in the spirit of Capital Times founder William T. Evjue, who believed that the concentration of wealth in the U.S. is not healthy for the Democracy.

When UW-Madison's James Thomson in 1998 became the first scientist to grow human embryonic stem cells in a lab, it generated tremendous excitement about the medical possibilities.

Thomson tried to downplay the breakthrough but talk spread about cures for Alzheimers or Parkinsons disease, growing livers for cirrhosis suffers or producing healthy heart cells for cardiac patients.

The miracle cures have been slow in coming, however. Scientists can replicate healthy nerve cells in a Petri dish but havent found a way to replace defective spinal cells in ALS victims, for example.

In many ways, were still at the first steps,Anita Bhattacharyya, a senior scientist in the stem cell program at the UW's Waisman Center, told a business group Tuesday.

Butproducing stem cells for others to use is proving one of Madisons more promising new business ventures. Pharmaceutical companies in particular are using stem cells to test drugs before launching into expensive further testing.

Were making these cells available to the masses, says Chris Parker, chief technology officer at Cellular Dynamics International.

Launched by Thomson -- and backed with $100 million from a local investor group -- Cellular Dynamics International was lauded recently by MIT as one of the 50 most important companies in the world

Since its founding in 2005, the company now counts 107 employees at it offices in University Research Park and is continuing to grow.

Im hiring right now, Parker joked toa lunch crowd of the Wisconsin Technology Council Tuesday.

Stanford Group Publishes Fluidigm-Based Method for Gene Expression Profiling of Single Stem Cells

By raymumme

By Ben Butkus

Stanford University researchers have published a method for using Fluidigm's digital PCR platform to conduct single-cell, real-time PCR to compare gene expression patterns of single cells.

The protocol is indicative of the increased use of Fluidigm's products for single-cell biology, an application area that the company has been heavily promoting over the past year.

In addition, the method may provide a powerful tool for understanding gene expression and differentiation in induced pluripotent stem cells and human embryonic stem cells for regenerative medicine, the researchers said.

In a paper published last week in Nature Protocols, researchers led by Joseph Wu, associate professor of medicine, cardiology, and radiology at Stanford University School of Medicine, described how they used Fluidigm's BioMark HD platform and Dynamic Array chips to analyze gene expression profiles of single iPSCs or hESCs approximately 11 hours after collection.

The team decided to publish the method after using it to conduct a study published last March in the Journal of Clinical Investigation that demonstrated how single-cell transcriptional profiling revealed heterogeneity in human iPSCs. "A lot of people asked us after that JCI paper how we exactly do this, so we decided to write a detailed protocol," Wu told PCR Insider.

Wu and colleagues began using Fluidigm's platform through the laboratory of fellow Stanford scientist Stephen Quake, a co-founder of the company and a co-author on the recent Nature Protocols paper.

According to Veronica Sanchez-Freire, a postdoc in Wu's lab and also a co-author on the paper, the group needed a tool to compare gene expression between individual cells in single colonies of iPSCs or hESCs with high sensitivity using a limiting amount of sample.

"We were interested in seeing how different gene expression could be in the cell depending on its position in the colony," Sanchez-Freire said. "We are looking at these iPS cells from different cell types and donors, and we always compare them to [human embryonic] stem cells, the gold standard but we also wanted to see how similar they are [to each other]."

Most traditional gene expression studies, using, for example, quantitative real-time PCR, extract RNA from a large population of cells for downstream expression analysis. "And we saw that when you do that, iPS cells and stem cells are very similar," Sanchez-Freire said. "But when you go to the single-cell level, we saw how the iPS cells are more heterogeneous than the ES cells."

Expert wants central bank for cord blood

By JoanneRUSSELL25

A nodal public stem-cell bank in India is the need of the hour if blood cancer and thalassaemia patients are to benefit from stem-cell therapy, according to an expert.

We need an indigenous inventory of 30,000 units of umbilical cord-blood stem-cells, which would enable seven out of 10 patients seeking stem-cell transplant to find a ready match off the shelves, said P. Srinivasan, a pioneer in public cord-blood banking in the country, addressing members of the Ladies Study Group of the Indian Chamber of Commerce on Friday.

Cord blood, also called placental blood, is the blood remaining in the umbilical cord and placenta following childbirth after the cord is cut, and is routinely discarded with the placenta and umbilical cord as biological waste.

A rich source of stem cells, cord blood can be used to treat over 80 diseases, including certain cancers like leukaemia, breast cancer, blood disorders like thalassaemia major and autoimmune disorders like lupus, multiple sclerosis, Crohns Disease and rheumatoid arthritis.

Early clinical studies suggest these can even help avert corneal degeneration and restore vision in cases of blindness, help restore proper cardiac function to heart attack sufferers and improve movement in patients with spinal cord injury.

Since stem-cell matching is highly ethnicity dependent, the chances of an Indian finding a perfect match in a foreign country is a lot less compared to a resource pool of locally-donated units, the former resource person for WHO, now the chairman and managing trustee of Jeevan Blood Bank and Research Centre in Chennai, added.

Even if someone finds a match abroad, the cost of shipping the bag of matching cord blood could be as high as $40,000, as against the Rs 30,000 required for processing and storing one unit indigenously.

Srinivasan felt reaching the critical mass of 30,000 cord-blood units wasnt a big deal, given the fact that 20 million babies are born in India every year.

Purnima Dutta, the president of Ladies Study Group, agreed that raising awareness on the need to donate umbilical cord blood was the key.

As women and responsible citizens, the onus is on us to spread the word and encourage young couples to come forward and donate cord blood to ensure we can achieve this desired public-bank inventory which can save valuable lives, she said.

Dexmedetomidine for Maintaining Sedation

During prolonged mechanical ventilation, sedation with midazolam or propofol is associated with serious adverse effects. Jakob and colleagues assessed the efficacy of dexmedetomidinean 2-agonist sedativecompared with either midazolam or propofol in 2 multicenter randomized trials that involved 998 patients expected to require more than 24 hours' mechanical ventilation. Among the authors' findings was that dexmedetomidine was not inferior to midazolam or propofol in maintaining light to moderate sedation or in reducing total ventilation duration compared with midazolam. However, dexmedetomidine was associated with more adverse events. In an editorial, Wunsch discusses the costs and benefits of sedative options for critically ill patients undergoing mechanical ventilation.

Epinephrine is widely used in resuscitation of patients with out-of-hospital cardiac arrest; however, its effectiveness is not established. Hagihara and colleagues analyzed registry data from 417188 patients with out-of-hospital cardiac arrest to assess the relationship between prehospital epinephrine use and mortality and functional status among survivors. The authors report that prehospital epinephrine use was associated with increased return of spontaneous circulation before hospital arrival but decreased the likelihood of survival at 1 month or survival with good functional status. In an editorial, Callaway discusses the evidence that epinephrine use during cardiopulmonary resuscitation may not improve patient-oriented outcomes.

In a randomized trial of 159 patients undergoing living-related kidney transplants, Tan and colleagues found that compared with conventional antiinterleukin 2 receptor antibodybased therapy, a regimen that involved infusion of autologous mesenchymal stem cells was associated with a lower incidence of acute rejection and better renal function at 1 year.

The use of anesthesiologists or nurse anesthetists to administer procedural sedation during outpatient endoscopies increases costs. In a retrospective analysis of claims data from 1.1 million Medicare beneficiaries and 5.5 million commercially insured patients, Liu and colleagues found that utilization of anesthesia services during upper endoscopies and colonoscopies increased from approximately 14% in 2003 to more than 30% in 2009. The majority of anesthesia services were provided to low-risk patients and varied across geographic regions. In an editorial, Fleisher discusses factors that may contribute to increased use of anesthesia services for patients undergoing endoscopy procedures.

Pluristem reports success in stem cell heart attack treatment

By Sykes24Tracey

Pluristem Therapeutics Ltd. (Nasdaq:PSTI; DAX: PJT: PLTR) today announced that its PLacental eXpanded (PLX) cells improve several parameters in acute myocardial infarction (heart attacks) in animals. The preclinical trial was conducted at the Center for Regenerative Therapies in Germany.

The trial included 20 mice, which were given induced heart attacks. Half the mice were then given either PLX cells, and the other half were given a cell-free medium as a control. Five other mice underwent a sham (placebo) operation. After four weeks, the mice underwent an ECG, and were then killed for a physical examination of their hearts. The mice which received PLX had improved cardiac muscle function compared with the control group.

Study leader Prof. Christof Stamm said, "As a cardiac surgeon, the unique ability demonstrated by Pluristem's PLX cells for the treatment of heart disease is very exciting." He added, "PLX cells showed promising results in the AMI studies."

Pluristem chairman and CEO Zami Aberman said, "These results demonstrate the potential benefits of our cells for use in the treatment of ischemic heart disease, a multi-billion dollar annual market, and one in which many pharmaceutical companies are constantly looking to provide patients with innovative and effective solutions. In addition to moving ahead with our AMI trial, we look forward to continuing to work on finding cell therapy solutions for numerous debilitating diseases."

An article in the New England Journal of Medicine states that 624,000 patients suffer an acute myocardial infarction annually in the US, a number that will most likely increase with the rising prevalence of obesity, diabetes and the aging of the population.

Pluristem's share price rose 5.1% by mid-afternoon on the TASE today to NIS 8.50, after closing at $2.15 on Nasdaq yesterday, giving a market cap of $95 million. The share is up 6.5% in premarket trading on Nasdaq today.

SAN FRANCISCO, CAMarch 15, 2012Gladstone Institutes Senior Investigator Deepak Srivastava, MD has won the prestigious 2012 Abraham White Scientific Achievement Award from The George Washington University. Dr. Srivastava, who directs cardiac and stem cell research at Gladstone will share the award with Dr. Luigina Romani, professor of microbiology at the University of Perugia.

Dr. Srivastava is being recognized for his findings concerning how the protein thymosin beta 4 is vital to protect and repair cells that become damaged in a heart attackpointing the way to its potential use in treating cardiac disease. His research has shown that thymosin beta 4 is not only critical to the development of a heart, but that it also prevents heart cells from dyingwhile stimulating new blood vessels to form.

"Dr. Srivastava's pioneering studies and scientific contributions have significantly advanced our understanding of the role of thymosin beta 4 in the development and function of the human heart," said Allan Goldstein, PhD, professor and emeritus chairman of The George Washington University. "His studies have provided the scientific foundation for the potential use of thymosin beta 4 to treat heart attacks and other heart diseases."

Dr. Srivastava, who joined Gladstone in 2005, uses modern genetic and stem cell technologies to identify the molecular events that instruct progenitor cells to become cardiac cellsand subsequently fashion a functioning heart. In addition to his research with thymosin beta 4, Dr. Srivastava and his lab have successfully reprogrammed connective tissue in the heart directly into beating heart cellsa process that may help regenerate damaged heart muscle.

"Heart disease is the leading cause of death in the United States and basic research in this field is vital to identifying and understanding the causes of human heart disease," said Dr. Srivastava, who is also a professor of pediatrics, biochemistry and biophysics at the University of California, San Francisco (UCSF), with which Gladstone is affiliated. "I am honored to receive this award and hope our efforts ultimately lead to important new treatments for patients with heart conditions."

George Washington University presents the Abraham White Scientific Achievement Award annually to honor individuals who have made unique contributions to science and medicine. Notable past recipients include Nobel laureates Bengt Samuelsson, MD, Julius Axelrod, MD, Michael Brown, MD, Joseph Goldstein, MD and Tim Hunt, PhD in addition to a number of other distinguished scientists. The award will be presented today at a special ceremony in Washington D.C.

"We are delighted that George Washington University has acknowledged Dr. Srivastava's exceptional achievements in the field of cardiovascular research," said Gladstone President R. Sanders Williams, MD. "He richly deserves this recognition due to the creativity and innovation evident in his workand because of its potential to benefit the millions of individuals suffering from cardiac disorders."

Before joining Gladstone, Dr. Srivastava was a professor in the department of pediatrics and molecular biology at the University of Texas Southwestern (UTSW) Medical Center in Dallas. He has received numerous honors and awards, including endowed chairs at UTSW and UCSF, as well as election to the American Society for Clinical Investigation, the Society for Pediatric Research, the American Academy of Arts and Sciences and the American Association for the Advancement of Science.

The paper's lead author, Kenneth Chien from Harvard University in the USA explains:

Until now, clinical trials have been based on heart attacks, chronic heart failure as well as dilated cardiomyopathy, but regardless of the fact that regenerative therapies that are based on various non-cardiac cell types seem to be safe, their efficacy has not yet been tested in a clinical trial.

However, possible new targets and treatment strategies are now emerging due to recent progress in cardiac stem cell research and regenerative biology.

Scientists used to think that the heart only has a minimal capacity for self-renewal and saw no prospect in reversing the loss of healthy heart muscle and function. This perception has been altered because of recent findings, such as the discovery of several distinct embryonic progenitor cell types of which some are found in the heart.

A certain number of these cells can be activated in people with cardiac injuries and are now targeted by scientists to develop novel cardiac regenerative therapeutics either by delivery of the cells, or by new methods that activate expansion and conversion of functioning heart cells.

For instance, clinical studies conducted a short while ago demonstrated that scar formation following a heart attack can be reduced by taking cells from the patient's own heart tissue. Even though it remains uncertain whether the delivered cells are indeed stem cells, these studies nevertheless demonstrate that this is a small, educational step towards the goal of utilizing the heart's potential for self-healing.

Baxter Initiates Phase III Adult Stem Cell Clinical Trial for Chronic Cardiac Condition

By Dr. Matthew Watson

Study Aims to Deliver Adult’s Own Cells As Treatment for Chronic Myocardial Ischemia

DEERFIELD, Ill.--(BUSINESS WIRE)--Baxter International Inc. (NYSE:BAX) announced today that it has initiated a phase III pivotal clinical trial to evaluate the efficacy and safety of adult autologous (an individual’s own) CD34+ stem cells to increase exercise capacity in patients with chronic myocardial ischemia (CMI).

Chronic myocardial ischemia (CMI) is one of the most severe forms of coronary artery disease, causing significant long-term damage to the heart muscle and disability to the patient. It is often diagnosed based on symptoms of severe, refractory angina, which is severe chest discomfort that does not respond to conventional medical management or surgical interventions.

“The prospect of using a person’s own adult stem cells to restore and repair blood flow in CMI is a very exciting concept based on a biological regenerative approach,” said Norbert Riedel, Ph.D., Baxter’s chief science and innovation officer. “The goals of this phase III trial are aligned with Baxter’s overall mission to develop life-saving and life-sustaining therapies and it will help us determine if the therapy can make a meaningful difference for CMI patients.”

The trial will enroll approximately 450 patients across 50 clinical sites in the United States, who will be randomized to one of three arms: treatment with their own autologous CD34+ stem cells, treatment with placebo (control), or unblinded standard of care. The primary objective is to evaluate the efficacy of treatment with CD34+ stem cells to improve the functional capacity of patients with CMI, as measured by a change in total exercise capacity at 12 months following treatment. Secondary objectives include reduced frequency of angina episodes at 12 months after treatment and the safety of targeted delivery of the cells.

After stem cell mobilization, apheresis (collecting the cells from the body) and cell processing, participants will receive CD34+ stem cells or placebo in a single treatment via 10 intramyocardial injections into targeted areas of the heart tissue. Efficacy will be measured by a change in total exercise capacity during the first year following treatment and safety data will be collected for two years. Stem cell processing will be conducted in GMP facilities in the United States by Progenitor Cell Therapy (PCT), a subsidiary of NeoStem, Inc. To learn more or enroll, visit http://www.renewstudy.com or http://www.clinicaltrials.gov.

This trial is being initiated based on the phase II data, which indicated that injections of patients’ own CD34+ stem cells may improve exercise capacity and reduce reports of angina episodes in patients with chronic, severe refractory angina.

“The phase II trial provided evidence that this strategy, leveraging the body’s own natural repair mechanisms, can improve exercise capacity and reduce chest pain, the first time these endpoints have been achieved in a population of patients who have exhausted conventional treatment options,” said Douglas Losordo, MD, vice president of new therapeutic development at Baxter.

CD34+ cells, which are blood-forming stem cells derived from bone marrow, are comprised of endothelial progenitor cells (EPCs), which develop into new blood vessels. Previous preclinical studies investigating these cells have shown an increase in capillary density and improved cardiac function in models of myocardial ischemia.

Eggs made from stem cells could treat more than just fertility

By Dr. Matthew Watson

In a new study, Harvard researchers say they have found stem cells in women that can be used to grow new eggs. Not surprisingly, this has raised much discussion about whether a woman’s biological clock can be stopped – why worry about running out of eggs if you can just make new ones whenever you  need them?

The work described in the paper, published online Sunday by the journal Nature Medicine, is still a long way from being useful to women in need of fertility treatments. And many scientists remain skeptical that these ovarian stem cells really can mature into healthy eggs.

But as long as we’re in the pie-in-the-sky realm, let’s consider another way that the ability to grow an abundant supply of eggs would be helpful: to make human embryonic stem cell lines that would be perfectly matched to patients.

This was a hot area of research in the middle of the last decade. While many scientists studied stem cells made from embryos that were no longer needed for fertility treatments, a smaller group was pursuing a derivation method called somatic cell nuclear transfer, or SCNT. It’s better known as “therapeutic cloning.”

Here’s the idea: You take an egg and remove all the DNA in the cell nucleus. Then you replace it with DNA from a patient. You give the egg an electric shock so it starts dividing and growing into an early-stage embryo.

But instead of implanting this embryo into a uterus and producing a baby that’s a genetic copy of another person, you would use it to make a line of human embryonic stem cells. Then you can use those stem cells to make replacement parts – new cardiac cells for patients who suffered heart attacks, for instance, or nerve cells that would replace those lost after a spinal cord injury. In theory, the new cells would work perfectly because they’d be a perfect genetic match. This is the vision of regenerative medicine.

For a few months back in 2005, it looked like this vision was on the verge of reality. South Korean researcher Hwang Woo Suk published a landmark paper in the journal Science in which he claimed to have made 11 lines of stem cells that were genetic matches to patients with Type 1 diabetes, spinal cord injuries and the so-called Bubble Boy disease. Scientists rejoiced, as did doctors and patients. But a few months later, Hwang was accused of faking the results. The study was retracted, and Hwang was prosecuted for embezzling research money and violating ethics laws.

Since then, researchers at Oregon Health & Sciences University have managed to clone monkey embryos in order to create embryonic stem cells. But in a 2007 study in the journal Nature, they said they had to use 304 eggs to make just two viable cell lines.

It’s hard to imagine how scientists would ever get their hands on 304 human eggs, especially since they generally aren’t allowed to pay women who might be willing to donate eggs for research purposes. It’s also not clear that a few hundred eggs would be enough to guarantee at least one line of stem cells. South Korean investigators eventually discovered that Hwang used 2,236 eggs in his studies that failed to produce a single embryo.

This is one of the major reasons why SCNT studies fell by the wayside. (For more on that, read this story from 2006.) But if there were a relatively simple way to grow hundreds – or thousands – of eggs in the lab, some scientists are confident they could create stem cells through therapeutic cloning.

If so, that would make the research at Harvard relevant to a whole lot of people besides women who hear their biological clocks ticking.

A summary of the Nature Medicine study is online here.

Stem Cell Study in Mice Offers Hope for Treating Heart Attack Patients – Video

By Dr. Matthew Watson

08-02-2012 01:41 A UCSF stem cell study conducted in mice suggests a novel strategy for treating damaged cardiac tissue in patients following a heart attack. The approach potentially could improve cardiac function, minimize scar size, lead to the development of new blood vessels -- and avoid the risk of tissue rejection. 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 the mice who had had the heart attacks. The cells induced angiogenesis, or blood vessel growth, or differentiated, or specialized, into endothelial and smooth muscle cells, improving cardiac function. Because the cells were transplanted back into the mice from which they originated, the body did not reject them.
