New strategy for mending broken hearts?
By mimicking the way embryonic stem cells develop into heart muscle in a lab, Duke University bioengineers believe they have taken an important first step toward growing a living "heart patch" to repair heart tissue damaged by disease. view more (2009-10-12)
Team reveals molecular mechanism underlying a form of diabetes
By investigating a rare and severe form of diabetes in children, University of Iowa researchers have discovered a new molecular mechanism that regulates specialized pancreatic cells and insulin secretion. view more (2009-09-09)
Stem cells not the only way to fix a broken heart
Researchers appear to have a new way to fix a broken heart. They have devised a method to coax heart muscle cells into reentering the cell cycle, allowing the differentiated adult cells to divide and regenerate healthy heart tissue after a heart attack. view more (2009-07-24)
Injection reverses heart-attack damage
Injured heart tissue normally can't regrow, but researchers at Children's Hospital Boston have now laid the groundwork for regenerating heart tissue after a heart attack, in patients with heart failure, or in children with congenital heart defects. view more (2009-07-24)
Early heart attack therapy with bone marrow extract improves cardiac function
A UCSF study for the treatment of heart failure after heart attack found that the extract derived from bone marrow cells is as effective as therapy using bone marrow stem cells for improving cardiac function, decreasing the formation of scar tissue and improving cardiac pumping capacity after heart attack. view more (2009-06-30)
Novel biomarkers in heart failure
Several new biomarkers have been recently described in Heart Failure (HF) syndrome either in stable chronic patients as in the settings of acute decompensation. view more (2009-06-01)
Gladstone scientists identify key factors in heart cell creation
Scientists at the Gladstone Institute of Cardiovascular Disease have identified for the first time key genetic factors that drive the process of generating new heart cells. view more (2009-04-27)
Researchers at UH Explore use of Fat Cells as Heart Attack Therapy
For those of us trained to read nutrition labels, conventional wisdom tells us that fat isn't good for the heart. But a team of University of Houston researchers has set out to use fat cells to beef up heart muscles damaged by heart attack - and they're using an out-of-this-world device to do it. view more (2008-10-28)
Study provides insight on a common heart rhythm disorder
University of Iowa researchers and colleagues in France have identified a gene variant that causes a potentially fatal human heart rhythm disorder called sinus node disease. view more (2008-10-08)
Cardiac cell transplant studies show promise in cardiac tissue repair
Two studies published in the current issue of CELL TRANSPLANTATION (17:6) examine the efficacy of transplanting bone marrow cells (BMCs) for the repair of heart tissue. view more (2008-09-04)
New source of heart stem cells discovered
Researchers at Children's Hospital Boston are continuing to document the heart's earliest origins. Now, they have pinpointed a new, previously unrecognized group of stem cells that give rise to cardiomyocytes, or heart muscle cells. view more (2008-06-23)
UCLA stem cell researchers create heart and blood cells from reprogrammed skin cells
Stem cell researchers at UCLA were able to grow functioning cardiac cells using mouse skin cells that had been reprogrammed into cells with the same unlimited properties as embryonic stem cells. view more (2008-04-30)
Heart stem cell scientist to honor pioneering woman scientist in keynote speech
Professor Christine Mummery, one of the world's leading heart stem cell experts, will later today (9 April) honour the memory of Dame Anne McLaren in the keynote lecture of the inaugural UK National Stem Cell Network Science Meeting in Edinburgh. view more (2008-04-10)
Top 10 research advances include studies on genetics and stem cell research, stents
Several new studies on genetics and stem cell research, along with studies that continue to debate the use of stents to clear coronary artery blockages are among the top research advances in heart disease and stroke for 2007, said Daniel W. Jones, M.D., president of the American Heart Association. view more (2007-12-21)
Genes identified that protect against heart damage from chemotherapy
A series of genes that protect cells from the powerful, common chemotherapeutic agent doxorubicin has been identified by researchers working to understand how the drug also can destroy the heart. view more (2007-12-04)
Human derived stem cells can repair rat hearts damaged by heart attack
When human heart muscle cells derived from embryonic stem cells are implanted into a rat after a heart attack, they can help rebuild the animal's heart muscle and improve function of the organ, scientists report in the September issue of Nature Biotechnology. view more (2007-08-27)
Geron Demonstrates hESC-derived cardiomyocytes improve heart function after myocardial infarction
Geron Corporation (Nasdaq: GERN) today reported its scientists and collaborators have demonstrated that human embryonic stem cell (hESC)-derived cardiomyocytes improve heart function when transplanted after myocardial infarction. view more (2007-08-27)
System to analyze beating heart stem cells could lead to heart attack treatments
New research at the University of Nottingham, funded by the Biotechnology and Biological Sciences Research Council (BBSRC), is paving the way for techniques that use stem cells to repair the damage caused by heart attacks. view more (2007-07-30)
Using stem cells to help heart attack victims
New research at The University of Nottingham is paving the way for techniques that use stem cells to repair the damage caused by heart attacks. view more (2007-07-30)
Can heart tissue be regenerated?
When human hearts are injured, as during a heart attack, healthy tissue normally can't regrow. Researchers now demonstrate in rats that a sponge-like patch, soaked in a compound called periostin and placed over the injury, can not only get heart cells to begin dividing and making copies of themselves again, but also improves heart function. view more (2007-07-18)
