Findings on heart muscle growth could lead to novel approaches for treating heart failure in children BOSTON, Jan. 10, 2013 /PRNewswire-USNewswire/ -- Researchers at Boston Children's Hospital have found, for the first time that young humans (infants, children and adolescents) are capable of generating new heart muscle cells. These findings refute the long-held belief that the human heart grows after birth exclusively by enlargement of existing cells, and raise the possibility that...

When a young athlete dies unexpectedly on the basketball court or the football field, it's both shocking and tragic. Now Stanford University School of Medicine researchers have, for the first time, identified the molecular basis for a condition called hypertrophic cardiomyopathy that is the most common cause for this type of sudden cardiac death. To do so, the Stanford scientists created induced pluripotent stem cells, or iPS cells, from the skin cells of 10 members of a family with a...

-Heart cells from patients with inherited heart muscle disease can now be studied in a petri dish without risk to patients, including the possibility of testing new treatments -Experiments performed on the cells show that the heart cell model matches that of the clinical features of arrhythmogenic right ventricular cardiomyopathy (ARVC), an inherited heart muscle disease associated with sudden cardiac death -Landmark study published in European Heart Journal, a top ranking international...

Transplanted heart cells, grown from stem cells, electrically couple and beat in sync with heart's own muscle Researchers have made a major advance in efforts to regenerate damaged hearts. Grafts of human cardiac muscle cells, grown from embryonic stem cells, coupled electrically and contracted synchronously with host muscle following transplantation in guinea pig hearts. The grafts also reduced the incidence of arrhythmias (irregular heart rhythms) in a guinea pig model of...

[ Watch the Video: Researchers Find Surprises In Heart Muscle Cells ] Connie K. Ho for redOrbit.com — Your Universe Online Scientists from the University of California, Los Angeles (UCLA) recently discovered that the embryonic endothelium, where the blood stem cells are produced in early development, has more plasticity than originally anticipated. The findings are exciting as the embryonic blood vessels can even produce beating heart muscles. The researchers suggest that the...

ST. LOUIS, July 31, 2012 /PRNewswire/ -- Sigma-Aldrich® Corporation (Nasdaq: SIAL) today announced that Sigma Life Science, its innovative biological products and services research business, has signed an agreement with Axiogenesis to market mouse induced pluripotent stem (iPS) cell-derived cardiomyocytes and smooth muscle cells. In contrast to short-lived, tissue-derived primary cells that predominate preclinical drug discovery and cardiotoxicity screens, Sigma Life Science and...

Research on diabetic mice reveals heart benefits of increased fatty acids released during exercise A detailed study of heart muscle function in mice has uncovered evidence to explain why exercise is beneficial for heart function in type 2 diabetes. The research team, led by scientists at the Johns Hopkins University School of Medicine, found that greater amounts of fatty acids used by the heart during stressful conditions like exercise can counteract the detrimental effects of excess...

Connie K. Ho for redOrbit.com Pumping vigorously night and day, the heart is clearly one of the most important organs in the human body. It is also one of the most delicate parts of the body. As such, news regarding heart-related diseases is beneficial to both doctors and patients. University of Michigan (UM) researchers recently reported the discovery of a new method that could produce cardiac muscle patches from stem cells. The innovative process was created at UM´s Center for...

Discovery could be used to help engineer artificial tissue A study led by researchers from McGill University provides new insights into the structure of muscle tissue in the heart — a finding that promises to contribute to the study of heart diseases and to the engineering of artificial heart tissue. The research, published in the Proceedings of the National Academy of Sciences (PNAS), reveals that the muscle fibers in the heart wall are locally arranged in a special "minimal...
