Endothelial cells residing in the coronary arteries can function as cardiac stem cells to produce new heart muscle tissue, Vanderbilt University investigators have discovered.
(Medical Xpress)—Like clues to a crime, specific molecules in the body can hint at exposure to toxins, infectious agents or even trauma, and so help doctors determine whether and how to treat a patient. ...
(Medical Xpress)—Watching films with stressful scenes can trigger changes to the heart's beating pattern, reports a new study published in the journal Circulation, Arrhythmia and Electrophysiology.
A new study in Nature challenges research data that form the scientific basis of clinical trials in which heart attack patients are injected with stem cells to try and regenerate damaged heart tissue.
(Medical Xpress)—To develop correctly, baby hearts need rhythm...even before they have blood to pump.
Mitochondria are the power plants of cells, manufacturing chemical fuel so a cell can perform its many tasks. These cellular power plants also are well known for their role in ridding the body of old or damaged cells.
Researchers have made a major advance in efforts to regenerate damaged hearts.
UCLA stem cell researchers have found for the first time a surprising and unexpected plasticity in the embryonic endothelium, the place where blood stem cells are made in early development.
(Medical Xpress) -- A blood test can predict whether patients are likely to die of a heart attack in the month after surgery, according to an international study involving thousands of patients.
Scientists at Duke University Medical Center have shown the ability to turn scar tissue that forms after a heart attack into heart muscle cells using a new process that eliminates the need for stem cell transplant.
Researchers at the Cedars-Sinai Heart Institute have found that injections of cardiac stem cells might help reverse heart damage caused by Duchenne muscular dystrophy, potentially resulting in a longer life expectancy for ...
In a study just published in the International Journal of Cardiology, researchers from the K.G. Jebsen Center for Exercise in Medicine – Cardiac Exercise Research Group (CERG) at the Norwegian University of Sci ...
Narine Sarvazyan and her team were trying to create universal-donor stem cells—cell transplants that the immune system would be less likely to reject—when something else caught her eye.
(Medical Xpress)—Cardiovascular disease remains the number one cause of death in the Western world, with heart failure representing the fastest-growing subclass over the past decade. The stage that precedes heart failure ...
The entire heart muscle in young children may hold untapped potential for regeneration, new research suggests.
