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. ...
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.
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.
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.
The entire heart muscle in young children may hold untapped potential for regeneration, new research suggests.
George Washington University (GW) researcher Narine Sarvazyan, Ph.D., has invented a new organ to help return blood flow from veins lacking functional valves. A rhythmically contracting cuff made of cardiac muscle cells surrounds ...
After a heart attack, there is often permanent damage to a portion of the heart. This happens, in part, because cardiac muscle cells are terminally differentiated and cannot proliferate after blood flow is blocked off to ...
Pure cardiac muscle cells, ready to transplant into a patient affected by heart disease.
Case Western Reserve researchers have identified a genetic factor that blocks the blood vessel inflammation that can lead to heart attacks, strokes and other potentially life-threatening events.
(Medical Xpress)—If the heart following a heart attack is not sufficiently supplied with blood, heart tissue dies. In adult humans, the ability to heal itself is hardly developed. Scientists from the Max ...
