(Medical Xpress)—To develop correctly, baby hearts need rhythm...even before they have blood to pump.
The immune system plays an important role in the heart's response to injury. But until recently, confusing data made it difficult to distinguish the immune factors that encourage the heart to heal following ...
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.
The promise of repairing damaged hearts through regenerative medicine—infusing stem cells into the heart in the hope that these cells will replace worn out or damaged tissue—has yet to meet with clinical success. But ...
(Medical Xpress)—A painstaking effort to create a biocompatible patch to heal infant hearts is paying off at Rice University and Texas Children's Hospital.
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 have discovered a new function for a protein that protects cells during injury and could eventually translate into treatment for conditions ranging from cardiovascular disease to Alzheimer's.
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.
Johns Hopkins scientists have developed a simplified, cheaper, all-purpose method they say can be used by scientists around the globe to more safely turn blood cells into heart cells. The method is virus-free and produces ...
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 ...
So many Americans experience dangerous fluctuations in heartbeat that about 400,000 times a year a device is implanted in their chests to keep a normal rhythm.
With a few flicks of a light switch—on-off-on-off—Stanford University's Oscar Abilez is one step closer to changing the lives of millions.
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.
