Most cardiac muscle cells contain one nucleus, but some have two. The nucleus houses all of the cell’s genetic material. Cardiac muscle cells also contain mitochondria, which many people call ...

Here is a diagram of some ... to an electrical impulse. Cardiac muscle contracts in response to this electrical signal, which is initiated by a special type of cell called a pacemaker cell.

Gap junctions are part of the intercalated discs. When one cardiac muscle cell is stimulated to contract, a gap junction transfers the stimulation to the next cardiac cell. This allows the muscle ...

has been focusing on developing novel stem cell-based treatments for cardiac regeneration. "Heart is an organ composed of cardiac muscles and blood vessels, where vessels are essential to supply ...

The paper's senior author, Dr. Michael Laflamme, said, "These results provide strong evidence that human cardiac muscle cell grafts meet physiological criteria for true heart regeneration.

Stem cells may help regenerate heart muscle damaged after heart attacks. Feb. 14, 2012— -- A promising stem cell therapy approach ... the benefits that cardiac regeneration can offer.

Members of Theme Six are developing stem cell and ... loss of heart muscle after myocardial infarction. One current approach is to investigate gene pathways, many of which are important in heart ...

We therefore hoped to trigger changes in gene activities by reprogramming energy metabolism to turn cell division ability back on in cardiac muscle cells." In further studies, the scientists were able ...
