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 ...

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 ...

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.

"This finding suggests that the new myocytes formed directly in response to need and to the presence of the heart's diseased state, preventing uncontrolled cardiac muscle growth and proliferation in ...

Simply put, HiPSCs are cells derived from mature cells that can be effectively "reprogrammed" into a completely different cell type, such as cardiac muscle cells (cardiomyocytes). By transplanting ...

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.
