Myocyte facts
A muscle cell is also known as a myocyte when referring to either a cardiac muscle cell (cardiomyocyte), or a smooth muscle cell as these are both small cells. A skeletal muscle cell is long and threadlike with many nuclei and is called a muscle fiber. Muscle cells (including myocytes and muscle fibers) develop from embryonic precursor cells called myoblasts. Web(3) The functional cells of the uterus are the myocytes, which are a homogeneous cell type responsible for the generation of contraction forces, passage of action potentials, and control of contractility. (4) The phasic contractions of the uterus are typical for visceral smooth muscle.

WebMyocytes are also called contractile cells because they contract to allow the heart to pump blood. Myocytes are different from skeletal muscle cells, which get their action potential signals directly from neurons. Okay, now let’s take a closer look at the chemistry that gets that action potential moving. WebAug 15, 2004 · In cultured cardiomyocytes, adenoviral-mediated gene transfer of activated calcineurin reduced oxidative stress induced cell death, whereas calcineurin antagonism increased TUNEL positivity of myocyte nuclei [76]. These findings indicates that calcineurin signaling imparts a degree of protection against cell death in the heart.
WebMEF2, Myocyte Enhancer Factor 2, is a transcription factor with four specific numbers such as MEF2A, B, C, and D. Each MEF2 gene is located on a specific chromosome.
