Myocyte cell function
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. MEF2 is known to be involved in the development and the looping of the heart (Chen) MEF2 is necessary for myocyte differentiation and gene activation (Black). WebCardiomyocytes (CMs) are striated self-beating and cylindrical rod-shaped muscle cells that fundamentally govern the function of myocardium. The size of a human ventricular CM is 100–150 by 20–35 μm. The cell contains sarcomeric structures as a contractile apparatus ( Severs, 2000 ). The thickness of human.
