This will partially remove other small cells such as fibroblasts and endothelial cells. Note: Repeat digestion with trypsin 1–2 times to get more myocytes if necessary. Cardiomyocyte Purification Timing: 20 min

網頁Cardiac action potentials differ from the APs found in other areas of the body. Typical neural AP duration is around 1ms and those of skeletal muscle are roughly 2-5ms, whereas cardiac action potentials range from 200-400ms. Nervous and muscle cells (as well as non-pacemaker cardiac cells) use the opening of Na channels to facilitate the ... 網頁Abstract. While the majority of the cardiac myocyte death that makes up the final infarct occurs during ischemia and the first few minutes of reperfusion, cell death does not stop there. In fact necrosis and apoptosis, and potentially autophagy, can continue in the previously ischemic area for up to 3 days post-reperfusion.
