Age changes in skeletal muscle cells, proliferation, and glycogen

الملخص

Skeletal muscles are one of tissues that affected by aging, as they become atrophied, weaker, and more prone to damage after exercise. Skeletal muscle resident cells and nuclei are either related to the muscle fibers as satellite cells, and myonuclei, or outside the muscle fibers as fibroblast, pericytes, endothelial cells, and mast cells,. Their population and the proliferative profile changed with aging. On the hand skeletal muscle fibers contain about 2% of its weight is glycogen, this glycogen used to keep the muscle functioning if it fails to receive sufficient oxygen. Glycogen had been studied in skeletal muscles under various states of muscle activities and nutritional states but glycogen quantification with aging is not clearly defined .
