DescriptionMultinuclear muscle fiber cells and some associated mononuclear cells.jpg
English: Skeletal muscle cell types include: very large multinuclear muscle fiber cells; small endothelial cells that line the inside of capillary blood vessels; small fibro-adipogenic progenitor cells (FAPs) which are muscle-fiber-adjacent multipotent mesenchymal stem cells that under different conditions can differentiate into adipocytes, fibroblasts or osteocytes. Also shown are pericytes situated on the outer surface of blood capillaries, where they interact with the underlying endothelial cells. In addition, satellite cells are shown that can fuse with muscle fibers and contribute new myonuclei to muscle fibers, grow into new myocytes, or support focal membrane damage repair.[1]
