Nuclei present in skeletal muscle are about 50% myocyte nuclei and 50% mononuclear cell nuclei. Mononuclear cells found in skeletal muscle tissue samples from mice and humans can be indentified by messenger RNA transcription of cell type markers. Cameron et al. identified nine cell types. The majority (83%) of mononuclear cells in skeletal muscle are located within or adjacent to blood vessels. They include endothelial cells (45% of cells), fibro-adipogenic progenitors (FAPs)(… WebMuscle hypertrophy or muscle building involves a hypertrophy or increase in size of skeletal muscle through a growth in size of its component cells. Two factors contribute to hypertrophy: ... Skeletal muscle cells are however unique in the body in that they can contain multiple nuclei, and the number of nuclei can increase.
