How do satellite cells repair muscle
WebMyonuclear Domains: • Typically, larger muscle fibres are observed to have more myonuclei • Satellite cells fuse to damaged fibres to provide their nuclei and permanently become a part of the fibre-So satellite cells can bind to the damaged area and repair that area/fiber.-So you can have the building and repair of fibers, or you can make fibers/muscle bigger. WebMar 17, 2024 · The muscle is endowed with an exceptional regenerative ability primarily due to a resident population of stem cells called satellite cells (SCs) [1,2,3].Ensconced between the basal lamina and the plasma membrane of muscle fibers, SCs respond to injury or various stress stimuli by becoming activated, and undergoing proliferation, self-renewal, …
