The change of a skeletal muscle satellite cell from a mitotically quiescent to a mitotically active state following exposure to some activating factor such as a cellular or soluble ligand. In adult muscle, satellite cells become activated to divide and differentiate in response to muscle damage.

The process in which a relatively unspecialized cell acquires specialized features of a satellite cell.

The multiplication or reproduction of satellite cells, resulting in the expansion of the cell population. Satellite cells are quiescent cells that are located between the basal lamina and the plasmalemma of the muscle fiber, which are the main contributors to postnatal muscle growth. In adult muscle, satellite cells become activated to divide and differentiate in response to muscle damage.

The orderly movement of a myoblast from one site to another, often during the development of a multicellular organism. A myoblast is a cell type that, by fusion with other myoblasts, gives rise to the myotubes that eventually develop into skeletal muscle fibers.

Formation of myofibrils, the repeating units of striated muscle.

The expansion of a muscle cell population by cell division.

The attachment of a cell to a second cell of the identical type via adhesion molecules.

The attachment of a cell to a second cell of the identical type via adhesion molecules.

The process in which myelin sheaths are formed and maintained around neurons. Oligodendrocytes in the brain and spinal cord and Schwann cells in the peripheral nervous system wrap axons with compact layers of their plasma membrane. Adjacent myelin segments are separated by a non-myelinated stretch of axon called a node of Ranvier.

The removal of the apoptotic cell by phagocytosis, by a neighboring cell or by a phagocyte.

The removal of the apoptotic cell by phagocytosis, by a neighboring cell or by a phagocyte.

The process in which a cell interprets signals (in the form of specific proteins and lipids) on the surface of a dying cell which it will engulf and remove by phagocytosis.

The process whose specific outcome is the progression of a muscle cell over time, from its formation to the mature structure. Muscle cell development does not include the steps involved in committing an unspecified cell to the muscle cell fate.

An invagination of the cell membrane formed by an actin dependent process during phagocytosis. Following internalization it is converted into a phagosome.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
