obsolete initiation of skeletal muscle satellite cell activation by growth factor signaling, involved in skeletal muscle regeneration https://github.com/geneontology/go-ontology/issues/25737 true The reason for obsoletion is that the term is pre-composed and should be represented as a GO-CAM model. GO:0014815 biological_process OBSOLETE. Signaling between growth factors and their receptors that results in the activation of satellite cell, where this process is involved in skeletal muscle regeneration. 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.
