We examined HGF and phospho-c-Met expression and localization during the expansion phase and time course of satellite cell activation, which is critical for muscle regeneration after injury. HGF, c-Met, myogenic differentiation 1 (MyoD), and myogenin mRNA levels were significantly increased during muscle regeneration after injury. Phospho-c-Met was localized on the surface of regenerating muscle cells. HGF was colocalized in the same cells as phospho-c-Met, MyoD, or myogenin. The muscle area occupied by HGF-, phospho-c-Met-, MyoD-, or myogenin-positive cells expanded along with expansion of regenerating muscle. Thus, c-Met is expressed in regenerating muscle cells immediately after injury, and its kinase activity is likely activated by HGF expressed by the same cells, suggesting that HGF and c-Met contribute to myogenesis in vivo.}, pages = {85--94}, title = {肝細胞増殖因子の発現は骨格筋再生領域の拡大と同期する}, volume = {39}, year = {2016} }
