IGF-1 Colocalizes with Muscle Satellite Cells Following Acute Exercise in Humans
Applied physiology, nutrition and metabolism/Applied physiology, nutrition, and metabolism(2014)
摘要
Insulin-like growth factor-1 (IGF-1) regulates stem cell proliferation and differentiation in vitro. The aim of this study was to quantify the change in satellite cell (SC) specific IGF-1 colocalization following exercise. We observed a significant increase (p < 0.05) in the percentage of SC with IGF-1 colocalization from baseline to 72 h after a bout of resistance exercise. This strongly supports a role for IGF-1 in human SC function following exercise.
