Research Abstract	We investigated the role of hepatocyte growth factor in the satellite cell mechanism of activation related to the skeletal muscle hypertrophy in vivo in rat. The results show that whereas the levels of the hepatocyte growth factor receptor and that of the muscle differentiation factor increased in response to muscle load, the levels of hepatocyte growth factor remained unchanged. These results suggest that the qualitative changes rather than quantitative changes of hepatocyte growth factor may be more important for the satellite cell activation.
