Research Abstract

I investigated the roles of quiescent satellite cell-specific genes in vitro and in vivo. One of specific genes, calcitonin receptor suppressed proliferation and migration of satellite cells in vitro. In addition, hesr1 and 3 double knock mice exhibited the decreased number of muscle satellite cells in vivo. Furthermore self-renewal potential of muscle satellite cells were different among mouse strain, and the potential were directly related to muscle weight.
