SKELETAL MUSCLE PRECURSOR CELLS AND METHOD FOR PURIFYING SAME, COMPOSITION FOR TREATING MYOGENIC DISEASES, AND METHOD FOR PRODUCING CELL GROUP CONTAINING SKELETAL MUSCLE PRECURSOR CELLS

摘要

The present invention provides a composition that is for treating myogenic diseases and that contains a cell group including skeletal muscle precursor cells differentiation-induced from pluripotent stem cells, the composition being characterized in that the cell group includes the skeletal muscle precursor cells that are Pax7-positive, and are CD146 (MCAM)-positive and CD57-negative on the surface thereof. The present invention also provides a method for purifying skeletal muscle precursor cells.
