According to the medium composition for culturing the muscle stem cell comprising Curcumin Longa, glysin, or insulin according to an aspect, the proliferation ability and differentiation potency of the muscle stem cell do not degrade even when the muscle stem cell is cultured in vitro, and thus there is an effect of culturing the stem cell in large quantities. In this regard, since an expensive culture medium containing bFGF can be effectively replaced, it is economical, and when the muscle stem cell is cultured, appropriate differentiation time can be selected, and thus, the muscle stem cell can be differentiated as needed, resulting in the increase in the quality of in vitro meat.
