There is provided a method of inducing bone marrow stromal cells to differentiate into bone marrow stromal cell-derived Schwann cells in Vitro, comprising the steps of: collecting bone marrow stromal cells from bone marrow and culturing the cells in a standard essential culture medium supplemented with a serum； adding a reducing agent to the culture medium and further culturing the cells； adding a differentiation inducing agent to the culture medium and further culturing the cells； and adding a cyclic AMP-augmenting agent or a cyclic AMP analogue and/or a glial cell differentiation and survival stimulating factor to the culture medium, and further culturing the cells to obtain the bone marrow stromal cell-derived Schwann cells. There are also provided bone marrow stromal cell-derived Schwann cells obtained thereby and a pharmaceutical composition for neural regeneration that comprises them.
