摘要：
A method for obtaining a solution having activity to induce differentiation of an embryonic stem cell into an ectodermal cell or ectoderm-derived cell, which comprises culturing a stromal cell in a culture comprising a polyanionic compound and recovering the culture; a solution having activity to induce differentiation of an embryonic stem cell into an ectodermal cell or ectoderm-derived cell, which is obtainable by the method; and an agent for inducing differentiation of an embryonic stem cell into an ectodermal cell or ectoderm-derived cell.
