<p>A method of inducing the differentiation of embryonic stem cells into ectodermal cells which involves the step of culturing the embryonic stem cells in a non-agglutinated state, and a method of inducing the differentiation of embryonic stem cells into cells originating in ectodermal cells which involves the step of culturing the embryonic stem cells in a non-agglutinated state; a medium and a medium supernatant to be used in these methods; a differentiation inducer to be used in these methods; stroma cells having an activity of inducing the differentiation in these methods or a factor originating therein; an antibody specifically recognizing these stroma cells; an antigen recognizing this antibody; cells induced by the above methods; a method of evaluating a substance relating to the regulation of the differentiation process from embryonic stem cells into ectodermal cells or cells originating in ectodermal cells by performing the above methods, and a screening method; and drugs containing the above-described stroma cells or the factor originating therein, the above-described antibody, the above-described antigen or the above-described cells.</p> |
