we conclude that the cell which responds to thymopoietin in the komuro-boyse assay by expressing the t cell surface phenotype is the same cell ( pro-thymocyte ) that normally migrates in vivo from hemopoietic tissues to the thymus and is there induced by thymopoietin to express the phenotype of an early t cell .
