We now demonstrate that a forced exogenous expression of the four different isoforms of WT1 in K562 does not affect the differentiation response , as judged by accumulation of hemoglobin in response to hemin or the expression of megakaryocytic cell surface markers in response to 12-O-tetradecanoylphorbol-13-acetate ( TPA ).
 protein: megakaryocytic cell surface markers; DNA: WT1; cell line: K562; protein: hemoglobin; protein: hemin
