Expression of c-myc oncogene during differentiation of human burst-forming unit, erythroid (BFU-E).
We investigated the serial expression of c-myc oncogene during differentiation of normal human burst-forming unit, erythroid (BFU-E), in vitro, together with the replating efficiency and the expression of transferrin receptors. We found that the c-myc oncogene was expressed in the early progeny of BFU-E and that this expression decreased during erythroid differentiation. This change of the c-myc expression was well correlated to changes in the replating efficiency and the expression of transferrin receptors. These observations indicate that the c-myc oncogene probably has a physiological role in normal human hematopoiesis as well as leukemic hematopoiesis.
