Abstract
Erythroid progenitor [mouse] cells in +/+ and Sl/Sld fetal livers manifested as erythroid burst-forming units (BFU-E) and erythroid colony-forming units (CFU-E) were assayed in vitro during early development. The proportion of BFU-E was higher in mutant than in normal fetal livers. The proportion of CFU-E was less in the mutant than in the normal. The defect in Sl/Sld fetal hepatic erythropoiesis is apparently expressed at the steps of differentiation that effect the transition from BFU-E to CFU-E.
