[erythroid stem cells derived from myeloid stem cells; the progenitor cells develop in two phases, erythroid burst-forming units (bfu-e) followed by erythroid colony-forming units (cfu-e); bfu-e differentiate into cfu-e on stimulation by erythropoietin, and then further differentiate into erythroblasts when stimulated by other factors.
