BFU-E colonies derived from PBMCs (A) and CD34+ (B) cells were stimulated with cobalt chloride in semisolid cultures. Cobalt chloride stimulated formation of BFU-E colonies derived from PBMCs (2 × 105/mL) and CD34+ cells (104/mL) in the absence (P < .01) and in the presence of suboptimal concentration of rhEPO (2 U/mL; P < .05) in semisolid cultures. Colony numbers are expressed as mean ± standard deviation.
