CD34⁺ cells were amplified 7 days later and transferred into the methylcellulose medium for CFU assay. Similar CFU colony numbers were observed among all groups, indicating that the ability of CD34⁺ cells to differentiate was not affected. (A) Comparison of CFU numbers in all groups indicated that there was no significant difference among any of the groups. (B) Comparison of CFU types in all groups. No significant differences were observed among groups. Data are presented as the mean + standard deviation. CD, cluster of differentiation; CFU, colony-forming unit; CFU-GM, colony-forming unit-granulocyte/macrophage; CFU-MIX, colony forming units-mixed; BFU-E, burst-forming unit-erythroid; CFU-E, colony-forming units-erythroid.
