Numbers represent mean SEM of CFU/106 cells plated. Percentages (in parentheses) represent the numbers with epo treatment relative to the numbers with PBS treatment. P values are for comparisons of the mean CFU between the epo-treated and PBS-treated recipients.
CFC indicates committed myeloid progenitor colonies; CFU, colony-forming units; CFU-GEMM, colony-forming units–granulocyte, erythrocyte, macrophage, megakaryocyte; Epo, erythropoietin; PBS, phosphate-buffered saline.
