DWJM enhances colony-formation capability of CD34⁺cells. (A-C) Formation of BFU-E (A), CFU-GM (B), and CFU–granulocyte, erythroid, macrophage, megakaryocyte (CFU-GEMM) (C) from CD34⁺ cells after 14-day culture. (D-F) Numbers of BFU-E (D), CFU-GM (E), and total colonies (F) per 100 seeded live cells on 4 culture conditions, control, MSCs, DWJM, and DWJM/MSCs. (G-I) numbers of BFU-E, CFU-GM, and total CFU, respectively, derived from 300 live CD34⁺ cells. Six wells were calculated from 3 independent studies (n = 3). Two-tailed Student t tests were used to analyze significance between groups. Data are expressed as mean ± SEM. *P ≤ .05, **P ≤ .01, ***P ≤ .001, ****P ≤ .0001.
