Fig. 3From: Wharton’s jelly mesenchymal stem cell-based or umbilical vein endothelial cell-based serum-free coculture with cytokines supports the ex vivo expansion/maintenance of cord blood hematopoietic stem/progenitor cellsThe proliferation of committed progenitors in different coculture conditions. Morphology of CFUs: a CFU-GM, colony-forming unit-granulocyte/macrophage; b CFU-E/BFU-E, colony-forming unit-erythroid/burst-forming unit-erythroid; c CFU-GEMM, colony-forming unit-granulocyte/erythroid/macrophage/megakaryocyte; and d the expansion numbers of CFU-GM, CFU-E/BFU-E, and CFU-GEMM in different coculture conditions, which were significantly higher in adding cytokine groups (UMC, UEC, and UC) than in their counterparts at day 0 (p < 0.05), while there was no significant difference (p > 0.05) in groups without cytokine (UM, UE)Back to article page
