Fig. 4From: 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 long-term reconstruction capacity maintenance. a The percentage of CD34+ cells under different coculture conditions, and no significant difference was observed (p > 0.05). b The percentage of CD34+CD38− cells under different coculture conditions. The asterisk indicates p < 0.05, comparing the cells under the UEC and UC conditions with those under the UMC condition. The number sign indicates p < 0.05, comparing the cells under the UE with those under the UM conditions. c The numbers of LTC-ICs in different coculture conditions. The asterisk indicates p < 0.05, comparing the numbers of LTC-ICs at day 10 with those at day 0, that showed the results of the increase in UEC and decrease in UM and UE conditionsBack to article page
