Fig. 4. PVCs enhance the hematopoietic differentiation of hPSCs via paracrine action.

Fig. 4

a Experimental scheme used to determine the paracrine effects of PVCs on the hematopoietic differentiation of hPSCs (CHA15 and iPS-NT4-S1). b Representative bright-field images of colonies on day 17 of hematopoietic differentiation. Scale bar, 50 μm. c Effects of PVC-CM on the production of hematopoietic lineage cells for two different exposure times (days 0–9 and days 9–17). d The total number of CFUs was counted by plating 1 × 104 cells in methylcellulose. e Distribution of CFU subtypes. The bars indicate the mean ± SD; *p < 0.05, **p < 0.01 (control vs. CM 0–9 or CM 9–17). CFU-GM, granulocyte-macrophage.
