Fig. 6From: Significant improvement of direct reprogramming efficacy of fibroblasts into progenitor endothelial cells by ETV2 and hypoxiaCapillary-like network on Matrigel by cells in groups. (a) HFs could not form the capillary-like network. (b) ETV2 transduced HFs in both normoxia and hypoxia, successfully forming the capillary-like network (c) similar to HUVECs (d).
