Tracking rat ESCs in the wound on postinjury day 14. a Rat ESCs expressing EGFP were observed in the wound on days 7, 14, and 21 after the operation. Arrows indicate the EGFP-positive cells. b The rat ESCs have dividing and proliferating phases. c The rat ESCs near blood vessels can express CD31 and participate in the formation of lumen-like structures. Arrows indicate the CD31- and EGFP-positive cells
