Figure 4From: Human urine-derived stem cells in combination with polycaprolactone/gelatin nanofibrous membranes enhance wound healing by promoting angiogenesis The wound areas were analyzed on day 0 and day 14 post-surgery in the control, PCL/GT, and USCs-PCL/GT groups. (A) Gross appearances of wounds on day 0 and day 14. (B) Significantly faster wound closure was observed in the USCs-PCL/GT group (*P < 0.05 compared to the PCL/GT group or the Ctrl group).Back to article page
