Overview images after rat was anatomized. PEU (b) and PEU-SF (c) were implanted in Wistar rat subcutaneously for 40 d. (a) is the appearance of live rat after scaffolds were implanted for 3 d. The lower inserted image showed the operated wound recovered and the fur regenerated completely after scaffolds were transplanted for 20 d. The upper inserted images in (b) and (c) showed the scaffold overview to display the vascularization.
