Application of Hydrogel in Reconstruction Surgery: Hydrogel/Fat Graft Complex Filler for Volume Reconstruction in Critical Sized Muscle Defects

Figure 9

Tissue healing process in muscle introduced with (a) simple fat graft and (b) hydrogel/fat graft complex in 6-month time point. (4x) Most of the adipose tissue has degenerated into fibrous tissue in simple fat graft transplantation, while subjects treated with hydrogel/fat graft complex show traces of adipose tissue developing in between fibrous tissue. It is noticeable that there is a more even distribution of adipose tissue inside the collagen based fibrous tissue for subjects introduced with hydrogel/fat graft complex.
