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

Figure 5

Tissue section collected inside the muscle defect after being treated with hydrogel/fat graft complex after 1 month healing under histological stain (Masson Trichrome). (a) Blood vessel can be found in the center of the area (40x). (b) Formation of collagen rich fibrous tissue (40x). (c) The remaining adipose tissue represents only a small volume inside the defect (40x). (d) Degenerated adipose tissue similar to those found in simple fat transplantation can be found (40x).
