Figure 5
Histological evaluation and immunofluorescence staining of fat grafts after 3 months of transplantation. (a) H&E-stained pictures (low magnification and high magnification) and (b) immunofluorescence stained images (perilipin: green fluorescence) of grafts slices taken from three groups at month 3. Black arrows represent fibrosis and black hexagrams indicate vacuoles. White hexagrams show perilipin-negative crown-like structures. Quantitative analysis of (c) diameter of adipocytes, (d) area of fibrosis tissue, and (e) number of per perilipin-positive cells. .
