Adipose tissue histology after fat graft. A Representative images of HE-stained fat grafts four weeks after grafting. Preserved tissue construction and integrity were observed in the 60%, 70% and 80% glycerol groups, while the 60% glycerol group had more obvious vacuole cyst (△) formation. The trehalose group demonstrated apparent fibrosis and inflammatory infiltration (*). Fibrosis, inflammation (*) and vacuole formation (△) were detected in the FBS + DMSO group. The blank group demonstrated a disorganized structure, fibrosis and inflammatory (*) infiltration. (Scale bar: 250 µm.) B The fibrotic areas of grafted fat samples. C The vacuole areas of grafted fat samples. *p < 0.05, **p < 0.01, ***p < 0.001
