Morphological analysis and apoptosis rates of adipose tissue after cryopreservation. (A) Gross morphology of fresh adipose tissue two weeks after being subjected to different cryopreservation protocols. (B) Electron microscopy scan of fresh adipose tissue and adipose tissue after cryopreservation of different cryopreservation solutions for two weeks, scale bar (top): 1 mm, scale bar (bottom): 500 μm. (C) Flow cytometry analysis of the apoptosis rates of SVF cells from adipose tissue cryopreserved with different solutions. (D) Quantitative analysis of the apoptosis rate of SVF cells; *, indicates a comparison with the PBS group, P < 0.05; #, indicates a comparison between groups, P < 0.05
