In vitro effects of SVF prehypoxic administration on renal tubular epithelial cell (TEC) in hypoxic environment. (A): Prehypoxic administration of SVF could significantly promote the proliferation of hypoxic renal TEC, compared with the control and posthypoxic administration groups. (B): Prehypoxic administration of SVF could significantly promote the scratch wound healing of hypoxic TEC, compared with the control and posthypoxic administration groups. (C): Representative images of cell scratch wound healing (magnification, ×100). (D): Prehypoxic administration of SVF could significantly reduce the apoptosis of hypoxic TEC, compared with the control and posthypoxic administration groups. (E): Representative flow cytometry histograms of Annexin V/PI apoptosis assay in different groups. ∗, p < .05 (vs. control and SVF post-H); #, p < .05 (vs. control). Abbreviations: FITC, fluorescein isothiocyanate; PI, propidium iodide; SVF, stromal vascular fraction; SVF Post-H, posthypoxic administration of stromal vascular fraction; SVF Pre-H, prehypoxic administration of stromal vascular fraction.
