UAL- and SAL-derived hASC-seeded hydrogel groups improve cutaneous wound vascular density. CD31 staining with 4′,6-diamidino-2-phenylindole (DAPI) confirmed a significant increase in neovascularization among the hASC-seeded hydrogel groups. Scale bar = 100 μm. n = 8. ∗, p ≤ .05. All data are given as mean ± 1 SEM. Abbreviations: CTRL, control; HPF, high-power field; SAL, suction-assisted liposuction; UAL, ultrasound-assisted liposuction.
