Differentiation toward the adipogenic lineage. (A): Adipogenic differentiation of adipose-derived stromal cells (ASCs) isolated from adipose tissue harvested via laser-assisted liposuction and suction-assisted liposuction was demonstrated by Oil Red O staining, which demonstrated lipid droplet formation. (B): Photometric quantification of Oil Red O staining showed no significant difference between laser-assisted and suction-assisted liposuction-derived ASCs. (C): Gene expression of PPAR-γ, AP2/FABP4, and LPL (*, p < 0.05). (D): Gene expression of heat shock protein HSPA2 (*, p < 0.05). Abbreviations: AP2, adipocyte protein 2; FABP4, fatty acid binding protein 4; HSPA2, heat shock-related 70-kDa protein 2; LPL, lipoprotein lipase; PPAR-γ, peroxisome proliferator-activated receptor γ.
