Aging-related increase in adipogenic capacity of ADSCs and attenuation by pre-exposing to mechanical strain. A. Oil-Red O staining of adipogenic colonies (14 days) formed by young, adult, and old ADSCs with or without pre-strain. Scale bars = 500 μm. B. AP2 and PPARγ expression in ADSCs that were with or without pre-strain and were adipogenically induced for 14 days *: P < 0.05, compared to non-strained old ADSCs. N = 3.
