hASCs had fibroblast-like morphology as observed under a phase-contrast microscope, at passage 0 (a) and 3 (b). Adipogenic differentiation was confirmed with positive Oil Red O staining (c). Osteogenic differentiation was confirmed with positive ALP (d) and Alizarin Red staining (e). Chondrogenic differentiation was verified with immunofluorescent staining for collagen type II (f). ALP activity of hASCs at indicated days after incubation with osteogenic differentiation medium (g)
