Stromal cells from the endometrium (EndoSCs), dermis (DermSCs), and adipose tissue (AdipoSCs) undergo adipogenic, osteogenic, and chondrogenic differentiation in vitro. Representative microphotographs of EndoSC, DermSC, and AdipoSC stained for lipid accumulation (Oil Red O) at day 14 of adipogenic differentiation, mineral depositions (Alizarin Red S) at day 21 of osteogenic differentiation, glycosaminoglycans (Alcian blue) at day 21 of chondrogenic differentiation; scale bar 100 μm.
