Fig 2. In vitro potential of differentiation of Healthy and OA-MSCs.

Fig 2

a) In vitro differentiation and characterization of MSCs. Cultured MSCs from two healthy donors and two OA donors showing similar, plate adherence and fibroblast-like morphology at passage 3. Growth characteristics of MSCs from OA donors were similar as well as the degree of mineralization during osteogenic lineage commitment revealed by Alizarin red S staining (Panel A). (Magnification x 50). b) quantitative measurement of alizarin red staining of osteogenic cultures.
