Differentiation capacity of MSCs. Image (a) Morphology of MSC from Different sources. Cells were incubated for 3 weeks with adipogenic, osteogenic, and chondrogenic media. Representative images (b) of differentiated cells first row represent day 0 of coloration. Second row shows that the intracellular lipid droplets were confirmed by Oil Red O staining compared to the control cells. The third row, the presence of calcium deposit was visualized by Alizarin Red staining compared to the control. The presence of GAG in the last row was confirmed with Alcian Blue staining and the solid chondrogenic micromass compared to the control
