Effect of the MSC, BM secretome on the osteogenic differentiation of MSC, WJ. Representative images of Alizarin Red staining performed on MSC, WJ and MSC, BM cultures after three weeks of in vitro osteogenic induction using adherent transwells. Under these conditions, MSC,WJ and MSC,BM display bone induction, whereas MSC,WJ alone are not capable of committing in the osteogenic lineage in a short time-scale. Scale bar: 100 µm
