Figure 3From: Synergistic effect of Indian hedgehog and bone morphogenetic protein-2 gene transfer to increase the osteogenic potential of human mesenchymal stem cellsMonolayer mineralization. Alizarin red S stainings on days 14 and 21 of monolayer cultures transduced with GFP, BMP-2, IHH, and BMP-2 with IHH maintained with osteogenic (left panel) and control (right panel) media. Nonmodified mesenchymal progenitor cells (Ctrl) served as controls. Magnification, Ă—10.Back to article page
