Figure 1From: Synergistic effect of Indian hedgehog and bone morphogenetic protein-2 gene transfer to increase the osteogenic potential of human mesenchymal stem cellsMetabolic activity, proliferation, and levels of transgene products. The figure illustrates the cell metabolic activity (a) and proliferation behavior (b) of native mesenchymal progenitor cells (Ctrl) and after adenoviral transduction with GFP, BMP-2, IHH, and BMP-2 with IHH, as determined with AlamarBlue and Quibit assays. Furthermore, the levels of BMP-2 (c) and IHH transgene products (d), determined with ELISA, are demonstrated. The asterisks indicate statistically significant differences compared with control cultures.Back to article page
