The BMP2 and HIF1α protein expressions in the five BMSC groups. a BMSCs that were infected with Adv-BMP2-hrGFPand Adv-HIF1αmu-hrGFP. b BMSCs that were infected with Adv-BMP2-hrGFP. c BMSCs that were infected with Adv-HIF1αmu-hrGFP. d BMSCs that were infected with Adv-hrGFP. e Blank control BMSCs (no infection). BMSCs: mesenchymal stem cells. BMP2: bone morphogenetic protein 2. hrGFP: human renilla reniformis green fluorescent protein. HIF1αmu: hypoxia-inducible factor 1 mutation
