Figure 4 The LV-BMP9 infection enhanced cell viability and upregulated mRNA transcriptions of osteogenic factors (BMP9, RUNX2, OCN, OPN, OSX) in BMSCs. (A) Determination of LV or LV-BMP9 infection efficacy in BMSCs by immunofluorescence assay. (B) LV-BMP9 infection increased cell viability of BMSCs. (C) Expression of osteogenic factors, including BMP9, RUNX2, OCN, OPN, and OSX, was increased in LV-BMP9-infected BMSCs. # p<0.05 and ## p<0.01 versus the values of LV group. BMSCs – bone mesenchymal stem cells; RUNX2 – runt-related transcription factor 2; OCN – osteocalcin; OPN – osteopontin; OSX – osterix; BMP9 – bone morphogenetic protein.
