Abstract
We determined conditions for effective transduction of multipotent mesenchymal stromal cells from human adipose tissue with adenoviral constructs carrying the gene of human bone morphogenetic protein BMP-2. The peak of transgene transcription and BMP-2 protein secretion in the transduced cultures was observed on day 6 after infection. The maximum transcription of BMP-2 gene and genes of osteogenic markers (bone sialoprotein, osteopontin, and osteocalcin) was observed in the medium containing sodium beta-glycerophosphate and ascorbic acid. Addition of D-3 vitamin did not enhance the expression of BMP-2 gene in transduced cells. The obtained cell cultures with high osteogenic potential can be used in bone tissue engineering.
