The effect of overexpression of NTFs on the osteogenic differentiation of MSCs. Transduced MSCs were cultured in osteogenic induction medium for 21 days. (a) Cells were stained with anti-human osteocalcin antibody and pictured in representative areas. Scale bar = 100 μm. (b) Relative osteocalcin levels. versus control ().
