Fluoromicrographs (a1, a2) and brightfield images (b1, b2) of LV-Ctrl (a1, b1)- or LV-Tbx20 (a2, b2)-transduced Ad-MSCs that were maintained in osteogenic differentiation medium for 21 days. c Expression of Tbx20 (murine) in transduced cells, 14 days after transduction. RT-qPCR demonstrated that the Tbx20 expression in LV-Tbx20 transduced cells was around 20 times higher than its expression in LV-Ctrl transduced cells.***Indicates significant differences (p < 0.001) between LV-Ctrl and LV-Tbx20
