Figure 4.
A: Transductions were carried out in the presence of 8 μg of Polybrene (Sigma) per ml. After incubation at 37°C for 48 h, transduced MSCs seen by Fluorescence microscopy. High expression of GFP in MSCs shows the high rate of transduction. B: shows transduced MScs by light microscopy after incubation at 37°C for 48 h.
