Figure 1. STAT3 plasmid transfected BMSCs were successfully identified. (A) The expression of CD34, CD45, CD73 and CD90 from BMSCs were detected through the use of flow cytometry. BMSCs proliferation activity at P0 (B), P1-3 (C), P4-6 (D) were determined using the CCK-8 test in the blank control group, negative control group and experimental group prior to transplantation. The STAT3 mRNA expression at P0 (E), P1-3 (F), P4-6 (G). The BMSCs in the experimental group increased more significantly than that in blank control group and negative control group. * P <0.05 versus blank control group + negative control group.
