Figure 3.

The maximum diameter of VX2 bladder tumor 4 weeks after tumor inoculation. Control 2 was used to test whether or not liposome could affect the result. Compared with control 1, p>0.05 indicated liposome did not affect the result. The comparison between group control 3 and group control 1 indicated that MSCs were conducive to VX2 tumor growth. The expression of TGFβ1 receptor and Smad2 of MSCs were blocked in group test 1 and group test 2, respectively. Compared with group control 1, the mean maximum tumor diameter was significantly decreased in group test 1 and group test 2
