Effect evaluation of interleukin-1 receptor antagonist nanoparticles for mesenchymal stem cell transplantation

Figure 4 Changes in liver cell proliferation in all four groups. A, B and C showed the anti-Ki67 stain of Group A at the time point of D3, W1 and W4, respectively (×200); D, E, F and G, H, I showed anti-Ki67 stain of Group B and Group C, respectively, just as Group A did (×200); J: Changes in the number of Ki67+ cells demonstrated that Group D had better long-term proliferation. ^aP < 0.05 vs control group. IL-1Ra: Interleukin-1 receptor antagonist; MSCs: Mesenchymal stem cells; D-gal: D-galactosamine.
