Statistical analysis of the level of cytokines in the RPE-Bruch’s membrane choriocapillaris complexes. a ELISA showed that the level of IL-6 significantly decreased at 14 d and 28 d, (b) and that of IL-10 significantly increased until 28 days after UCMSC and S-UCMSC intravenous transplantation. c The levels of BDNF were significantly increased at 14 d after transplantation and those of bFGF were increased at 7 d and 14 d (e). d and f The levels of CNTF and HGF were significantly continuously upregulated until 28 days after intravenous infusion (n = 3). *P < 0.05; **P < 0.01; ***P < 0.005; ****P < 0.001 versus UCMSCs; ^#P < 0.05; ^##P < 0.01, ^###P < 0.005; ^####P < 0.001 versus S-UCMSCs
