Expression of inflammatory factors. (a) ELISA of inflammatory factor expression by groups at indicated time points. The hAMSCs-IL-10 group showed the lowest expression of proinflammatory factors IL-6 and TNF-α and the highest expression of anti-inflammatory cytokine IL-10 on days 3, 7, and 14 compared with the hAMSCs, hAMSCs-Null, and control groups. Expression of proinflammatory factors IL-6 and TNF-α decreased after treatment with hAMSCs or hAMSCs-Null compared with the control on days 3, 7, and 14. Expression of anti-inflammatory cytokine IL-10 increased after treatment with hAMSCs or hAMSCs-Null compared with the control on days 3, 7, and 14. No significant differences among the hAMSCs and hAMSCs-Null groups were seen in expression of inflammatory factors (). (b) qPCR of inflammatory factor expression, in accord with ELISA results (). and &.
