The effects of hUC-MSC transplantation on the production of proinflammatory cytokines and antiinflammatory cytokines in rats with ACLI. ACLI rats were transplanted with hUC-MSCs or 0.9% sodium chloride as a control. The serum levels of the cytokines TNF-α (a), IFN-γ (b), IL-6 (c), IL-1β (d), TGF-β1 (e), IL-4 (f), and IL-10 (g) were detected by ELISA at weeks 1, 2, 4, and 6 (n = 3/group). Data are presented as the mean ± SD. *P < 0.05
