The effects of hUC-MSC transplantation on the production of proinflammatory cytokines in ACLF rats. ACLF 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), and IL-1β (d) were detected by ELISA at hours 4, 12, and 24 (4h, n = 3/group; 12h and 24h, n = 4/group). Data are presented as the mean ± SD. *P < 0.05, **P < 0.01
