The measurement of UC-MSCs secreted cytokines in vitro and in vivo. a, b The anti-inflammatory cytokines IDO and PEG2 secreted by UC-MSCs were measured by ELISA after being treated with 200 ng/ml IFN-γ. c, d The IL-6 and IL-1β were measured by ELISA in a TNBS-induced colitis mouse model. e, f The IDO and PEG2 were measured by ELISA in aTNBS-induced colitis mouse model. **p < 0.01, * p < 0.05, Student’s t-test. For all experiments, n = 3 healthy donors/group, and data shown are mean ± SD.
