TGF-β1 decreased serum IL-6 and IFN-γ levels in experimental NEC. Blood was collected from vehicle- or TGF-β1-treated experimental pups with the same degree of intestinal injury and from healthy dam-fed controls. Serum was prepared and subjected to a multiplex cytokine assay. Data (n ≥ 5) are presented as means ± S.E. * and ** depict p < 0.05 and 0.01, respectively, as compared with the vehicle-treated group by one-way analysis of variance with Bonferroni's correction.
