Fig 3. PSA reduced IL-1 β triggered IL-8 in necrotizing enterocolitis intestinal epithelial cells (NEC-IEC).

NEC-IEC cells were pretreated with or without PSA and then exposed to IL-1 β for 24 hrs or treated with PSA alone. The supernatant IL8 levels induced by IL-1 β were reduced by PSA pretreatment. The mean and SEM were from triplicate wells and were representative of three separate experiments with similar results. **P<0.01, ***P<0.001(one-way ANOVA and post-hoc tests).
