HTR-8/SVneo cells were non-treated control (NT), or were exposed to DMSO (0.1% v/v, solvent control) or TBBPA for 4, 8, 16 or 24 h, and then culture medium concentrations of (A) IL-6, (B) IL-8, and (C) TGF-β were quantified by EIA. Bars represent the means ± SE of 4 independent experiments containing 3 replicates each. *P<0.05, significantly different compared to solvent control within same time point. #P<0.05, significantly different from each other. &P<0.05, significantly different compared to 20 μM TBBPA at 4, 8, and16 h. +P<0.05, significantly different compared to 10 μM TBBPA within same time point.
