Pancreas length. Tg(ptf1a::GFP) Zebrafish embryos were imaged and measured at 96 hpf following exposure to 50 nM tris(4-chlorophenyl)methanol (TCPMOH), 50 nM tris(4-chlorophenyl)methane (TCPM), or 0.01% dimethyl sulfoxide (DMSO). Asterisks (*) designate statistically significant changes from controls (p < .05). n = 26–32 embryos per exposure group. (a) The mean pancreas length of embryos exposed to 50 nM TCPMOH was reduced by 6%, compared to controls. The mean pancreas length of embryos exposed to 50 nM TCPM was 2.7% larger than the controls. (b) The incidence of hypo- and hypermorphic pancreas lengths was increased to 25% (each) in embryos exposed to TCPMOH.
