Concentration-dependent tissue responses in Tg (3EpRE:hsp70:mCherry) zebrafish larvae exposed to acetaminophen (APAP). Fish larvae were exposed to a solvent control (Ai, ii) and three concentrations of APAP (B; C; Di, ii) from 2 to 4?dpf and subsequently imaged via epifluorescence and confocal microscopy. Confocal images illustrate a pronephric convoluted tubule and the liver under control (Aii) and 4.5?mM APAP (Dii) conditions. Arrowheads?=?pronephric convoluted tubule; arrows?=?liver; asterisk?=?retina. For images A?D, fluorescence intensity is represented using a ?Fire? lookup table with a 0?255 pixel intensity calibration bar. Measured APAP culture medium concentrations displayed.
