Concentration-dependent tissue response in Tg (3EpRE:hsp70:mCherry) - zebrafish larvae exposed to phenylhydrazine (PhZ). Larvae were exposed to a solvent control (Ai-iv) and three concentrations of PhZ (B; C; Di-iv) from 2 to 4?dpf and subsequently imaged via epifluorescence and confocal microscopy. Confocal images of a section of the caudal artery under control (Aii-iv) and 0.05??g/mL PhZ (Dii-iv) conditions. Arrowheads?=?responsive erythrocytes; asterisk?=?non-responsive erythrocytes. For images (A?D), fluorescence intensity is represented using a ?Fire? lookup table with a 0?255 pixel intensity calibration bar. Nominal PhZ culture medium concentrations displayed.
