Paclitaxel treatment does not increase apoptosis in larval fish. (A and B) Image assemblies of TUNEL staining in vehicle (A) and paclitaxel (B)-treated larvae following 3 h (Top panels) and 96 h (Bottom panels) of incubation in either DMSO/Ringers solution or paclitaxel. DMSO-treated controls have slightly increased apoptosis compared with paclitaxel-treated larvae. (C) Positive control pretreated with micrococcal nuclease shows ubiquitous staining. (D) Negative control without labeling reagent. (E) Quantification of average apoptotic cell number in 50 µm3 within caudal fins shows a slight (but not significant) increase in apoptosis in DMSO/vehicle controls (six fish per group). (Scale bar, 200 µm.)
