Fig. 4. Abnormal morphology of the heart of the pro-caspase-3 transgenic zebrafish. (A) wild-type embryo. (B,C) casp-1 and casp-2, transgenic embryos expressing pro-caspase-3. Arrows indicate the ventricles of embryos at 48 h.p.f. The heart cavity of the transgenic embryos was enlarged (casp-1 line). The ventricle formed an elongated structure and was reduced in size.
