Analysis of somatic cell apoptosis in (A,E,I,M) control siblings, (B,F,J,N) ctdsp2^−/− mutants, (C,G,K,O) ctdsp2^−/− embryos injected with ctdsp2 mRNA, and (D,H,L,P) tp53-knockout ctdsp2^−/− embryos at 24 h post-fertilization (hpf). TUNEL staining signals, indicative of apoptotic cells, were observed in the head, pharyngeal arch, and trunk in ctdsp2^−/− mutants at 24 hpf. The signals were reduced after ctdsp2 mRNA injection. Control siblings and ctdsp2^−/− embryos with tp53 knockout showed no apparent apoptotic signals. The dotted boxes highlight areas of TUNEL staining, emphasizing specific areas where apoptosis was detected.
