Table 1 Apoptosis during tailbud eversion. Number of cells labeled using the TUNEL assay in 18–19 som (A) and 22–23 som (B) embryos is shown as mean ± SD. (1, 2, 3) Tail regions in which the TUNEL-positive cells were counted (refer to figure 6 for illustration). 0.4 ng of vangl2 MO was injected into each embryo where specified
