Fig. S7 Chk1-suppressed apoptosis occurs predominantly during the interphase in zebrafish embryos
(A) Confocal images of the caudal spinal cord in representative embryos of each indicated genotype processed for TUNEL (green)/pH3 (red) double-labeling. While approximately half of the pH3-labeled cells in irradiated p53^e7/e7;chk1^MO embryos are TUNEL positive (see panel B), the bulk of TUNEL-stained nuclei are pH3 negative, implying that death mainly occurs during the interphase. By contrast, cisplatin- or doxorubicin-induced death of MK-2–depleted Tp53^-/- MEFs occurs exclusively in mitosis (Reinhardt et al., 2007).
(B) Percentage of double-labeled cells among >200 pH3-positive cells visualized on images as in panel A. Data are means ± SEM.
