H2ax/Atm double-deficient mice are embryonic lethal at E12.5. (A) Genotype of embryos obtained from timed breeding between HA+/− parental mice. The other genotypes include H2ax+/−, Atm+/−, H2ax+/−Atm−/−, and H2ax−/−Atm+/− generated because of mitotic cross-over. (B) Morphology of representative E9.5, E10.5, and E11.5 WT and HA−/− embryos. The magnifications for the objective lenses used are marked at the upper right corner of each picture. (C) Morphology of representative E10.5 WT, HA−/−, Atm−/−, and H2ax−/− embryos. Right side view is shown. (Magnification, ×1.25.)
