XY Body Forms Normally during Pachynema in Dmrt7 Mutant Mice
(A) Testicular cells spread and stained with antibodies to γH2AX (red) and SYCP3 (green). In pachytene cells, γH2AX is concentrated in the XY body both in wild-type and Dmrt7 mutant.
(B) Testes from 6-wk-old mice sectioned and stained with antibody to γH2AX (red).
(C) Testes from 6-wk-old mice sectioned and stained with antibody to SUMO-1 (green). Abundant pachytene cells with XY bodies are present in wild-type and mutant testes.
