  Fig. 2. Distribution of Dmrt1 in ZZ and ZW gonads during tadpole development. Immunostaining with anti-Dmrt1 and anti- VASA antibodies was performed on gonadal sections from ZW and ZZ tadpoles at stages 56 (A) and 62 (B). Nuclei were stained with TO-PRO-3. Oc, oocyte; Og, secondary oogonium; POg, primary oogonium; PSg, primary spermatogonium; pSe, pre-Sertoli cell. White arrowheads and arrows indicate Dmrt1-expressing pre- Sertoli cells and primary oogonia, respectively. Typical GSCs with somatic cells and their 2.59 magnification images are shown in the dashed squares. A dashed polygon indicates a typical cyst consisting of secondary oogonia.

  Fig. 4. BrdU incorporation and Dmrt1 expression in the ZW developing ovary and ZZ adult testis. Immunostaining with anti-Dmrt1 and anti-BrdU antibodies was performed on the immature tadpole ovary at stage 62 and the mature testis of an adult frog. Nuclei were stained with TOPRO- 3. Og, secondary oogonium; POg, primary oogonium; PSg, primary spermatogonium; Sg, secondary spermatogonium; Sc, spermatocyte.

  Fig. 5. Distribution of cH2AX in ZZ and ZW gonads during development. Immunostaining with anti-Dmrt1 and anticH2AX antibodies was performed on gonadal sections from ZW and ZZ tadpoles at stages 53 and 62 (A) and on gonadal sections from a ZZ adult frog (B). Nuclei were stained with TO-PRO. Oc, oocyte; POg, primary oogonium; PSg, primary spermatogonium; Sg, secondary spermatogonium; Sc, spermatocyte. White arrowheads and arrows indicate Dmrt1- or cH2AX-positive primary GSCs and leptotene/zygotene oocytes, respectively.
