Caption Loss of Speedy A leads to depletion of male and female germ cells. B) Ovaries from PD35 wild-type (WT, Spdya+/+) and Spdyatm1.1Klad/Spdyatm1.1Klad female mice. (C) Testes from PD35 WT and Spdyatm1.1Klad/Spdyatm1.1Klad male mice. (D and E) At PD7, the number of spermatogonia was comparable between WT and mutant testes as indicated by DDX4 staining. (F and G) By PD18, the number of spermatogonia was comparable between WT (F) and mutant testes (G), but some seminiferous tubules showed depletion of spermatocytes in mutant testes (G, arrowhead). (H and I) By PD75, most of the mutant seminiferous tubes were depleted of spermatocytes (arrowhead). (J and K) At 17.5 dpc, the numbers of oocytes were comparable between WT (J) and mutant ovaries (K). (L and M) The number of oocytes was much lower in the mutant ovary (M) compared with the WT ovary at PD1 (L). (N and O) At PD5, the mutant ovaries were depleted of oocytes (O, arrow) compared with the WT ovary (N).
