a DAPI staining and immunostaining for SYCP1 (red), SYCP3 (green), and VASA (cyan) in Stra8+/+ and Stra8−/− SSC cultures with indicated treatment. Scale bars, 10 µm. b Representative chromosome spreads stained by SYCP1 (red) and SYCP3 (green) from Stra8+/+ and Stra8−/− SSC cultures. Percentages of germ cells at the indicated meiotic stages are shown below (n = 50 cells). c DAPI staining and immunostaining for SYCP1 (red), SYCP3 (green), and VASA (cyan) in Spo11+/+ and Spo11−/− SSC cultures with indicated treatment. Scale bars, 10 µm. d Representative chromosome spreads stained by SYCP1 (red) and SYCP3 (green) from Spo11+/+ and Spo11−/− SSC cultures. Percentages of germ cells at the indicated meiotic stages are shown below (n = 50 cells).
