PGCLCs derived from XX, XO and XY ESCs were reaggregated with E12.5 female (XX) gonadal somatic cells. (<b>B</b>) Oocyte differentiation from XX, XO and XY ESCs in culture. Images are rOvaries at the days indicated. Blimp1-mVenus (BV) is a marker of PGC(LC)s and stella-CFP (SC) is a marker of PGC(LC)s and oocytes. BF, bright field. Scale bars, 200 μm. (<b>C</b>) The number of oocytes formed in culture. Each dot indicates the number of oocytes formed in one rOvary. The numbers in the graph indicate the average number of oocytes/rOvary formed in each genotype. XpO and XmO indicate cells having a paternal and maternal X chromosome, respectively. (<b>D</b>) Time-course of the number of PGCLCs/oocytes. The average number of oocytes at the days indicated and SD are shown. The data was compiled from at least three independent experiments. <i>P</i> values were calculated by Steel Dwass test. ***P<0.001, **P<0.01, *P<0.05; NS, not significant.</p>
