1. (A) Diagram illustrating axes of mitoses at different stages of follicle development and in different layers of the GCs. Thicker lines mark predominant angle.
(A) Diagram illustrating axes of mitoses at different stages of follicle development and in different layers of the GCs. Thicker lines mark predominant angle. (B-G) H&E stained sections of day 12 (B, C, E–F) and 21 (D) ovary showing angle of mitoses (arrows). (B) Mitosis parallel to basal lamina and oocyte surface in transitional follicle. (C) Mitosis perpendicular to basal lamina and oocyte surface in primary follicle. (D and E) Perpendicular mitosis in GC spanning between GC and oocyte. (F) Perpendicular mitosis in a basal GC. (G) Mitosis in an inner GC parallel to oocyte surface. Scale bars: 20 μm.
