Photomicrograph of SOD2 immunostaining in the sheep ovary during the follicular phase. A & B Showing slight SOD2 immunostaining in the stroma cells (St) and negative SOD2 immunostaining in the primordial (PF) and primary (PrF) follicles. C-E Showing moderate SOD2 immunostaining in the granulosa cells (G) of the growing (C & D) and antral (E) follicles and negative SOD2 immunostaining in the oocyte. F Showing moderate SOD2 immunostaining in theca externa cells (TE) and negative SOD2 immunostaining in the granulosa cells (G) and theca interna cells (TI) of preovulatory follicles. Original magnification; A-B & D-F: X400, scale bar = 50 µm, C: X200, scale bar = 100 µm
