FOXO4 immunoreactivity in macaque ovarian tissue from a representative animal during fetal (a, d, and g), prepubertal (b, e, and h), and adult (c, f, and i) life under low (×100; a–c) and high (×400; d–i) magnification. Similar immunoreactivity was observed in all animals within age. Arrows indicate positive FOXO4 staining in the theca layer of an antral follicle. Primary antibody omission negative control (insert in g–i) showed a lack of nonspecific binding. Scale bar = 500 μm (a) and 50 μm (d), and 65 μm (insert).
