Aspect of primordial follicles in culture. A: Aspect of a primary follicle after 6 days in culture. Observe the growth of cells of ovarian stroma (os). B: Aspect of two follicles considered degenerated in culture. Observe the absence of growth of cells of ovarian stroma and the darkened stain of oocytes (o) (original magnification ×200).
