Detection of anti-apoptotic BCL2 protein in adolescent human ovary. a Primordial follicle and b) primordial/primary follicle BCL2 positive. BCL2 was heterogeneously distributed in a para-nuclear localization in the oocyte cytoplasm (Arrow heads) (1000X). c Secondary follicles show BCL2 protein in granulosa cells and in the germ-cell proper (200X). d Antral follicle (partial view), BCL2 is detectable in granulosa cells (1000X). e Western blot analysis of human ovarian BCL2 protein (23 kD). f Western blot quantification of BCL2 protein. It was detectable in all samples with variable intensity. O: oocyte; GC: granulosa cells
