From: Stereological study of organelle distribution in human mature oocytes

Graphical representation of the variations in organelle relative volume (Vv) observed in (A) the total oocyte, and per oocyte region, (B) cortex, (C) subcortex and (D) inner cytoplasm. Mi: Mitochondria; Di: dictyosomes; Ly: lysosomes; CV: cortical vesicles; VZP: vesicles containing zona pellucida-like material; VZ: vesicles containing granular material; MVB; multivesicular bodies; AL: annulate lamellae; SER: smooth endoplasmic reticulum; VLV: SER very large vesicles; LV: SER large vesicles; MV: SER medium vesicles; SV: SER small vesicles; IT: SER isolated tubules; aSERT: SER tubular aggregates.
