Coloured transmission electron micrograph (TEM) showing the zona pellucida (pink) located between the oocyte (blue) and the follicular cells (brown) of the corona radiata. Short microvilli of the oocyte and longer and thicker microvilli of the follicular cells (some reaching the oocyte surface) are crossing the zona pellucida. Mitochondria (red), endoplasmic reticulum (green) and dark cortical granules can be seen in the oocyte cytoplasm. | |
