Histochemical observation of the cortical zone of oocyte of Indian wall lizard, Hemidactylus flaviviridis (Rüppel).
The cortical zone of oocytes, which lies just below the follicular epithelium appears in the early stages of development, but reaches its fullest growth in vitellogenic oocytes. In the present studies it was found that the cortical zone of Hemidactylus flaviviridis consists of proteins, lipoproteins, carbohydrates, fatty yolk, RNA and little amount of DNA in mature oocytes along with mitochondria and Golgi bodies. In the early oocyte, this zone is fine granular in nature, but during the yolky stages of oocyte, it becomes filled by the vacuolar structure, which shows in it's the presence of fatty and compound yolk. The L1 and L2 types of lipid globules are also observed in the cortical zone during vitellogenic oocyte.
