    16.7   Primary follicle Version française
Primary multilaminar follicle (Pa-m) in the ovarian cortex.

The enlarged oocyte in the centre of the follicle shows the nucleus (N) in an abundant and granulated cytoplasm. This nucleus (N) contains diffuse chromosomes and a large nucleolus (*).

This oocyte is surrounded by several layers of follicular cells (Fo). Next to the oocyte, a layer of follicular cells (arrowhead) is closely applied to a thick eosinophilic layer. This layer, rich in glycoproteins, corresponds to the zona pellucida (ZP), which is deposited on the plasma membrane of the oocyte.

Numerous fibrocytes (Fi) of the stroma surround this growing follicle.
