Surrounding the oocyte as it develops within the ovary follicle are multiple layers of granulosa cells that are bound to the thick specialised extracellular matrix, the zona pellucida. The innermost layer of these cells, the corona radiata, communicate directly with the oocyte by cytoplasmic extensions passing through the zona pellucida. Following release of the oocyte at ovulation, these cells form the granolas layer.
Granulosa cells can also have specific names depending upon location within the ovarian follicle: cumulus oophrous (Latin, cumulus = a little mound; Greek, oo= egg, phorus = carrying) also called cumulus granulosa cells directly around the zone pellucida and released with the oocyte; "corona radiata" forming the initial layer in contact with the zone pellucida; membrana granulosa also called mural granulosa cells forming the layer within the follicle antral wall; discus proligerus can refer to the attachment between cumulus oophrous and membrane granulosa; and mural granulosa cells that line the follicular wall.
In human development, during the first week of development following fertilization the granolsa cell layer and zona pellucida remain surrounding the blastocyst from which it "hatches" to commence implantation.

Follicle Granulosa Cells
|Granulosa cells can also have specific names depending upon location within the follicle.
Cumulus Granulosa Cells
cumulus oophrous (Latin, cumulus = a little mound; Greek, oo = egg, phorus = carrying)
Cumulus granulosa cells lie directly around the oocyte zone pellucida and are released with the oocyte at ovulation. These cells have been shown to exchange biological signals with oocytes through the gap junctions.

Mural Granulosa Cells
Mural Granulosa Cells (MGCs) lining the ovulating follicle remain within the ovary and differentiate to form part of the corpus luteum.
Steroid hormone synthesis by mural granulosa cells is dependent upon the multiligand receptor LOX-1.

Granulosa Cell Markers
In the pig ovary kisspeptin and its receptor are expressed by follicle cells. Kisspeptin, acting through its receptor KISS1R, have a key neuroendocrine role in the regulation of mammalian reproduction. It is not known what specific effect this factor may have on follicle development.
Granulosa cell tumour
An uncommon non-epithelial cancer of the ovary.

- acrosome reaction - The chemical change within the spermatozoa following binding to the zona pellucida, that leads to the release of acrosomal enzymatic contents. These enzymes degrade the zona pellucida and allow a spermatozoa to penetrate an oocyte.

- granulosa cell - A specific cell type that proliferates in association with the oocyte within the developing follicles of the ovary. These cells form the follicle stratum granulosa and are also given specific names based upon their position within the follicle. In the antral follicle, membrana granulosa sits on the follicular basal lamina and lines the antrum as a stratified epithelium. The cumulus oophorus is a column of granulosa cells that attaches the oocyte to the follicle wall. The corona radiata are the granulosa cells that directly surround the oocyte, and are released along with it at ovulation. Following ovulation the corona radiata provide physical protection to the oocyte and granulosa cells within the ovulating follicle contribute to corpus luteum.
- mural granulosa cell - (MGC) granulosa cells that line the follicular wall and have an endocrine function.
