Ovarian stimulation and granulosa-cell tumour
Lancet, The, 1993Ovarian stimulation in the treatment of infertility is far from physiological because patients and their ovaries are exposed to high concentrations of gonadotropins. Many studies have focused on the two most common side-effects of ovarian stimulation--ie, hyperstimulation and multiple pregnancy. We describe 12 patients in whom granulosa-cell tumour was

ULTRASTRUCTURE OF A GRANULOSA CELL TUMOUR
Obstetrical & Gynecological Survey, 1970Abstract. The fine structure of a hormonal active granulosa cell tumour is described. The greater part of the tumour consisted of a cell type resembling the granulosa cell of the normal follicle. It contained many Golgi elements but was poor in smooth and rough endoplasmic reticulum.

Bioencapsulation of Oocytes and Granulosa Cells
2023A protocol for the encapsulation in sodium alginate of granulosa cells in primary culture and coculture of oocyte-cumulus complexes is reported. Sodium alginate forms strong gels when jellified with barium ions, allowing the self-organization of cells into a 3D structure.

Pediatric Pathology, 1990
A 2-year-old girl presented with isosexual precocity, and a juvenile granulosa cell tumor of the left ovary was removed. The tumor was unusual in that striated muscle differentiation of the tumor cells was demonstrated. This suggests that the mesenchymal cells retain the potential for divergent differentiation.

Molecular and Cellular Endocrinology, 2004
The ovary is a complex endocrine gland responsible for production of sex steroids and is the source of fertilizable ova for reproduction. It also produces various growth factors, transcription factors and cytokines that assist in the complex signaling pathways of folliculogenesis. The ovary possesses two primary steroidogenic cell types.

Granulosa cell-oocyte interactions
European Journal of Obstetrics & Gynecology and Reproductive Biology, 2004Throughout oogenesis the oocyte and follicle cells establish an intricate system of mutual interactions that ultimately lead to the acquisition of their respective competences. Paracrine factors released by both cell types are believed to stimulate formation of the primordial follicle and support the initial phases of follicle growth. At the same time,

We present three-dimensional computed tomographic findings of a juvenile granulosa cell tumor of the ovary at FIGO stage IA in a 17-year-old woman. Juvenile granulosa cell tumor is one of the rare sex cord stromal tumors of the ovary. Most tumors at FIGO stage IA have a favorable prognosis, whereas those at higher stages have a less favorable outcome.

SUMMARY Unilateral ovariectomy was performed on 3 mares affected with granulosa cell tumors. Tumor fluid in each mare was found to contain estrogen, testosterone, and progesterone. In 2 mares, preoperative blood plasma concentrations of these hormones were comparable to those of a series of clinically normal mares.

Culture of granulosa cells has for long provided a useful tool to understand the molecular processes underlying ovarian follicle development. Among all species investigated, cattle have become an excellent model for in vitro studies on follicular biology, both because of their resemblance with humans in terms of follicular biology and the importance of
