Ovarian follicle vascularization in fasted pig
Theriogenology, 2004The authors have investigated in the different classes of ovarian follicles the vascular area, the blood vessel distribution, the vascular endothelial growth factor (VEGF) mRNA expression and the VEGF secretion during equine chorionic gonadotropin (eCG) induced follicle growth in prepubertal gilts fed ad libitum or fasted. Immunohistochemistry staining

The Reproductive Lifespan of Ovarian Follicle
Reproductive SciencesThe functional unit within mammalian ovaries is the ovarian follicle. The development of the ovarian follicle is a lengthy process beginning from the time of embryogenesis, passing through multiple different stages of maturation. The purpose of this review is to describe the most basic events in the journey of ovarian follicle development, discussing ...

Impact of endometriosis on the ovarian follicles
Best Practice & Research Clinical Obstetrics & GynaecologyA significant body of evidence has supported a negative impact of endometriosis on ovarian follicles; however, the origin and relevance of this ovarian impairment in endometriosis is still a matter of debate. The ovarian damage can be caused by endometriosis itself or by surgeries aiming to remove endometriotic lesions.

Morphology of the Membrana Granulosa of the Ovarian Follicle
Endocrinology, 1968Each of the cells of the membrana granulosa in mature ovarian follicles of rabbits project from the basement membrane, and are not layered as is generally believed. The arrangement of the cells is that seen in a pseudostratified epithelium. The cells may secrete or excrete materials through their basal end and may be the source of the enzymes ...

Reproduction is one of the key targets in dairy production. Reproductive disorders including cystic ovarian follicles (COF) present a great problem in dairy cow's management. COF in cows and heifers traditionally have been define as an anovulatory fluid-filled hollow structures having diameter ≥ 2.5 cm that persist for 10 or more days in the absence or

Ultrastructure of Human Ovarian Follicles
1980Various criteria have been applied in classifying ovarian follicles (Table 1; Schroder 1930; Block 1951; Watzka 1957; Hertig and Barton 1973; Balboni 1976). The terminology based on both essential morphological and functional changes in the differentiating follicle is used in this chapter (Franchi and Baker 1973).

Origin of ovarian follicle cells in birds
Experientia, 1976In the embryonic Japanese quail ovary, transplanted on chicken chorioallantoic membrane (CAM), follicle cells are derived from somatic cells of the ovarian surface epithelium. No evidence was found for a contribution of other cell groups of the quail ovary in the formation of follicle cells.
