Cytokine (IL16) and tyrphostin actions on ovarian primordial follicle development.
An ovarian follicle is composed of an oocyte and surrounding theca and granulosa cells. Oocytes are stored in an arrested state within primordial follicles until they are signaled to re-initiate development by undergoing primordial-to-primary follicle transition. Previous gene bionetwork analyses of primordial follicle development identified a number of critical cytokine signaling pathways and ...
متن کاملObjects, Actions and Images: a Perspective on Early Number Development1
It is the purpose of this paper to present a review of research evidence that indicates the existence of qualitatively different thinking in elementary number development. In doing so the paper summarises empirical evidence obtained over a period of ten years. This evidence first signalled qualitative differences in numerical processing (Gray, 1991), and was seminal in the development of the no...
متن کاملRegulation of ovarian primordial follicle assembly and development by estrogen and progesterone: endocrine model of follicle assembly.
The assembly of the developmentally arrested primordial follicle and the subsequent transition of the primordial follicle to the primary follicle are critical processes in normal ovarian physiology that remain to be elucidated. Ovarian follicles do not proliferate and the primordial follicles present in the neonate represent the total number of gametes available to a female throughout her repro...
متن کاملParacrine actions of oocytes in the mouse pre-ovulatory follicle.
In mammals, ovulation requires a tight control of extracellular matrix modifications, within both the follicle wall and the inner mass of granulosa cells surrounding the oocyte, namely the cumulus cells. During the pre-ovulatory period, mural granulosa cells promote selective degradation of perifollicular matrix, resulting in the formation of a follicle rupture site. Conversely, cumulus cells s...
متن کاملOvarian Follicle Population and Follicle Size in Anatolian Water Buffaloes
Buffaloes are well known domestic animals in Asia, Mediterranean and Latin American countries of the world for different breeding purposes such as milk, meat, draught and capital [23]. The buffalo has been regarded as poor reproductive efficiency and characterized by low conception rates [6, 22, 23]. Seasonality of buffalo breeding results in a milk supply that exceeds demand in summer and autu...
