Basic mechanisms of ovarian function: germ cells
Recent work is reviewed on several molecular aspects of gene expression during oocyte maturation and early development. Several analyses have been carried out on protein synthesis patterns using the high resolution two-dimensional polyacrylamide gel electrophoresis technique. The protein pattern of some 400-500 spots in sea urchin oocytes before and just after fertilization are quite similar. B...

15 صفحه اولDynamics and role of MicroRNAs during mammalian follicular development
Ovarian functions, which involve dynamically regulated processes of selection, recruitment and dominance, are known to be regulated by an array of genes, which are expressed in spatiotemporal manner in follicular somatic cells and gametes. This differential expression of genes in mammalian follicular cells is partly regulated by posttranscriptional gene regulators named microRNAs (miRNAs). In a...
متن کاملCrowding and Follicular Fate: Spatial Determinants of Follicular Reserve and Activation of Follicular Growth in the Mammalian Ovary
Initiation of growth of resting ovarian follicles is a key phenomenon for providing an adequate number of mature oocytes in each ovulation, while preventing premature exhaustion of primordial follicle reserve during the reproductive lifespan. Resting follicle dynamics strongly suggest that primordial follicles are under constant inhibitory influences, by mechanisms and factors whose nature rema...
متن کاملRegulation of Follicular Growth and Development in Sheep
This manuscript reviews the present knowledge related to folliculogenesis in sheep.Folliculogenesis starts with formation of primordial follicles before birth, present as a pool containing a certain number of follicles. By the attainment of puberty, a group of follicles from that pool starts to grow, a process known as primordial follicle activation or recruitment. The number of growing primord...
