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...

Basic mechanisms of ovarian endocrine function

This review outlines the current understanding of ovarian endocrine development and regulation with both physiological and biochemical background to provide a framework applicable to problems concerning environmental agents and ovarian endocrine function. Two approaches are used. First, the endocrine regulation of follicle development and corpus luteum function is considered in the classical se...

Basic fibroblast growth factor suppresses meiosis and promotes mitosis of ovarian germ cells in embryonic chickens.

Basic fibroblast growth factor (bFGF or FGF2) plays diverse roles in regulating cell proliferation, migration and differentiation during embryo development. In this study, the effect of bFGF on ovarian germ cell development was investigated in the embryonic chicken by in vitro and in vivo experiments. Results showed that a remarkable decrease in bFGF expression in the ovarian cortex was manifes...

Sexual plasticity of ovarian germ cells in rainbow trout.

The sexual plasticity of fish gonads declines after the sex differentiation period; however, information about the plasticity of the germ cells themselves after sex differentiation is limited. Using rainbow trout (Oncorhynchus mykiss), we recently established a novel germ cell transplantation system that provides a unique platform with which to dissect the developmental and cellular mechanisms ...
