Lhx8 regulates primordial follicle activation and postnatal folliculogenesis.

ABSTRACT:

Background

The early stages of ovarian follicle formation-beginning with the breakdown of germ cell cysts and continuing with the formation of primordial follicles and transition to primary and secondary follicles-are critical in determining reproductive life span and fertility. Previously, we discovered that global knockouts of germ cell-specific transcriptional co-regulators Sohlh1, Sohlh2, Lhx8, and Nobox, cause rapid oocyte loss and ovarian failure. Also factors such as Nobox and Sohlh1 are associated with human premature ovarian failure. In this study, we developed a conditional knockout of Lhx8 to study oocyte-specific pathways in postnatal folliculogenesis.

Results

The conditional deficiency of Lhx8 in the oocytes of primordial follicles leads to massive primordial oo
