Here the authors show that active DNA damage response signaling is required both to initiate and maintain meiotic sex chromosome inactivation via a dynamic and reversible process.

In humans, the ovarian reserve is maintained over decades by meiotic arrest of oocytes. Here the authors show that Polycomb Repressive Complex 1 (PRC1)-mediated epigenetic programming is essential for formation of ovarian reserve and thus female repr

Embryo transfer uses embryos developed in vivo or in vitro for cattle production, however there is a difference in the quality of the embryos obtained by the two methods. This study addresses the differences in gene expression between blastocysts dev

Early antral follicle (EAF)-derived porcine oocytes develop more readily on polyacrylamide-gel (PAG) than on plastic plates. Xanthan gum (XG) and locust bean gum (LBG) are edible polysaccharides. We investigated XG-LBG gel supports in the development

This study compared the effects of different volumes of culture medium for the in vitro growth of oocytes derived from porcine early antral follicles (EAFs). Oocyte granulosa cell complexes (OGCs) were collected from EAFs (0.5–0.7 mm in diameter) a

Follicular fluid contains cell-free DNA (cfDNA), which may serve as a useful biomarker of oocyte ability. The present study evaluates whether nuclear and mitochondrial cfDNAs in conditioned oocyte growth medium determine the quality of oocytes cultur

Abstract Purpose Improvement of in vitro oocyte growth by addition of granulosa cells derived from differential developmental stages of follicles. Methods Granulosa cells (GCs) collected from either early antral follicles (EAFs) or antral follicles (

Background: Three-dimensional (3D) culture changes cell characteristics and function, suggesting that 3D culture provides a more physiologically relevant environment for cells compared with 2D culture. We investigated the differences in cell function

PURPOSE: The aim of the present study was to identify key microRNAs (miRNAs) in porcine follicular fluid (FF) that regulate oocyte growth. METHODS: miRNAs contained in FF were determined by small RNA-seq of exosome RNA. Upstream regulator miRNA was d
