Biodiversity is defined as the presence of a variety of living organisms on the Earth that is
essential for human survival. However, anthropogenic activities are causing the sixth mass …

During the last 2 decades, research on in vitro preantral follicle growth and oocyte
maturation has delivered fascinating advances concerning the knowledge of processes …

The pituitary gonadotropin FSH is a glycoprotein critical for the development of ovarian
follicles. Upon binding to its G protein-coupled membrane receptor located on the granulosa …

The regulation of folliculogenesis involves a complex interaction among endocrine,
paracrine and autocrine factors. The mechanisms involved in the initiation of the growth of …

The aim of this study was to evaluate the development and estradiol production of isolated
bovine secondary follicles in two-dimensional (2D, experiment 1) and three-dimensional (3D …

The limitation in the supply of mature, fertilisable oocytes constitutes a major impediment to
increasing the success of assisted reproduction, stem cell derivation and cloning in domestic …

During the reproductive lifespan of a female, only a limited quantity of oocytes are naturally
ovulated; therefore, the mammalian ovary possesses a substantial population of preantral …

Contents Stem cells have been isolated from ovaries, and their ability to differentiate into
oocytes in vitro has been demonstrated for mice and human, but not for bovine species. The …

Purpose The study investigated potential correlations between the expression levels of
ADAMTS1 and HSPG2 in cumulus cells (CCs) and controlled ovarian hyperstimulation …

This study evaluated the effect of bone morphogenetic proteins 2 (BMP2) and 4 (BMP2) on
follicle development and mRNA expression for GDF9, Cyclin B1, BMPR1A, BMPR1B …
