TLDR
Elucidating the nature of oocyte-somatic cell interactions at the various stages of follicle development will have important implications for the understanding of factors regulating folliculogenesis, ovulation rate and fecundity.

In vivo collection of follicular fluid and granulosa cells from individual follicles of different diameters in cattle by an adapted ovum pick-up system

TL;DR: The adapted-OPU system can be successfully used for the in vivo collection of FF and GC from follicles of different diameters from Holstein and Gir cattle and will enable further endocrine, cellular, and gene expression analyses.

Igf3: a novel player in fish reproduction

TL;DR: In this article, a novel member of the Insulin-like growth factors (Igfs) called Igf3 has been identified in teleosts of fish and the role of the Igf-type 1 receptor in mediating the action of gonadotropin through Igf type 1 receptor on several aspects of oogenesis and spermatogenesis have been demonstrated in several fish species.

FSH stimulation of anestrous cats improves oocyte quality and development of parthenogenetic embryos.

TL;DR: Ov ovarian stimulation of anestrous cats with FSH improved quality and increased the expression of LHCGR in COCs, and the enhanced in vitro developmental competence, after parthenogenetic activation of oocytes from FSH-treated cats, coincided with an increased expression of OCT4 and GATA6 in blastocyst and hatching blastocysts.
Journal ArticleDOI

New markers for regulation of transcription and macromolecule metabolic process in porcine oocytes during in vitro maturation.

TL;DR: This study performed expression microarrays to analyze the complete transcriptome of porcine oocytes during their in vitro maturation (IVM) and focused on genes belonging to ‘positive regulation of transcription, DNA-dependent’, ‘ positive regulation of gene expression’ and ‘negative regulation of macromolecule metabolic process’ ontologies.
Journal ArticleDOI

Signaling mechanisms and their regulation during in vivo or in vitro maturation of mammalian oocytes

TL;DR: In this article , the role of C-type natriuretic peptide (CNP, NPPC) produced by granulosa cells and its binding to the NPR2 receptor in cumulus cells is discussed.

Growth differentiation factor-9 is required during early ovarian folliculogenesis

TL;DR: Oocyte growth and zona pellucida formation proceed normally, but other aspects of oocyte differentiation are compromised, and GDF-9 is the first oocyte-derived growth factor required for somatic cell function in vivo.
Journal ArticleDOI

Mutations in an oocyte-derived growth factor gene (BMP15) cause increased ovulation rate and infertility in a dosage-sensitive manner.

TL;DR: It is established that BMP15 is essential for female fertility and that natural mutations in an ovary-derived factor can cause both increased ovulation rate and infertility phenotypes in a dosage-sensitive manner.

Oocyte control of ovarian follicular development and function in mammals.

John J. Eppig
- 01 Dec 2001 - 
TL;DR: The existence of an oocyte-granulosa cell regulatory loop, essential for normal follicular differentiation as well as for the production of a oocyte competent to undergo fertilization and embryogenesis, is proposed.
Journal ArticleDOI

Synergistic roles of bone morphogenetic protein 15 and growth differentiation factor 9 in ovarian function.

TL;DR: The dosage of intact Bmp15 and Gdf9 alleles directly influences the destiny of the oocyte during folliculogenesis and in the periovulatory period, which has important implications for human fertility control and the maintenance of fertility and normal ovarian physiology.

Mutations in the Genes for Oocyte-Derived Growth Factors GDF9 and BMP15 Are Associated with Both Increased Ovulation Rate and Sterility in Cambridge and Belclare Sheep (Ovis aries)

TL;DR: This is the first time that a mutation in the gene for GDF9 has been found that causes increased ovulation rate and infertility in a manner similar to inactivating mutations in BMP15, and shows that GDF 9 is essential for normal folliculogenesis in sheep.
