Molecular markers for oocyte competence in bovine cumulus cells.
This study aimed to quantify the expression of candidate genes in cumulus cells (CCs) from cumulus-oocyte complexes (COCs) with high and low potential for in vitro development up to the blastocyst stage. First, the effects of individual culture and biopsy on embryo development were evaluated. Individuals cultured using the well of the well system were compared with individuals cultured in 20 μL...
متن کاملP-101: Developmental Competence of Bovine Vitrified GV Oocyte Selected by BCB
Background: Cryopreservation of farm animal embryos is nowadays a widely used routine technique. Success in cryopreservation of form animal depends on many factors including: freezing medium, types of cryoproctants, melting process, lipid content in ooplasm and oocyte quality It has been found that immature Oocytes with reduced reproductive performance or slaughtered at the end of their use are...
متن کاملDrosophila epigenome reorganization during oocyte differentiation and early embryogenesis.
In sexually reproducing organisms, propagation of the species relies on specialized haploid cells (gametes) produced by germ cells. During their development in the adult germline, the female and male gametes undergo a complex differentiation process that requires transcriptional regulation and chromatin reorganization. After fertilization, the gametes then go through extensive epigenetic reprog...
متن کاملOocyte activation deficiency: a role for an oocyte contribution?
BACKGROUND Infertility affects between 10 and 16% of couples worldwide. Twenty to 30% of cases of infertility are due to a male factor, 20-35% to a female factor, and 25-40% are due to both male and female factors. In ∼10-25% of cases, the precise underlying cause remains unclear. IVF or ICSI followed by embryo transfer can be very appropriate treatment options in cases of female tubal damage, ...
متن کاملRole of oocyte-derived paracrine factors in follicular development
Mammalian oocytes secrete transforming growth factor β (TGF-β) superfamily proteins, such as growth differentiation factor 9 (GDF9), bone morphogenetic protein 6 (BMP6) and BMP15, and fibroblast growth factors (FGFs). These oocyte-derived paracrine factors (ODPFs) play essential roles in regulating the differentiation and function of somatic granulosa cells as well as the development of ovarian...
