effect of various concentrations of glucose on bovine cumulus-oocyte complexes maturation, fertilization and early embryonic development in vitro
background & objectives : different energy substrates and nutrients can greatly influence oocyte nuclear and cytoplasmic maturation. effect of glucose on in-vitro oocyte maturation and subsequent early embryonic development is controversial. the objective of the present study was to verify the effect of various concentrations of glucose on cumulus-oocyte complexes maturation, fertilization and ...
متن کاملCombined Effect of Retinoic Acid and Basic Fibroblast Growth Factor on Maturation of Mouse Oocyte and Subsequent Fertilization and Development
Objective Many autocrine and paracrine elements that are produced within follicular niche have been the focus of much in vitro maturation research. The present study was carried out to compare retinoic acid and basic fibroblast growth factor (bFGF) efficacy on IVM of mouse oocytes, and their further dual consumption to reach an optimal protocol. MaterialsAndMethods GV oocytes obtained from two-...
متن کاملThe effect of glucocorticoids on mouse oocyte in vitro maturation and subsequent fertilization and embryo development.
Increased glucocorticoid levels, due to medical therapy or stress-related, may affect reproduction via the hypothalamus-pituitary-axis or directly at the oocyte level. We examined the effects of natural (corticosterone) or synthetic (dexamethasone) glucocorticoids on mouse oocyte maturation and underlying changes in extracellular signal-regulated kinase (ERK) phosphorylation patterns. Fertiliza...
متن کاملEffect of Dipeptides on In vitro Maturation, Fertilization and Subsequent Embryonic Development of Porcine Oocytes
The effects of amino acids and dipeptides on in vitro production of porcine embryos and accumulation of ammonia in culture medium during developmental stages were examined in this study. The maturation, fertilization and development of embryonic cultures were performed in modified Tissue culture medium (mTCM)-199 supplemented with 10% (v/v) porcine follicular fluid, modified Tyrode's albumin la...
