Optimisation of in vitro culture conditions in B6CBF1 mouse embryos.
This study was undertaken to investigate the effects of three media, volume and type of oil and frequency of observation on the in vitro development of mouse zygotes. B6CBF1 female mice (4 to 6 wk old) were superovulated using PMSG/hCG and mated with a proven fertile male of the same strain. Putative zygotes with polar bodies were collected from the oviducts of mated mice, 25-28 h after hCG inj...

Effect of Culture Conditions on Viability of Mouse and Rat Embryos Developed in Vitro
Currently in vitro culture of mouse preimplantation embryos has become a very important technique to investigate different mechanisms of early embryogenesis. However, there is a big difference in the preimplantation development between mammalian species. Despite close relatedness to mice, in vitro cultivation of rat preimplantation embryos is still delicate and needs further investigation and o...
متن کاملThe in vitro culture of primitive-streak-stage mouse embryos.
The in vitro growth and morphogenesis of mouse embryos from early primitive-streak stage to early-somite stage is described. The embryo culture method employs a static culture system, a conventional chemically defined medium (Dulbecco's modified Eagle's medium), supplemented with additional glucose, glutamine and suitably prepared serum. The method of serum preparation is important for successf...
متن کاملthe effect of culture medium volume on in vitro development of mouse embryos
background: in the field of mammalian embryo culture, the putative influence of autocrine/ paracrine factor(s), produce by the embryos itself, is under investigation. a smaller medium drop can prevent dilution of this factor(s). objective: the objective of this study was to examine the effect of culture medium volume on in vitro development of mouse 2-cell embryos. materials and methods: the em...
