 Developments research have made culturing human embryos beyond the 14-day limit seem technologically feasible. In article “Emerging Human Embryo Research Technologies, Rule, and Special Status of Embryo,” authors examine a proposal for new embryo embryoid guidelines by reviewing history emerging areas that are impacted these...

background: the basal medium that supports isolated mouse oviduct (imo) is important for supporting embryo development and quality. methods: the culture of ovine ivm/ivf zygotes was done in imo using sofaacibsa and sofaabsa as basal medium of imo and in sofaabsa alone as control. for preparation of imo mature inbred strain c57bl/6 female mice were synchronized and mated with vasectomized males....

mouse embryos into blastocysts in vitro have been closely examined (Whitten, 1956, 1957; Brinster, 1965a, b, c), and it has been shown that the requirements depend on the stage of development when cultivation begins (Brinster & Thomson, 1966; Biggers, Whittingham & Donahue, 1967). One of the inter¬ esting findings has been that there is no absolute requirement for the essential amino acids eith...

Background: There are different etiological factors in spontaneous recurrent abortion which are one of the complications in pregnancy. Primary embryo development in uterine tube and oviduct are affected by different factors such as embryotrophic elements. ETF3 as a embryotrophic factor that contains a complex of complement 3 protein and its derivatives specially iC3b, causes embryo trophoblast ...

BACKGROUND High concentration of glucose in culture medium affects the developmental process and the quality of the pre-implantation embryo. This study examined the effects of Zuogui Wan (ZGW) supplementation on early embryo development cultured in high-glucose medium. METHODS Embryos were cultured in high-glucose medium with or without ZGW supplementation. Developmental rate and competence w...
