BACKGROUND PreImplantation Factor (PIF), a novel peptide secreted by viable embryos is essential for pregnancy: PIF modulates local immunity, promotes decidual pro-adhesion molecules and enhances trophoblast invasion. To determine the role of PIF in post-fertilization embryo development, we measured the peptide's concentration in the culture medium and tested endogenous PIF's potential trophic ...
We recently developed an air-liquid interface long-term culture of differentiated bovine oviductal epithelial cells (ALI-BOEC). This ex vivo oviduct epithelium is capable of supporting embryo development in co-culture up to the blastocyst stage without addition of embryo culture medium. However, blastocyst rates in co-culture were markedly lower than in conventional in vitro embryo production p...
Mouse embryo culture has been established and applied in the study of the causal mechanisms of abnormal development. Mouse embryo culture can be used as an experimental system to examine the influence of teratogen on early development, together with investigations using developmental engineering such as chimera, transgenic mice and nuclear transfer. We combined mouse embryo culture with embryo ...
Immature embryo culture response of 28 durum wheat (Triticum turgidum var. durum) cultivars was studied using MS medium in Tissue Culture Laboratory of College of Agriculture, Isfahan University of Technology. Donor plants were grown in a recirculating hydroponic system and pots in a greenhouse. Regenerated immature embryos were recorded at 2, 4, 8 and 16 days after inoculation. Assessment of d...
Embryo quality is crucial to the outcome of in vitro fertilization (IVF); however, the ability to precisely distinguish the embryos with higher reproductive potential from others is poor. Morphologic evaluation used to play an important role in assessing embryo quality, but it is somewhat subjective. The culture medium is the immediate environment of the embryos in vitro, and a change of the su...
Viruses of the Russian tick-borne encephalitis complex have been reported to proliferate in chicken embryo tissue culture of Maitland type (17, 18). Recent studies on louping-ill virus have demonstrated it, s cytopathogenic effect in monolayer cultures of HeLa cells (16), Detroit 6 cells (22), and pig kidney cells (23). No eytopathogenicity has been shown with RSSE virus in skin-muscle tissue c...
