Abstract

Reproductive technologies including in vitro fertilization (IVF), embryo manipulation, gamete and embryo freezing, thawing and embryo transfer were rapidly developed. Vitrification is an embryo freezing technique that is the most developed. In this experiment, we vitrified mouse embryos and then examined the embryos i.e: (i) the quality of the embryos after thawing, (ii) the implantation rate of the embryos and (iii) viability of the embryos in vivo. Morulae and blastocycsts were collected from female mice that were pregnant a day 3,5. The embryos were equilibraten in mPBS +10% etilene glycol. Vitrification was carried out by using VABEDS medium, containing 6-10 embryos that were dropped into a tip of a straw, then frozen in liquid nitrogen for 24 hours. Thawing was carried out by flushing the embryos using mPBS suplemented with 0.5, 0.25, 0.1 and 0 M sucrose. After being incubated in M2 medium at 37oC for 1-2 hours, the recovery embryos were then transferred into the uteri of day 2.5 of pseudopregnat females. The females were then sacrificed at day 16 of gestation and the total implantaion, total life and death fetuses, as well as resorpted embryos, were taken as data. The results showed that vitrification significantly (p<0,05) reduced the quality of the embryos, as well as their implantation rate and the viability of the fetuses, which may be caused by the unoptimal combination of the cryoprotectant in the vitrification medium, temperature and exposure time during vitrification.

Abstract

Maternal contribution to and direct action of methoxyacetic acid (MAA) on the embryonic development bad been examined by conducting embryo transfer. To reveal the maternal contribution, compacted morulae and early blastocysts, which were collected from untreated Swiss Webster donor mice on day 3 of gestation, were transferred to day 2 pseudopregnant recipients, after having been treated with 2.0 mmo/lkg body weight (b.w.) MAA by gavage on day 1 of pseudopregnancy. Direct effect of MAA on the embryonic development were observed by transferring compacted morulae and early blastocysts, similarly recovered from day 3 pregnant donor mice, after MAA treatment on day 2 of gestation with the same method and dosing, to untreated day 2 pseudopregnant recipients. Control donor mice and recipient were given distilled water only as the MAA solvent. Observations on fetuses resulting from embryo transfer wert: carried out on day 16 of gestation . Administration of MAA to the donors tended to decrease the unplantatlon rate and the survival rate of the implanted embryos. When MAA was given to the recipients the implantation rate and survival rate of embryos transferred decreased significantly (p<0.05) but the survival rate of implanted embryos were significantly higher (p<0.05) Lf compared to those of MAA treated donors. The intrauterine death tended to inc rease either in the treated donors or recipients. There was no effect of MAA on the fetal body weight and in producing fetal malformations. It is concluded that at the beginning of implantation, maternal contribution in revealing the effects of MAA on the embryonic development of Swiss Webster mice is predominant, whereas after implantation took place, the quality of the embryos become more important for their survival.
