SummaryThe beneficial effect of supplementing culture medium with melatonin has been reported during in vitro embryo development of species such as mouse, bovine and porcine. However, the effect of melatonin on mouse somatic cell nuclear transfer rem

After screening 408 crude drugs, we found that Rizoma Arisaematis increased the cell numbers of mouse blastocysts developed from in vivo zygotes. We examined the effects of Rizoma Arisaematis on the in vitro development of mouse zygotes and embryos p

As reported previously, berberine, the main component extracted from Coptis rhizome and Phellodendron, has potential as a contraceptive for animals since berberine has a strong inhibitory effect on the in vitro development of mouse zygotes and on fet

In our previous study (Tsuji et al., 2010 ), administration of hCG to recipients around the timing of implantation significantly increased the in vivo development of mouse embryos after somatic cell nuclear transfer (SCNT) until day 10.5, but did not

Cloning efficiency has not been dramatically improved after the first success of somatic cell nuclear transfer (SCNT) in sheep in 1997. The reasons for the low efficiency of SCNT embryos must be attributed to the insufficient reprogramming of the don

We examined the optimal conditions for somatic cell nuclear transfer (SCNT) in rat oocytes. First, we compared the effects of two types of inhibitors of spontaneous activation, MG132 and demecolcine, on the developmental potential of parthenogenetic

The effect of removing cytoplasmic lipid droplets (delipidation) at the 2-cell and developmental stages on the survival of porcine somatic cell nuclear-transferred blastocysts developed from the enucleated oocytes receiving somatic cells from kidney

Parthenogenetic activation is an important factor in successful production of cloned mammals. Because it has been reported that aged oocytes are more sensitive to parthenogenetic activation than young oocytes, the present study examined the effects o

The evaluation of embryo morphology, widely used for selecting mammalian embryos before transfer, is not an adequate standard for selecting nuclear-transferred (NT) embryos. To search for markers useful for predicting the potential of NT embryos to d

Before fertilization, chromatins of both mouse oocytes and spermatozoa contain very few acetylated histones. Soon after fertilization, chromatins of both gametes become highly acetylated. The same deacetylation-reacetylation changes occur with histon
