early embryo development in transgenic SCNT embryos was compared between transgenic and non-transgenic SCNTs, parthenogenetic embryos, and in vitro fertilization (IVF) embryos. Transgenic SCNT embryos showed significantly lower rates of development to the blastocyst stage than non-transgenic ones. To investigate normal gene expression, RNA was extracted from ten blastocysts derived from parthenogenesis, IVF, non-transgenic, and transgenic SCNT embryos and reverse-transcribed to synthesize cDNA.... -

The level of P4 at the time of embryo transfer (ET) is important. P4 concentrations and numbers of corpora lutea for 126 recipients were evaluated. Nuclear transfer embryos were transferred into 126 surrogates. 11 maintained their pregnancy until full-term delivery, 17 miscarried, and implantation failed in 98 animals. P4 levels in the full-term group were significantly different from those of the pigs that aborted or in which implantation failed (p ＜ 0.05). However, the numbers of corpora... -

down-regulated by E2 in the uterus during estrus but not during proestrus or diestrus, suggesting that Enpp2 may play a role in uterine function during estrus. Enpp2 is primarily localized in the stromal cells of the endometrium during proestrus and estrus. During diestrus, Enpp2 was highly expressed in the epithelial cells of the endometrium. Taken together, these results suggest that uterine Enpp2 may be regulated by E2 and plays a role in reproductive functions during female rat development. -

effect of SNP while a SNP ＋ Hb combination reversed this effect. Nitrate and nitrite concentrations in the culture medium increased (p ＜ 0.05) in a dose- dependent manner according to SNP concentration in the culture medium. At higher concentrations, SNP had a cytotoxic effect leading to follicular oocyte apoptosis whereas lower concentrations have stimulatory effects. In conclusion, NO exerts a dual effect on its development of buffalo PFs depending on the concentration in the culture medium. -
