Background: Because of the protection of surplus embryos, Cryopreservation is usually used in ART. It is not clear, the vitrified-warmed embryos that have normal morphology, be normal in genetic level, too. DNA methylation of gene regulatory regions can causes inhibition of gene expression. We study effect of vitrification method of cryopreservation on DNA methylation and gene expression level ...
The efficiency of a porcine embryo vitrification method that uses water-soluble films of pullulan, a naturally-occurring polysaccharide polymer, was compared with two other types of vitrification methods using different devices and solutions for vitrification and warming. Blastocysts collected in vivo and vitrified by the conventional straw (ST), Cryotop((R)) (MVC) or pullulan film vitrificatio...
Abstract The African lion is an excellent model species for the highly endangered Asiatic lion. lions reproduce well in zoos, leading to fact that occasionally ovaries and testis are available in-vitro experiments. We previously performed maturation (IVM) fertilization of oocytes were able produce advanced embryos after intracytoplasmic sperm injection (ICSI) with cryopreserved sperm. Here we e...
