Outline of Final Research Achievements |
The use of oocytes matured with mechanical vibration and fetal fibroblasts as recipients and donors, respectively, enhanced the in vitro development of Microminipig somatic cell nuclear transfer (SCNT) embryos. In addition, treatment with valproic acid (VPA) after activation increased the blastocyst formation rate of Microminipig SCNT embryos. These SCNT embryos had the ability to develop into viable piglets. The in vitro development of α-1,3-galactosyltransferase gene knockout cell-derived embryos was also enhanced by VPA treatment. Based on these results, an efficient SCNT protocol for the production of cloned Microminipigs has been established. In addition, it was suggested that this protocol can be used to create genetically modified Microminipigs.
