The research about interspecies somatic cell nuclear transfer to save the imminent danger animals;

Following the successful production of nuclear transfer sheep,mice,goat,cattle,porcine and rabbit et al,the inter species nuclear transfer has become one of the most attentioned questions in scientific field and international society,just because of its potential value in preserving endangered species,human embryonic stem cells research and other areas.

Influence of different parameters of electrical fusion and activation on development of porcine somatic cell nuclear transfer embryo;

Firstly,reviewed the domestic and foreign progress of transgenic cattle produced by pronuclear microinjection and somatic cell nuclear transfer,Secondly,introduced the application of the new technologies,including gene targeting,RNAi and MMCT et al,in production of transgenic cattle and safe appraisal of transgenic cattle and its products.

To examine the effects of somatic cell serial nuclear transfer (SCSNT) on buffalo somatic cell nuclear transfer (SCNT),SCSNT was conducted with the buffalo fetal cells as the donor cells.

Effects of ultraviolet irradiation on in vitro development of parthenogeneticand somatic nuclear transferred embryos in bovine;

Epigenetic modification related to somatic nuclear transfer

So the current research was designed to study main items of pig somatic nuclear transfer systematically such as somatic donors, recipient oocyte, culture of cloned embryos and embryo transfer.
