Somatic cell nuclear transfer (SCNT) is an efficient technique which has been successfully applied to developmental biology, and resulted in the production of offspring from various species. It offers many opportunities in basic and medical research as well as endangered species preservation. On the other hand, embryonic stem (ES) cells are useful research tools for genetic engineering and developing disease models. In previous study, we established bovine IVF embryo derived ES cell line which can be grow indefinitely as undifferentiated cell state. In this study, we compared the effect of two different age cells (bovine ES cell; JNU-ibES-05 or adult ear fibroblast cell) on in vitro developmental potential of bovine SCNT embryo. To produce SCNT embryos, the ES cells or somatic cells were dissociated and transferred into enucleated MⅡ oocytes, and cleaved reconstructed embryos were cultured in CR1aa medium containing 10% FBS, 1 ug/ml epidermal growth factor (EGF) and 1 ug/ml insulin growth factor (IGF) for 8 days. In the result, blastocyst development rate was similar between ES cell treatment group and somatic cell treatment group, 27.7% (10/36) and 28.9% (11/ 38), respectively. However, there was particular difference in development speed from day 5 post SCNT, blastocyst expanding was 1 day faster in ES cell group than in somatic cell group. This difference was analyzed by semi-quantitative RT-PCR using pluripotency, growth and cell cycle gene markers. These results demonstrated that SCNT embryo using ES cell as a donor cell has better growth potential than somatic cell, and it will be a useful tool for a transgenic animal production.
