| Outline of Final Research Achievements |
It is necessary for improvement of pregnancy rate in cattle to clarify the mechanisms involved in its embryo development, implantation and establishment of pregnancy. The aims of the present study are to establish the bovine induced pluripotent stem cell and induced trophoblastic cells. Bovine amnion derived cells (bADC) were introduced with transposone expression vectors (piggyBac vectors) containing doxycycline (Dox)-inducible transcription factors. Colonies were selected by morphology criteria and then their characteristics were evaluated by expression of stem cell or trophectoderm markers. We established both of bovine iPS cell lines which can be differentiated to germ cells in vivo and trophoblast cell lines which processed trophoblast stem cell-like characteristics and the potential to differentiate into the extra-embryonic cell lineage.
