The applicant has succeeded in producing infants to consider in vitro fertilization method and improvement of in vitro maturation operation using the immature oocytes, were used inbred mice. It was also acknowledged that advances the development of mature operation medium, gene expression of initial egg affects the amino acid component. The somatic cells stock to consider the establishment of the fibroblast cells by the tested small rodents further, obtained, after activation, we have succeeded in the production of cloned embryos to create a reconstructed embryos by somatic cell nuclear transfer., 研究種目:基盤研究(C); 研究期間:2011~2013; 課題番号:23500506; 研究分野:総合領域; 科研費の分科・細目:実験動物学, application/pdf}, title = {マウス遺伝資源の保全に対応した高度生殖工学技術の開発と体細胞核移植技術への応用}, year = {2013}, yomi = {アンザイ, マサユキ} }
