    • A method of differentiation from embryo-stem cells of primates to hematogenous cells, comprising maintaining embryo-stem cells of primates under conditions suitable for differentiation-induction of hematogenous cells; transplanting obtained cells into a fetus lying in the uterus of pregnant sheep; growing the fetus to birth; administering a primates- specific cytokine to larval sheep; further growing the larval sheep to sheep; and collecting hematogenous cells of primates from the resultant sheep. There are further provided a process for producing hematogenous cells of primates; hematogenous cells produced by the process; and a method of preparing a chimeric sheep capable of producing hematogenous cells of primates, comprising maintaining embryo-stem cells of primates under conditions suitable for differentiation-induction of hematogenous cells; and transplanting obtained cells into a fetus lying in the uterus of pregnant sheep. Thus, means for treating symptoms or diseases needing setup of hematogenous system or action of hematogenous cells can be developed.

    • PURPOSE: Provided is a method for producing the transformed animals by inserting the transgene into a testicle, thereby the insertion and expression of the transgene can be faithfully reproduced. CONSTITUTION: The method for producing the transformed animals comprises the steps of: preparing the desired transgene construct consisting of the human growth hormone(hGH) gene, the hGH receptor gene, and the rat mOB gene; preparing the liposome/DNA complex by mixing the desired transgene construct with a liposome solution; inserting the liposome/DNA complex into the testicle of a Korean male sheep; harvesting the sperm of the Korean sheep inserted by the liposome/DNA complex; fertilizing a sexual excited Korean female sheep with the harvested sperm; and producing the transformed Korean sheep.
    • 目的:提供通过将转基因插入睾丸来生产转化动物的方法,从而可以忠实地再现转基因的插入和表达。 构成:生产转化动物的方法包括以下步骤:制备由人生长激素(hGH)基因,hGH受体基因和大鼠mOB基因组成的所需转基因构建体; 通过将期望的转基因构建体与脂质体溶液混合来制备脂质体/ DNA复合物; 将脂质体/ DNA复合物插入韩国雄性绵羊的睾丸中; 收获由脂质体/ DNA复合体插入的韩国羊的精子; 用收获的精子施肥性兴奋的韩国女性羊; 并生产转化的韩国羊。
