    • PURPOSE: A transgenic cloned pig producing human erythropoietin and a method for producing the same transgenic cloned pig are provided, thereby producing a large quantity of human erythropoietin in the urinary bladder of the transgenic cloned pig with reduced costs. CONSTITUTION: The nuclear transfer embryo produced by a fusion of a pig-derived enucleated oocyte with a nucleus of a pig-derived somatic cell transfected and targeted with a gene encoding human erythropoietin is provided. The transgenic cloned pig expresses human erythropoietin in the urinary bladder of pig. The method for producing a transgenic cloned pig producing human erythropoietin comprises the steps of: (a) transfecting and targeting a gene encoding human erythropoietin into a pig-derived somatic cell line to prepare a nuclear donor cell; (b) removing cumulus cells surrounding a recipient oocyte and then the cytoplasm including the first polar body from the oocyte to prepare a pig-derived enucleated recipient oocyte; (c) transferring the transfected nuclear donor cell into the enucleated recipient oocyte and carrying out cell fusion to generate nuclear transfer embryos; and (d) transplanting the nuclear transfer embryo into a surrogate mother pig to produce live offspring.
    • 目的:提供产生人促红细胞生成素的转基因克隆猪和产生相同转基因克隆猪的方法,从而以降低的成本在转基因克隆猪的膀胱中产生大量人促红细胞生成素。 构成:提供了通过将猪衍生的去核卵母细胞与转染并用编码人红细胞生成素的基因靶向的来源于体细胞的细胞核的融合产生的核转移胚。 转基因克隆猪在猪的膀胱中表达人促红细胞生成素。 生产人促红细胞生成素的转基因克隆猪的方法包括以下步骤:(a)将编码人促红细胞生成素的基因转染并靶向猪衍生的体细胞系以制备核供体细胞; (b)去除卵母细胞周围的卵丘细胞,然后从卵母细胞中除去包括第一极体的细胞质,以制备猪衍生的去核受体卵母细胞; (c)将转染的核供体细胞转移到去核的受体卵母细胞中并进行细胞融合以产生核转移胚胎; 和(d)将核转移胚胎移植到替代母猪中以产生活的后代。

    • PURPOSE: A method for production of cloned animal embryos by nuclear transfer is provided to reduce the number of cloning processes. Therefore, itt can be useful for preservation of animals threatened with extinction, production of useful proteins, development of disease model, and supply of deficient organs. CONSTITUTION: The method for production of cloned animal embryos by nuclear transfer comprises the steps of: (i) inhaling a first polar body and 10 to 20% of cytoplasm without dying the nuclear of an egg cell by using a glass pipe having diameter of 20 to 40 micrometer to remove the nuclear from the egg cell; (ii) introducing a somatic cell into the first polar body and nuclear removed egg cell to prepare an egg-somatic cell complex within 1 minute during the inhalation process; and (iii) subjecting the egg-somatic cell complex to electric stimulation of 0.5 to 2 kv/cm and 6 to 150 microseconds 1 to 3 times to fuse and activate the egg-somatic cell complex, wherein the egg cell is collected from a mammal selected from pig, cow, sheet, mouse, rat, rabbit, dog and cat.
    • 目的:提供通过核转移生产克隆动物胚胎的方法,以减少克隆过程的数量。 因此,它可以用于保护受灭绝威胁的动物,生产有用的蛋白质,发展疾病模型和供应不足的器官。 构成:通过核转移生产克隆动物胚胎的方法包括以下步骤:(i)通过使用直径为20的玻璃管,吸入第一极体和10-20%细胞质而不致死卵细胞核 至40微米,以从卵细胞中除去核; (ii)在吸入过程中在1分钟内将体细胞引入第一极体和核移除的卵细胞中以制备卵体细胞复合物; 和(iii)使卵体细胞复合物经受0.5至2kv / cm和6至150微秒的电刺激1至3次以融合并活化卵体细胞复合物,其中从哺乳动物收集卵细胞 选自猪,牛,片,鼠,大鼠,兔,狗和猫。
