    • A mesonephric stem cell line is provided to be differentiated into various cells, treat various diseases or disorders through cell therapy and be used for developing a transgenic animal used for xenotransplantation. A method for preparing a mesonephric stem cell line comprises the steps of: (a) obtaining a mesonephric stem cell from mesonephros of mammal; (b) culturing the mesonephric stem cell onto a feeder cell layer to form a colony; and (c) subculturing the colony to obtain the mesonephric stem cell line, wherein the mammal is human, pig, cattle, sheep, horse, rabbit, goat, mouse, hamster or rat and the feeder cell layer is a fibroblast layer. A mesonephric stem cell line is derived from the mesonephros of the mammal and is characterized in that it show a positive reaction regarding alkaline phosphatase and has the ability of being naturally differentiated into embryonic bodies. Further, the fibroblast is derived from ICR mouse, and a number of the fibroblast is 1.8 to 2.8x10^5 cell/ml.

    • PURPOSE: A medium composition and culture method for improving preimplantation development of clone embryo are provided, thereby effectively inhibiting apoptosis of blastomere to improve preimplantation development of clone embryo, thereby improving the production yield of health clone embryo. CONSTITUTION: The medium composition for in vitro culturing the nucleus transferring somatic cell for preparing clone embryo contains 1-25 micromole of antibiotics such as beta-mercaptoethanol, and 1-10 microgram/milliliter of an oxidized nitrogen removing factor such as hemoglobin. The method for in vitro culturing the clone embryo in the medium composition comprises the steps of: (a) in vitro culturing the nucleus transferring somatic cell in the in vitro culturing medium composition containing antibiotics; (b) transplanting the nucleus of the nucleus transferring somatic cell to a nucleus receiving egg of which genetic materials are removed to prepare somatic cell clone embryo; and (c) in vitro culturing the somatic cell clone embryo in the in vitro culturing medium composition containing antibiotics and oxidized nitrogen removing factor.
    • 目的:提供一种改善克隆胚胎植入前发育的培养基和培养方法,有效抑制卵裂球细胞凋亡,改善克隆胚胎植入前的发育,提高了克隆胚胎的产量。 构成:用于体外培养转运体细胞以制备克隆胚胎的培养基组合物含有1-25微摩尔的抗生素如β-巯基乙醇和1-10微克/毫升的氧化除氮因子如血红蛋白。 在培养基组合物中体外培养克隆胚胎的方法包括以下步骤:(a)体外培养在含有抗生素的体外培养培养基组合物中转运体细胞的细胞核; (b)将转移体细胞的细胞核移植到接受蛋的细胞核,其中遗传物质被去除以制备体细胞克隆胚胎; 和(c)在含有抗生素和氧化除氮因子的体外培养培养基组合中体外培养体细胞克隆胚胎。
