    • PURPOSE: An improved method of intracytoplasmic sperm injection is provided, thereby reducing the medium amount used, inhibiting damage of oocyte and inducing mechanical damage of the sperm head membrane, so that the fertilization success rate can be improved. CONSTITUTION: An injection pipette having the diameter which is larger than the maximum head diameter of sperms to be introduced into the oocyte cytoplasm and is smaller than the maximum tail diameter of sperms is used in the intracytoplasmic sperm injection(ICSI), wherein the end of the pipette has a plurality of spikes. The improved method of intracytoplasmic sperm injection comprises the steps of: collecting a sperm with the injection pipette; introducing the sperm into the oocyte cytoplasm; and recovering the injection pipette, wherein the sperm head is collected by the tip of the injection pipette.
    • 目的:提供细胞质内精子注射的改进方法,减少使用的培养基,抑制卵母细胞的损伤,诱导精子头膜的机械损伤,从而提高受精成功率。 构成:在细胞质内精子注射(ICSI)中使用直径大于要引入卵母细胞的精子的最大头部直径并且小于精子的最大尾部直径的注射移液管,其中末端 移液管具有多个尖峰。 细胞质内精子注射的改进方法包括以下步骤:用注射移液管收集精子; 将精子引入卵母细胞质中; 并回收注射移液管,其中精子头被注射移液管的尖端收集。

    • 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。
