    • PURPOSE: An immobilization method of bone morphogenetic proteins is provided to minimize immune reactions after bone graft by using a natural calcium chelating agent, to have excellent engraftment rate, and to improve cell suitability, biological suitability, and hydrophilicity, thereby inducing a fast bone growth. CONSTITUTION: An immobilization method of bone morphogenetic proteins comprises: a step of forming a coating layer on the surface of an implant; a step of combining chitosan or alginate as a natural calcium chelating agent on the coating layer; a step of immobilization of bone morphogenetic proteins by using diphenylphosphoryl azide, hexamethylene isocyanate, succinimide, carbodiimide glutaraldehyde or ethyl dimethylaminopropyl carbodiimide-crosslinked reagent; a step of forming hydroxyapatite or beta-tricalcium phosphate coated on the surface of titanium. The bone morphogenetic protein is selected from a group consisting of BMP-2, BMP-4, and BMP-12.

    • PURPOSE: A method for differentiating adult stem cells into schwann cells is provided to effectively differentiate adult stem cells into schwann cells without an expensive differentiation medium. CONSTITUTION: A method for differentiating adult stem cells into schwann cells using an electromagnetic field comprises the steps positioning the adult stem cells in the electromagnetic field at a frequency of 1-200 Hz; and culturing the adult stem cells. The intensity of the electromagnetic field is 0.5-2 mT. The culturing comprises the steps of: culturing the adult stem cells in an alpha-MEM medium containing beta-mercaptoethanol for 12-36 hours; culturing the adult stem cells in an alpha-MEM medium containing trans-retinoic acid for 60-82 hours; and culturing the adult stem cells in an alpha-MEM medium containing forskolin for 7-14 days.
    • 目的:提供一种将成体干细胞分化为雪旺氏细胞的方法,以有效地将成体干细胞分化成施旺细胞,而不需要昂贵的分化培养基。 构成:使用电磁场将成体干细胞分化成雪旺氏细胞的方法包括以1-200Hz的频率将成体干细胞定位在电磁场中的步骤; 并培养成体干细胞。 电磁场强度为0.5-2 mT。 培养包括以下步骤:在含有β-巯基乙醇的α-MEM培养基中培养12-36小时的成体干细胞; 在含有反式视黄酸的α-MEM培养基中培养成体干细胞60-82小时; 并在含有毛喉素的α-MEM培养基中培养成体干细胞7-14天。
