    • A method for preparing hyaluronic acid derivatives is provided to produce three-dimensionally porous hyaluronic acid derivatives having characteristics usable as a cell delivery carrier through wet spinning. A method for preparing hyaluronic acid derivatives includes a step of producing the derivatives of hyaluronic acid or salts thereof having excellent biocompatibility and biodegradability usable as a cell delivery carrier of a cell treatment agent comprising stem cells through wet spinning. The biocompatible hyaluronic acid threads by wet spinning are produced by using a proper mixture solution of dimethylsulfoxide and distilled water as a solvent of a spinning solution for the hyaluronic acid or salt thereof, and using ethanol, dimethylformamide, or a mixture solution thereof as a solidifying solvent.
    • 提供了一种制备透明质酸衍生物的方法,以制备具有通过湿纺丝可用作细胞递送载体的特征的三维多孔透明质酸衍生物。 制备透明质酸衍生物的方法包括制备具有优异生物相容性和生物降解性的透明质酸衍生物或其盐作为包含干细胞的细胞处理剂通过湿法纺丝的细胞递送载体的步骤。 通过使用二甲基亚砜和蒸馏水的合适的混合溶液作为透明质酸或其盐的纺丝溶液的溶剂,通过使用乙醇,二甲基甲酰胺或其混合溶液作为凝固剂,制备湿纺丝的生物相容性透明质酸线 溶剂。
