    • The present invention relates to a method for the isolation and cultivation of mesenchymal stem/progenitor cells from umbilical cord blood, and also to a method for the differentiation of the umbilical cord blood-derived mesenchymal stem/progenitor cells into various mesenchymal tissues. The method comprises the steps of: overlaying umbilical cord blood onto Ficoll-Hypaque solution; centrifuging the umbilical cord blood on the Ficoll-Hypaque solution to obtain a mononuclear cell layer; reacting cells obtained by monolayer culture of the mononuclear cells with antibodies to mesenchymal stem/progenitor cell-specific antigens for a predetermined period of incubation time; isolating only cells bound to their corresponding antibodies using a cell sorter; and cultivating the isolated cells, thereby obtaining mesenchymal stem/progenitor cells with high purity and excellent viability. The mesenchymal stem/progenitor cells of the present invention are capable of differentiating into various mesenchymal tissues including chondrocytes and osteoblasts. Thus, the method of cell isolation and cultivation according to the present invention allows mass production of the mesenchymal stem/progenitor cells, and the cells obtained by the present invention are useful in the renewal and treatment of injured mesenchymal tissues.
    • 本发明涉及从脐带血分离和培养间充质干细胞/祖细胞的方法,还涉及将脐带血来源的间充质干细胞/祖细胞分化为各种间充质组织的方法。 该方法包括以下步骤:将脐带血重叠在Ficoll-Hypaque溶液上; 在Ficoll-Hypaque溶液上离心脐带血,获得单核细胞层; 将单核细胞的单层培养获得的细胞与间充质干/祖细胞特异性抗原的抗体反应预定的孵育时间; 使用细胞分选器分离仅与其相应抗体结合的细胞; 并培养分离的细胞,从而获得高纯度和优良活力的间充质干细胞/祖细胞。 本发明的间充质干/祖细胞能够分化为包括软骨细胞和成骨细胞在内的各种间充质组织。 因此,根据本发明的细胞分离和培养方法允许大量生产间充质干细胞/祖细胞,并且通过本发明获得的细胞可用于损伤的间充质组织的更新和治疗。
