    • PROBLEM TO BE SOLVED: To provide a new pretreatment method and application of biomaterial contributing to regeneration medical treatment and cell medical treatment. SOLUTION: A method for preparing an artificial bone unit containing cells pretreated so as to be able to be applied to a living body by agitatably mixing micromoldings into the suspension liquid of cells capable of expressing a hard tissue forming relating function is characterized of (1)preparing a cell suspension liquid of a predetermined cell concentration using the cells, (2)mixing a plurality of micromoldings into the cell suspension liquid to make the micromoldings trap the cells within the suspension liquid, (3)stationarily placing the micromoldings trapping the cells in a culturing environment or a cell differentiation environment, (4)forming micromoldings or cell complex bodies by culturing until a part or whole of the cells trapped by the micromoldings forms cell aggregated masses, and (5)preparing the artificial bone unit containing the cells capable of being applied in the living body by the above (1) to (4). And the artificial bone unit containing the cells is also disclosed. COPYRIGHT: (C)2005,JPO&NCIPI
    • 要解决的问题:提供一种新的预处理方法和有助于再生医疗和细胞治疗的生物材料的应用。 解决方案:一种制备人造骨单元的方法,其特征在于,含有预处理细胞以能够通过将微胶囊搅拌混合到能够表达硬组织形成相关功能的细胞的悬浮液中而应用于生物体的人造骨单元的特征在于 (1)使用所述细胞制备预定细胞浓度的细胞悬浮液,(2)将多个微胶囊混合到细胞悬浮液中,使微胶囊捕获悬浮液中的细胞,(3)静置放置微胶束捕获 在培养环境或细胞分化环境中的细胞,(4)通过培养形成微型胶原或细胞复合体,直到被微胶囊捕获的细胞的一部分或全部形成细胞凝集物质,和(5)制备含有 能够通过上述(1)〜(4)将生物体施用于细胞的细胞。 还公开了含有细胞的人造骨单元。 版权所有(C)2005,JPO&NCIPI
