    • Disclosed is a novel cell mass derived from a cancer tissue, which can reflect the in vivo behavior of a cancer cell correctly. Also disclosed is a process for preparing the cell mass. Specifically disclosed is a cell mass derived from a cancer tissue, which is an separated product that is isolated from a cancer tissue obtained from an individual as a mass containing at least three cancer cells or a cultured product of the separated product and which can retain a proliferation ability in vitro. The cell mass derived from a cancer tissue is produced by, for example, a preparation process comprising the steps of: treating a pulverized product of a cancer tissue removed from a living body with an enzyme; and selecting and collecting a mass containing at least three cancer cells among from an enzymatic treatment product.
    • 公开了一种衍生自癌组织的新型细胞团,其可以正确反映癌细胞的体内行为。 还公开了一种制备细胞块的方法。 具体公开了一种衍生自癌组织的细胞块,其是从作为含有至少三种癌细胞的质量的个体获得的癌组织分离的分离产物或分离产物的培养产物,并且可以保留 体外增殖能力。 衍生自癌组织的细胞块通过例如制备方法制备,所述制备方法包括以下步骤:用酶处理从活体中除去的癌组织的粉碎产物; 以及从酶处理产物中选择和收集含有至少三种癌细胞的物质。
