We show that diverse human tumors obtained directly from surgery or biopsy can grow at high frequency in vitro for long periods of time and still maintain many of their in vivo properties. The in vivo properties maintained in vitro include three-dimensional growth; maintenance of tissue organization and structure, including changes associated with oncogenic transformation; retention of differentiated function; tumorigenicity; and the growth of multiple types of cells from a single tumor.
我们发现,直接从手术或活检中获取的多种人类肿瘤能够在体外长时间高频生长,并且仍保持其许多体内特性。体外保持的体内特性包括三维生长;维持组织的组织学和结构,包括与致癌转化相关的变化;保留分化功能;致瘤性;以及来自单个肿瘤的多种类型细胞的生长。
