癌细胞是一类活细胞,它来自各种器官组织的正常细胞,其结构、组成和功能,与正常细胞有差别,有生长分裂不受控制以及与缩主关系等一系列细胞生物学的问题。国外有七、八十年实验研究的历史,特别近二、三十年来进展很快。癌细胞的研究促进了动物细胞生物学的发展。如Warburg效应与癌细胞线粒体,碳氢化合物致癌与固醇激素,突变、癌变与染色体等研究都丰富了细胞生物学的内容。虽然如此,癌生物学的一些基本问题,如癌变机理,癌细胞为什 Cancer cells are a kind of living cells. They come from normal cells of various organ tissues. Their structure, composition, and function are different from normal cells. There are a series of cell biology problems such as the uncontrolled growth and division and the relationship between them. . The history of experimental research in foreign countries for seven or eight decades has progressed rapidly in the last two to three decades. The study of cancer cells has promoted the development of animal cell biology. Such as the Warburg effect and cancer cell mitochondria, hydrocarbon carcinogenesis and steroid hormones, mutations, cancer and chromosomes and other studies have enriched the content of cell biology. Nevertheless, some basic issues of cancer biology, such as the mechanism of cancer, cancer cells
