癌症干细胞假说对于癌症,传统的治疗方法是尽力杀死所有的癌细胞,认为只要体内有一点癌细胞尚存,癌症就有可能复发。然而20世纪六七十年代,少数科学家在实验中发现,其实肿瘤中存在的细胞群差异非常大,将它们移植到体外观察,发现它们各自形成新肿瘤的能力大不相 The Cancer Stem Cell Hypothesis For cancer, the traditional treatment is to try to kill all the cancer cells. It is believed that if there is a bit of cancer in the body, cancer may recur. However, in the 1960s and 1970s, a small number of scientists discovered in experiments that the cell populations present in tumors were very different. They were transplanted into vitro and found that their ability to form new tumors was very different.
