美国《纽约时报》最近发表文章说,研究人员发现干细胞可能是癌症之源。这一发现将对癌症治疗产生深远影响。针对癌症干细胞的疗法或许疗效更为持久, 甚至能治愈转移瘤。有些学者认为,每块肿瘤的中心都有一小撮异常的干细胞,正是它们使肿瘤组织在人体内部存活下来。这种思路或许能解释肿瘤组织几乎被抗癌药全部摧毁之后为什么还能重生。另外,这还表明,我们可以制定 A recent article in the New York Times said that researchers have found that stem cells may be the source of cancer. This discovery will have a profound impact on cancer treatment. Treatments for cancer stem cells may have longer-lasting effects and can even cure metastatic tumors. Some scholars believe that each tumor has a small number of abnormal stem cells in the center of the tumor. It is precisely these that enable tumor tissues to survive inside the human body. This idea may explain why the tumor tissue can be reborn after it is almost completely destroyed by cancer drugs. In addition, it also shows that we can formulate
