近日出版的《自然-医学》杂志报道了一种可对抗小鼠体内直肠癌干细胞的治疗药物。癌症干细胞被认为是导致耐药性和肿瘤复发的原因之一,这项新发现或有助于开发更有效的癌症治疗手段。癌症是由各类细胞种群构成,其中包括一种小而顽固的干细胞片段,这种片段能自我繁殖再生并促使更多肿瘤细胞分化产生。要想达到完全根除癌症,消灭癌症干细胞种群是一种必要途径;但是,这些干细胞所具有独特的性质让它们能够对许多癌症治疗手段产生抵抗性,这也使得它 Recently published in the “Nature - Medicine” magazine reported a mouse colorectal cancer stem cells in the treatment of drugs. Cancer stem cells are considered as one of the causes of drug resistance and tumor recurrence, and this new discovery may help to develop more effective cancer treatment. Cancer consists of a variety of cell populations, including a small but stubborn stem cell fragment that regenerates itself and causes more tumor cells to differentiate. The elimination of cancer stem cell populations is a necessary way to achieve total eradication of cancer; however, the unique nature of these stem cells allows them to be resistant to many cancer treatments, which also makes it
