摘要
肿瘤干细胞是近年来在许多肿瘤组织中发现的一类特殊干细胞,具有自我更新和分化的能力,可通过不断分化为肿瘤细胞,从而形成肿瘤原发灶和转移灶.肿瘤干细胞对化疗和放疗具有很强的不敏感性,这一特性主要与其微生景中的各种分子及其相互调控有关.目前一些新型的治疗策略是针对肿瘤干细胞及其微环境所研发的新的靶向治疗方法,如抑制新生血管形成、阻止细胞发生上皮一间质转化等.深入研究肿瘤干细胞及其微生景的耐药性,可为肿瘤治疗提供新途径.
Cancer stem cells are special stem cells and are found recently in many tumors,and have the capability of self renewal and differentiation and can gradually differentiate into matured tumor cells to form the primary lesion and the various metastasis lesions of tumors.As well known,cancer stem cells shared strong ability of resistant to chemotherapy and/or radiotherapy,which is mainly related to many kinds of molecules and theirs relative regulation in niche regarding to cancer stem cells.Currently,the strategies of some novel therapies are conducted to detect the targeting sites with relevant to the microenvironments of cancer stem cells,such as the angiogenesis and epithelial-mesenchymal transition of cancer stem cells.Furthermore,insights into drug-resistance of cancer stem cells and its niche may offer new therapeutic strategies for the treatment of tumors.
