以前科学家们不能确认癌症是否直接起源于干细胞，或子代细胞是否是肿瘤发生的根源。
Previously scientists could not be sure if the cancer causing faults occurred directly to stem cells, or whether 'daughter' cells were the route cause of the tumour.
不仅取代功能失调或受损细胞，即所谓的再生医学，干细胞还可能为我们提供了新的前景的性质衰老和癌症。
Not only replace dysfunctional or damaged cells, the so-called regenerative medicine, stem cells may also offer us new perspectives regarding the nature of aging and cancer.
可以治愈癌症，化疗或放疗的集约利用破坏正常骨髓造血干细胞与肿瘤细胞和更换被救生。
In cancer, intensive use of chemotherapy or radiation destroys normal bone marrow along with tumor cells and replacement of blood forming stem cells can be lifesaving.
其中30％是因为艾滋病毒感染，干细胞或实体器官移植，癌症，高剂量的类固醇治疗等免疫功能低下的人。
Thirty percent of them were immunocompromised because of HIV infection, stem cell or solid organ transplantation, cancer, or high-dose steroid therapy.
通过去甲基化或重新激活DNA甲基化所沉默的肿瘤抑制基因，它们可能为干细胞重新编程和癌症研究提供非常重要的信息。
It could also inform cancer research, as it could give scientists the opportunity to reactivate tumor suppressor genes that had been silenced by DNA methylation.
干细胞本身需要接受严格的调控，调控的紊乱可能导致癌症，衰老或退行性疾病的发生。
Their dysfunction is believed to be intimately associated with various types of diseases such as cancer, degenerative diseases, and ageing, but the underlying mechanisms are poorly understood.
