Acute myeloid leukemia (AML) is a polyclonal and heterogeneous hematological malignancy. Relapse and refractory after induction chemotherapy are still challenges for curing AML. Leukemia stem cells (LSCs), accepted to originate from hematopoietic stem/precursor cells, are the main root of leukemogenesis and drug resistance. LSCs are dynamic derivations and possess various elusive resistance mechanisms. In this review, we summarized different primary resistance and remolding mechanisms of LSCs after chemotherapy, as well as the indispensable role of the bone marrow microenvironment on LSCs resistance. Through a detailed and comprehensive review of the spectacle of LSCs resistance, it can provide better strategies for future researches on eradicating LSCs and clinical treatment of AML.
急性髓系白血病(AML)是一种多克隆性和异质性血液系统恶性肿瘤。诱导化疗后的复发和难治性仍然是治愈AML的挑战。白血病干细胞(LSCs)被认为起源于造血干/祖细胞,是白血病发生和耐药的主要根源。LSCs是动态衍生细胞,具有多种难以捉摸的耐药机制。在本综述中,我们总结了化疗后LSCs的不同原发性耐药和重塑机制,以及骨髓微环境对LSCs耐药的不可或缺作用。通过对LSCs耐药现象进行详细而全面的综述,可为未来根除LSCs的研究和AML的临床治疗提供更好的策略。
