Abstract Tumor xenograft model (PDTX) derived from leukemia patients is an animal model in which the leukemia cells or primary cell lines of patients are transplanted directly into immunodeficient mice.The emergence of nude mice and SCID mice opened early xenotransplantation, then the NSG, NOG mice and the improved model and humanized mice based on there mice significantly improves the success rate of transplantation. The late presented transplantation of leukemia LSC and transplantation of patient-derived and induced pluripotent stem cells obtained based on iPSC technology provide new insight for the anderstanding leukemia genesis and development, and the new type humanized mouse model with normal lymphatic hematopoietic reconstruction provides a new platform of leukemia cell therapy and immunotherapy for leukemia therapy. PDTX is an important platform for the study of the pathogenesis and drug resistance mechanism of leukemia, as well as the development of new drugs and individualized treatment. In this paper, the recent progress in the construction and application of models of immunodeficient mice and their models is reviewed.
题目: 白血病异种移植模型的应用研究进展.
摘要: 白血病患者来源的肿瘤异种移植模型(PDTX) 是将患者白血病细胞或原代细胞系直接移植到免疫缺陷小鼠体内的动物模型。裸小鼠和SCID小鼠的出现开启了早期异种移植，随后的NSG、NOG小鼠及基于此的改进模型和人源化小鼠显著提高了移植成功率，新近出现的白血病LSC移植及基于iPSC技术衍生的患者来源诱导多能干细胞移植为白血病发生发展的认知提供了新的见解，而存在正常人淋巴造血重建的新型人源化小鼠模型为白血病细胞疗法及免疫治疗提供了新的平台。PDTX是当前研究白血病发病与耐药机制，新药开发及个体化治疗的重要平台。本文就近年来免疫缺陷鼠及其模型构建、模型应用等方面，介绍异种移植构建免疫缺陷鼠人白血病模型的最新进展。.
