摘　　要：肿瘤的发生、发展与转移等生物学行为与肿瘤微环境(tumor microenvironment,TME)密切相关。TME中的非癌细胞(如成纤维细胞、免疫细胞、内皮细胞等)及细胞外基质等对肿瘤细胞的生物学行为有着极其重要的影响;TME中的生理参数(如细胞的组成和丰度、关键基因的表达等)与肿瘤的增殖、侵袭和转移密切相关。免疫治疗是一种很有潜力的肿瘤治疗方法,然而,TME的异质性可能是导致免疫耐受的原因之一。对TME的可视化研究,可直观描绘TME中不同细胞类型的动态行为,在时间与空间维度揭示TME与肿瘤生长、侵袭的协同关系,发现更多潜在的免疫治疗靶点,提高免疫治疗的有效性。因此,TME研究模型与可视化技术对于TME的可视化研究至关重要。本文主要综述了3D培养系统、类器官与人源化PDX等TME可视化研究模型以及多重免疫组织化学、多重免疫荧光、成像型质谱流式和CRISPR/Cas9基因编辑等技术在TME可视化研究中的应用进展。The tumor microenvironment(TME)describes the influence on tumor behavior of non-cancerous cells,including fibroblasts,immune cells,endothelial cells,inflammatory cells,lymphocytes,etc,and extracellular matrix that support the growth of cancer cells.The physiological parameters of TME,including the composition and abundance of cells and the expression of key genes,are closely related to tumor growth,invasion and metastasis.Immunotherapy is a currently promising approach to tumor treatment.However,the heterogeneity of TME may be one of the reasons for immune tolerance.Visualization of TME can directly depict the dynamic behavior of different cells in TME,reveal the synergistic relationship between TME and tumor growth and invasion in both spatial and temporal dimensions,discover more potential new molecular targets,and improve the effectiveness of immunotherapy.The research models and visualization technologies are very important for the visualization research of TME.Herein,we mainly reviewed the advances in research models,such as 3D culture system,organoids,and humanized PDX research model,etc,as well as the mainstream visualization technologies for TME visualization,such as immunohistochemical techniques,multiple immunofluorescence techniques,image-type mass spectrometry flow technology,and CRISPR/Cas9 genome editing technology,etc.
