淋巴瘤类器官的模型构建及应用进展

Advances in the construction and application of organoid models for lymphoma

  • 摘要: 淋巴瘤是一种具有高度异质性的恶性肿瘤,其肿瘤微环境(tumor microenvironment,TME)在疾病进展及治疗反应中发挥关键作用。然而,传统的二维细胞培养模型难以真实再现体内三维结构的复杂特性。类器官技术通过构建三维培养系统,能够更准确地模拟肿瘤的组织结构与功能特征,为淋巴瘤的研究提供了新的平台。尽管该技术前景广阔,但淋巴瘤类器官模型的建立仍面临诸多挑战,如淋巴瘤独特的生物学特性和复杂的微环境组成。本文系统梳理了淋巴瘤类器官构建过程中所面临的难点,并综述了相关方法学的最新进展。同时,回顾性分析关于淋巴瘤类器官与免疫细胞共培养的技术体系,包括原发性中枢神经系统淋巴瘤类器官和滤泡性淋巴瘤类器官的培养策略。这些研究进展显著推动了淋巴瘤研究从基础机制向临床转化的发展,促进了个性化与精准医疗的应用。

     

    Abstract: Lymphomas represent a group of highly heterogeneous malignant tumors. The tumor microenvironment (TME) surrounding these tumors plays a crucial role in disease progression and the efficacy of therapeutic interventions. Traditional two-dimensional cell culture models fail to accurately recapitulate the inherent complexity of three-dimensional (3D) in vivo architecture. Organoid technology provides a novel tool for lymphoma research, utilizing 3D culture systems to reconstruct tumor tissue organization and functionality. Despite the potential of this technology,the development of lymphoma organoid models remains a significant challenge. Developing lymphoma organoid models faces numerous hurdles, including replicating the unique biological characteristics of lymphoma and itscomplexmicroenvironment. This study provides a systematic summary of challenges associated with lymphoma organoid construction and describes recent advances in relevant methodologies. Moreover, the study further reviews recent advances in co-culture techniques combining lymphoma organoids and immune cells, including protocols for culturing patient-derived primary central nervous system lymphoma organoids and patient-derived lymphoma organoids. These advances have significantly facilitated the clinical translation of lymphoma research, transitioning it from fundamental mechanistic studies toward personalized and precision therapeutic approaches.
