胶质母细胞瘤表现出巨大的瘤内和瘤内异质性,使有效治疗策略的发展复杂化。目前的体外模型在保留亲本肿瘤的细胞和突变多样性方面存在局限性,并且需要较长的世代时间。在这里,我们报告了产生和生物库患者衍生的胶质母细胞瘤类器官(GBOS)的方法,它概括了相应亲代肿瘤的组织学特征、细胞多样性、基因表达和突变特征。将GBOS移植到成年啮齿动物脑内,可以快速、可靠地生成GBOS,并表现出快速、侵袭性的渗透。我们通过将GBO突变特征与特定药物的反应相关联,并通过对嵌合抗原受体T细胞免疫治疗进行建模,进一步证明了GBOS在测试个性化治疗中的有效性。我们的研究表明,GBOS保留了胶质母细胞瘤的许多关键特征,并可以迅速应用于研究患者特定的治疗策略。此外,我们的活生物库为基础和翻译的胶质母细胞瘤研究建立了丰富的资源。一种快速而可靠的方法来生成患者来源的胶质母细胞瘤器官样物质,捕捉其各自亲代肿瘤的特征和多样性,以允许测试与有机样物质特征相关的个性化治疗,并为进一步的基础和翻译胶质母细胞瘤研究建立生物库。
Glioblastomas exhibit vast inter- and intra-tumoral heterogeneity, complicating the development of effective therapeutic strategies. Current in vitro models are limited in preserving the cellular and mutational diversity of parental tumors and require a prolonged generation time. Here, we report methods for generating and biobanking patient-derived glioblastoma organoids (GBOs) that recapitulate the histological features, cellular diversity, gene expression, and mutational profiles of their corresponding parental tumors. GBOs can be generated quickly with high reliability and exhibit rapid, aggressive infiltration when transplanted into adult rodent brains. We further demonstrate the utility of GBOs to test personalized therapies by correlating GBO mutational profiles with responses to specific drugs and by modeling chimeric antigen receptor T cell immunotherapy. Our studies show that GBOs maintain many key features of glioblastomas and can be rapidly deployed to investigate patient-specific treatment strategies. Additionally, our live biobank establishes a rich resource for basic and translational glioblastoma research. A rapid and reliable method to generate patient-derived glioblastoma organoids captures the features and diversity of their respective parental tumors to allow for testing personalized therapies correlated to organoid profile and the establishment of a biobank for further basic and translational glioblastoma research.
