研究揭示神经发育障碍的表型脑类器官图谱和生物库

加州大学Joseph G. Gleeson小组宣布他们研发了神经发育障碍的表型脑类器官图谱和生物库。2025年11月3日,国际知名学术期刊《细胞—干细胞》发表了这一成果。

为了填补这些空白,研究组提出了一个由加州再生医学研究所(CIRM)发起的NDD生物库,其中包含352个公开可用的遗传多样性患者来源的诱导多能干细胞(iPSCs),以及临床细节、脑成像和基因组数据,代表了它们的主要疾病类别:小头畸形(MIC)、多小回症(PMG)、癫痫(EPI)和智力残疾(ID)。从35名代表性患者中,该团队研究了6000多个脑类器官的组织学和单细胞转录组学。与来自10个典型神经系统的类器官文库相比,患者表现出与潜在临床疾病类别相关的明显细胞缺陷。MIC表现为细胞存活缺陷,TTR+细胞过多,PMG表现为中间祖细胞连接缺陷,EPI表现为星形胶质细胞过多,ID表现为TTR+细胞过量生成。他们的类器官图谱显示了保守的和不同的NDD类别特异性表型,桥接基因型和表型。这个NDD iPSC生物库可以支持未来的疾病建模和治疗方法。

据了解,基因的缺失与神经发育障碍(NDDs)有关,但机制和靶向治疗仍不清楚。

Abstract: Thousands of genes are associated with neurodevelopmental disorders (NDDs), yet mechanisms and targeted treatments remain elusive. To fill these gaps, we present a California Institute of Regenerative Medicine (CIRM)-initiated NDD biobank of 352 publicly available genetically diverse patient-derived induced pluripotent stem cells (iPSCs), along with clinical details, brain imaging, and genomic data, representing four major categories of disease: microcephaly (MIC), polymicrogyria (PMG), epilepsy (EPI), and intellectual disability (ID). From 35 representative patients, we studied over 6,000 brain organoids for histology and single-cell transcriptomics. Compared with an organoid library from ten neurotypicals, patients showed distinct cellular defects linked to underlying clinical disease categories. MIC showed defects in cell survival and excessive TTR+ cells, PMG showed intermediate progenitor cell junction defects, EPI showed excessive astrogliosis, and ID showed excessive generation of TTR+ cells. Our organoid atlas demonstrates both conserved and divergent NDD category-specific phenotypes, bridging genotype and phenotype. This NDD iPSC biobank can support future disease modeling and therapeutic approaches.
