越来越多的证据表明,星形胶质细胞对导致阿尔茨海默病的神经炎症和神经退行性过程的直接贡献来自啮齿动物模型的分子和功能研究。然而,这些模型可能无法完全概括人类疾病,因为人类和啮齿动物星形胶质细胞在形态、功能和基因表达方面存在很大差异。为了解决这些挑战,我们建立了一种方法,通过将人诱导多能干细胞(hiPSC)衍生的星形胶质细胞祖细胞移植到新生儿大脑中来研究小鼠大脑中的人星形胶质细胞。异种移植的hiPSC衍生的星形胶质细胞祖细胞分化成星形胶质细胞,其在功能上整合在小鼠宿主脑内,并以细胞自主的方式成熟,保留人类特异性形态、独特特征和生理特性。在阿尔茨海默氏症的嵌合体大脑中,移植的hiPSC衍生的星形胶质细胞对淀粉样蛋白斑块的存在做出反应,这些淀粉样蛋白斑块经历的形态学变化似乎与APOE等位基因背景无关。总之,我们在这里描述了一种有前途的方法,包括将患者来源的和遗传修饰的星形胶质细胞移植到小鼠大脑中,以研究阿尔茨海默病背景下的人类星形胶质细胞病理生理学。在线版本包含补充材料,可通过10.1186/s13024-021-00487-8获得。
Increasing evidence for a direct contribution of astrocytes to neuroinflammatory and neurodegenerative processes causing Alzheimer’s disease comes from molecular and functional studies in rodent models. However, these models may not fully recapitulate human disease as human and rodent astrocytes differ considerably in morphology, functionality, and gene expression. To address these challenges, we established an approach to study human astrocytes within the mouse brain by transplanting human induced pluripotent stem cell (hiPSC)-derived astrocyte progenitors into neonatal brains. Xenografted hiPSC-derived astrocyte progenitors differentiated into astrocytes that integrated functionally within the mouse host brain and matured in a cell-autonomous way retaining human-specific morphologies, unique features, and physiological properties. In Alzheimer´s chimeric brains, transplanted hiPSC-derived astrocytes responded to the presence of amyloid plaques undergoing morphological changes that seemed independent of the APOE allelic background. In sum, we describe here a promising approach that consist of transplanting patient-derived and genetically modified astrocytes into the mouse brain to study human astrocyte pathophysiology in the context of Alzheimer´s disease.
