科学家创建了纳米线平台 保护天体细胞的自然形状 推进脑疾病研究 Scientists created a nanowire platform that preserves astrocytes' natural shape, advancing brain disease research.

科学家创造了一个纳米电线平台,让天体细胞、与阿尔茨海默氏和帕金森氏相连接的脑细胞在实验室研究中首次保持其自然恒星形状结构。 Scientists have created a nanowire platform that lets astrocytes, brain cells linked to Alzheimer’s and Parkinson’s, maintain their natural star-shaped structure in lab studies for the first time. 与扭曲其形状的平面不同的是,透明的纳米线垫模仿大脑组织纹理,使自然增长和分枝成为可能。 Unlike flat surfaces that distort their shape, the transparent nanowire mats mimic brain tissue texture, enabling natural growth and branching. 该系统使用无标签的3D成像,能够实时、高分辨率观测天体细胞动态。 Paired with label-free 3D imaging, the system allows real-time, high-resolution observation of astrocyte dynamics. 这一突破由约翰·霍普金斯大学和意大利国家研究委员会领导,可以推进芯片脑模型、脑有机体以及神经疾病、药物发展和脑损伤研究。 The breakthrough, led by Johns Hopkins University and the National Research Council of Italy, could advance brain-on-a-chip models, brain organoids, and research into neurological diseases, drug development, and brain injuries. 由联邦资助的研究发表在《高级科学》上。 The federally funded study was published in Advanced Science.
