中华人民共和国科学技术部科学家开发出一种新型微流体3D血脑屏障模型
流体 神经系统 疾病
2024/9/11
血脑屏障（BBB）破坏与多种中枢神经系统疾病有关，体外BBB模型有利于研究BBB转运机制及其对外部应激事件的响应。但到目前为止，使用模型来研究BBB的能力仍然有限。2023年3月31日，苏黎世联邦理工学院的研究人员开发了一种基于人体细胞且高度集成的开放式微流体3D BBB模型，该模型带有透明的跨内皮电阻（TEER）传感器，可以实时、高分辨率地监测BBB的结构变化。研究成果发表在《Advanced ...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Layer separation for the 3D Navier-Stokes equation in a bounded domain
