人血脑屏障(BBB)是由人脑内皮细胞(hBECs)形成的选择性屏障,其对于确保足够的神经元功能和保护中枢神经系统(CNS)免受疾病的影响是重要的。因此,人体外血脑屏障模型的开发对于与CNS疾病相关的药物发现计划至关重要。在这里,我们描述了一种使用脐带血来源的造血干细胞产生人血脑屏障模型的方法。细胞最初分化成EC,然后通过与周细胞共培养诱导BBB特性。脑样内皮细胞(BLECs)表达通常在脑内皮中观察到的紧密连接和转运蛋白,并维持大多数体内BBB特性的表达至少20天。该模型是非常可重复的,因为它可以从分离自不同供体和不同实验室的干细胞中产生,并且可以用于预测化合物在人体中的CNS分布。最后,我们提供证据表明Wnt/β-catenin信号通路部分介导周细胞的BBB诱导特性。
The human blood brain barrier (BBB) is a selective barrier formed by human brain endothelial cells (hBECs), which is important to ensure adequate neuronal function and protect the central nervous system (CNS) from disease. The development of human in vitro BBB models is thus of utmost importance for drug discovery programs related to CNS diseases. Here, we describe a method to generate a human BBB model using cord blood-derived hematopoietic stem cells. The cells were initially differentiated into ECs followed by the induction of BBB properties by co-culture with pericytes. The brain-like endothelial cells (BLECs) express tight junctions and transporters typically observed in brain endothelium and maintain expression of most in vivo BBB properties for at least 20 days. The model is very reproducible since it can be generated from stem cells isolated from different donors and in different laboratories, and could be used to predict CNS distribution of compounds in human. Finally, we provide evidence that Wnt/β-catenin signaling pathway mediates in part the BBB inductive properties of pericytes.
