Human pluripotent stem cells (hPSCs) have shown the ability to self-organize into different types of neural organoids (e.g., whole brain organoids, cortical spheroids, midbrain organoids etc.) recently. The extrinsic and intrinsic signaling elicited by Wnt pathway, Hippo/Yes-associated protein (YAP) pathway, and extracellular microenvironment plays a critical role in brain tissue morphogenesis. This article highlights recent advances in neural tissue patterning from hPSCs, in particular the role of Wnt pathway and YAP activity in this process. Understanding the Wnt-YAP interactions should provide us the guidance to predict and modulate brain-like tissue structure through the regulation of extracellular microenvironment of hPSCs.
人类多能干细胞(hPSCs)近来已显示出能够自我组织形成不同类型的神经类器官(例如,全脑类器官、皮质球体、中脑类器官等)的能力。Wnt信号通路、Hippo/Yes相关蛋白(YAP)信号通路以及细胞外微环境引发的外在和内在信号传导在脑组织形态发生中起着关键作用。本文重点介绍了hPSCs在神经组织模式形成方面的最新进展,特别是Wnt信号通路和YAP活性在此过程中的作用。了解Wnt-YAP相互作用应该能为我们通过调控hPSCs的细胞外微环境来预测和调节类脑组织结构提供指导。
