摘要
Over the past few decades,high-throughput screening(HTS)has made great contributions to new drug discovery.HTS technology is equipped with higher throughput,minimized platforms,more automated and computerized operating systems,more efficient and sensitive detection devices,and rapid data processing systems.At the same time,in vitro neurogenesis is gradually becoming important in establishing models to investigate the mechanisms of neural disease or developmental processes.However,challenges remain in generating more mature and functional neurons with specific subtypes and in establishing robust and standardized three-dimensional(3D)in vitro models with neural cells cultured in 3D matrices or organoids representing specific brain regions.Here,we review the applications of HTS technologies on in vitro neurogenesis,especially aiming at identifying the essential genes,chemical small molecules and adaptive microenvironments that hold great prospects for generating functional neurons or more reproductive and homogeneous 3D organoids.We also discuss the developmental tendency of HTS technology,e.g.,so-called next-generation screening,which utilizes 3D organoid-based screening combined with microfluidic devices to narrow the gap between in vitro models and in vivo situations both physiologically and pathologically.
