A stable,rapid and effective neural differentiation method is essential for the clinical applications of human embryonic stem cells(ESCs) or induced pluripotent stem cells (iPSCs) in treating neurological disorders and diseases.Herein,we established a novel and robust monolayer differentiation method to produce functional neural progenitor cells (NPCs) from human ESC/iPSCs on Type Ⅰ Collagen.The derived cells not only displayed the requisite markers,but also behaved similarly to classic NPCs both in vitro and in vivo.Upon transplantation into traumatic brain injury model,the derived NPCs facilitated recovery from injury.We also found that SMAD signaling stayed down throughout the differentiation process on Type Ⅰ Collagen,and the pluripotent signals were rapidly downregulated along with raising up of neural early markers on the third day.Meanwhile,ATAC-seq data showed the related mediation of distinct transcriptome and global chromatin dynamics during NPC induction.Totally,our results thus provide a convenient way to generate NPCs from human ESC/iPSCs for neural diseases\' treatment.
