Neural crest stem cells (NCSCs) represent a transient and multipotent cell population that contributes to numerous anatomical structures such as peripheral nervous system, teeth, and cornea. NCSC maldevelopment is related to various human diseases including pigmentation abnormalities, disorders affecting autonomic nervous system, and malformations of teeth, eyes, and hearts. As human pluripotent stem cells including human embryonic stem cells (hESCs) and human induced pluripotent stem cells (hiPSCs) can serve as an unlimited cell source to generate NCSCs, hESC/hiPSC-derived NCSCs can be a valuable tool to study the underlying mechanisms of NCSC-associated diseases, which paves the way for future therapies for these abnormalities. In addition, hESC/hiPSC-derived NCSCs with the capability of differentiating to various cell types are highly promising for clinical organ repair and regeneration. In this review, we first discuss NCSC generation methods from human pluripotent stem cells and differentiation mechanism of NCSCs. Then we focus on the clinical application potential of hESC/hiPSC-derived NCSCs on peripheral nerve injuries, corneal blindness, tooth regeneration, pathological melanogenesis, Hirschsprung disease, and cardiac repair and regeneration.
神经嵴干细胞(NCSCs)是一种短暂存在的多能细胞群体,它对众多解剖结构的形成有贡献,如外周神经系统、牙齿和角膜。NCSC发育异常与多种人类疾病相关,包括色素沉着异常、影响自主神经系统的疾病以及牙齿、眼睛和心脏的畸形。由于包括人类胚胎干细胞(hESCs)和人类诱导多能干细胞(hiPSCs)在内的人类多能干细胞可以作为产生NCSCs的无限细胞来源,hESC/hiPSC来源的NCSCs可以成为研究NCSC相关疾病潜在机制的宝贵工具,这为未来治疗这些异常情况铺平了道路。此外,具有分化为各种细胞类型能力的hESC/hiPSC来源的NCSCs在临床器官修复和再生方面极具前景。在本综述中,我们首先讨论从人类多能干细胞生成NCSCs的方法以及NCSCs的分化机制。然后我们重点关注hESC/hiPSC来源的NCSCs在外周神经损伤、角膜盲、牙齿再生、病理性黑素生成、先天性巨结肠病以及心脏修复和再生方面的临床应用潜力。
