在胚胎的发育中 ,神经嵴细胞是一组特殊的细胞群 ,可以分化为神经元、神经胶质细胞及多种非神经细胞 ,是机体内最具多能性的结构之一。在口腔颌面部的发育中 ,大部分组织如牙乳头、牙囊、牙周膜、骨组织、肌肉中所包含的细胞几乎无一例外地均来源于神经嵴细胞[1] 。因此 ,神经? In embryonic development, neural crest cells are a special group of cells that can differentiate into neurons, glial cells and many non-neuronal cells, and is one of the most pluripotent structures in the body. In the development of oral and maxillofacial regions, most of the tissues such as papilla, periodontal ligament, periodontal ligament, bone tissue, and muscle contain almost all cells derived from neural crest cells [1]. So nerves?
