（线虫）顶乳突

The miracidium of Fasciola hepatics: The apical papilla is round and thick-walled, with the opening of the apical gland at the centre. There are 4 openings of the gland body and 6 short cilia.
肝片形吸虫毛蚴：顶突呈厚壁圆环状，中央为顶腺开口，壁上有4个腺体的开口及6根短纤毛。
It was found that apical bud and incisor papilla cells pellet developed into well-formed enamel and dentin tissues, whereas the combination of HERS cells and molar papilla cells produced bone-like dentin tissues.
结果发现：Apicalbud和切牙牙乳头细胞团形成组织结构规则的釉质和牙本质组织，HERS细胞与磨牙牙乳头细胞团形成了骨样牙本质样组织。
Introduction: Human dental apical papilla cells have mineralization potential, which play a key role in the root development of young permanent teeth.
目的：人根尖乳头细胞具有矿化潜能，它在年轻恒牙牙根的发育过程中发挥重要作用。
Limited literature is available about dental apical papilla cells mineralization in vitro and regeneration of dentin-like tissue in vivo on condition of gene transfection.
基于基因转染条件下该细胞的体外矿化能力的改变及体内牙本质样结构的形成情况少有文献报道。
