成牙本质细胞的基本特征及其研究进展

成牙本质细胞作为牙髓细胞的主要成分，具有在牙发育期间和成熟牙内生成牙本质的功能。目前的研究多基于牙髓细胞的二维体外培养，随着对牙髓组织研究的不断深入，牙髓细胞体外三维立体模型的建立将是未来研究的热点。作者回顾了近年来对成牙本质细胞的研究情况，主要阐述了成牙本质细胞的形态、超微结构、功能、蛋白表达的特征及其研究进展和今后的研究方向。

The basic characters and research advancements of odontoblasts

As the main components of dental pulp cells,the odontoblasts were responsible for the formation and maintenance of dentin during the development and mature age of teeth.Presently the studies were mostly based on the two-dimensional vitro cultured technique,but with the developing research of pulp tissue, three-dimensional vitro cultured technique will be the study hotspot in future.The author retrospected the investigation about the odontoblasts these years and mostly expatiated the morphology,ultrastructure,function and characters of protein expression about the odontoblasts,including the research advancements and research aspects in future.
