The epithelium making contact with the supporting filter resembled Hertwig's epithelial root sheath. 与滤膜接触的上皮类似上皮根鞘结构。
Hertwig's epithelial root sheath, bone matrix proteins, and initiation of cementogenesis in mouse teeth 小鼠磨牙上皮根鞘与牙骨质发育的关系
AIM: To analyze the apoptosis and proliferation of HERS ( Hertwig's epithelial root sheath) and to evaluate the roles of HERS cells in the development of cementum. 目的:观察牙根发育中上皮根鞘细胞(Hertwig′sepithelialrootsheath,HERS)断裂后结局和增殖凋亡相关基因的表达,探讨上皮根鞘在牙根发育特别是牙骨质形成中的可能作用。
