随着成釉器的发育,内釉细胞开始分化为成釉细胞(ameloblast),该细胞呈高柱状,高达40um,直径4-5um.细胞与中间层细胞以桥粒相连. 在分泌活动开始前,细胞器重新定位,即细胞核远离基底膜;高尔基复合体体积增大,从细胞的近端向基底膜端移动,

antiparallel：反向平行

虽然DNA分子的两条链互补,但方向不同,是互为反向平行(antiparallel)的,一条链的5-端与互补链的3-端相对应,反之亦然. 所以,若一条链的碱基序列是5-ATGCGCTGA-3',则另一条链将是3-TACGCGACT-5'. 细胞内大多数涉及DNA的反应过程都沿5-端到3-端进行的,

senescence：细胞衰老

细胞自杀是细胞衰老(senescence)之外,另一种可选择的命运. 每次细胞分裂时端粒都会缩短,变到足够短会促使细胞自杀. 这种细胞死亡过程是自然的,出错会导致无法控制的细胞生长. 端粒酶能够维持生命通常与衰退,能力丧失联系在一起,
