Abstract

The fine structure of secretory ameloblasts in primary tooth germs from a human fetus was investigated. Various aldehyde fixatives produced varying qualities of preservation. The morphology of the best preserved ameloblasts differed from that earlier described, mainly in the following respects: the rough endoplasmic cisternae were lamellated and regularly arranged, the mitochondria were of regular shape and size, and the ground substance was dense and homogenous. The extensive Golgi complexes, the mitochondria and the rough endoplasmic cisternae in the apical (distal) part of the ameloblast were longitudinally arranged.

摘要

对一名人类胎儿乳牙胚中分泌性成釉细胞的精细结构进行了研究。各种醛类固定剂产生的保存质量各不相同。保存最佳的成釉细胞的形态与先前描述的不同，主要体现在以下方面：粗面内质网池呈层状且排列规则，线粒体形状和大小规则，基质致密且均匀。成釉细胞顶端（远端）部分的广泛高尔基体复合体、线粒体和粗面内质网呈纵向排列。
