摘要：

The ultrastructure of secreting ameloblasts of deciduous teeth from a human foetus (crown-rump length 195 mm) was investigated. The ameloblasts demonstrate a formation of granules in a juxtanuclear Golgi complex. In the Tomes' process the granules are released either through the lateral plasma membrane into the intercellular space between the Tomes' processes or directly through the apical plasma membrane into the enamel. The human ameloblasts differ from non-human ameloblasts in having a non-oriented vesicular granular endoplasmic reticulum. Further, the majority of mitochondria are situated in the apical part of the ameloblast adjacent to the Tomes' process. © 1969 Springer-Verlag.
