Odontoblast in tooth development - mammalian embryo

Scheme electronmicroscopy. A columnar and irregular shaped cell (mesenchymal origin) with a taperwise odontoblastic process within the predentin. The bottom side is adjacent to the future pulp cells. The cell body contains many organelles and especially a well-developed Golgi area with prosecretoy granules. A cell web delimits the process from the supranuclear cytoplasm and laterally small junctional complexes (gap junctions) are localized.
