Tooth Germ in Tissue Culture

Scanning electron microscopic observations of tooth germ in tissue culture with special reference to the migration of epithelial cells.

Tooth germ derived from the mandible of newborn mice was used in this study. The enamel organs were dissected and attached directly to coverslips without using the plasma clot. By this method it was possible, for the first time as far as is known, to attain preparations in which the major part of the outgrowth from the explant consisted purely of epithelial-like cells which probably were anelob...

Analysis of the Development of a Chimeric Bioengineered Tooth Germ in in Vitro Organ Culture

Collagen analysis in human tooth germ papillae.

The extracellular matrix (ECM) performs a very important role in growth regulation and tissue differentiation and organization. In view of this, the purpose of this study was to analyze the collagen, the major organic component of dental pulp ECM, in papillae of human tooth germs in different developmental phases. The maxillas and mandibles of 9 human fetuses ranging from 10 to 22 weeks of intr...

Analysis of Developing Tooth Germ Innervation Using Microfluidic Co-culture Devices.

Innervation plays a key role in the development, homeostasis and regeneration of organs and tissues. However, the mechanisms underlying these phenomena are not well understood yet. In particular, the role of innervation in tooth development and regeneration is neglected. Several in vivo studies have provided important information about the patterns of innervation of dental tissues during develo...
