[Passage of labelled elements between two palatal shelves in vitro].
3H Fucose of 14C Galactosamine have been incorporated in vitro into a palatal shelf. This shelf has been associated with the homologous non-labeled palatal shelf on a normal medium. The mesenchyme of the explants which were incubated with the isotope is densely labeled. In the epithelium the cells are scarcely labeled. The isotope is dense in enlarged intercellular spaces. On the free surface, the tracer is located in front of those intercellular spaces and does not form a continuous coat. When the shelves have fused, the isotope migrates through the intercellular spaces of the non-labeled epithelium into the mesenchyme.
