[Immunologic distribution of collagens during the embryogenesis of the secondary palate in the Fauve de Bourgogne rabbit].
The distribution of collagens during development of the palate in the Rabbit embryo is studied using the technique of indirect immunofluorescence. During the phase prior to epithelial contact, only types II and III are found in the mesenchyme. Type I, which is abundant on the free surface of apical epithelial cells, becomes even denser at the time when the palatine projections unite. Type IV fluorescence clearly outlines the basement membrane. When epithelial development regresses, fluorescence in type I and IV decreases in a way such that, in the areas where mesenchymal coalescence is apparent, no immunofluorescent labeling is observed.
