[Ultrastructural aspects of reconstitution of the basal membrane in associations of dental components cultured in vitro].
Separation of the enamel organ and pulp of mice tooth germs by trypsin removed the basal lamina. Within 18 hours in cultivated reassociations of enamel organ and pulp, a new lamina was deposited. When the epithelial component was cultivated alone, no basal lamina formed.
