title: Expression of anionic sites at the dermoepibolic junction.
abstract: The emergence of anionic sites during basement membrane zone formation was studied using migrating epidermis in organ culture as a model system. Ultrastructural investigations using a strongly cationized probe revealed that the heparitinase-sensitive, anionic sites were formed synchronously with the newly built basal lamina after 7 days in culture.
