Die Verteilung verschiedener Kollagentypen und des Laminins in der Gingiva von Marmoset-Affen (Callithrix Jacchus).

The distribution of the collagen types I, III, IV, V, VI and of the glycoprotein laminin have been examined in the healthy gingiva of the marmoset with the indirect immunofluorescence method. It has been shown that collagen type I formed thick fibrils in a wave-like pattern, while collagen type III formed thinner fibrils, especially under the epithelial basal membrane. Collagen type IV and laminin showed a strong fluorescence in the basal membrane (epithelium, vessels, nerves). Collagen type V has been demonstrated as a fine fibrillar pattern in the lamina propria and occasionally close to the basal membrane. Collagen type VI has been represented as a microfibrillar network in the connective tissue matrix with a brilliant pericellular fluorescence around vessels and nerves. The study showed the structural model of the connective tissue matrix of the marmoset gingiva and allows a later comparison between inflamed and healthy gingiva.
