Possible requirement of collagen gel substratum for production of mucin-like glycoproteins by primary rabbit tracheal epithelial cells in culture.
Primary rabbit tracheal epithelial cells growing on either plastic surface or collagen gel produce high molecular weight glycoconjugates. Biochemical characterization of these materials show they are exclusively hyaluronic acid when cells are grown on plastic surface, but a mixture of hyaluronic acid and mucin-like glycoproteins when grown on collagen gel. This research suggests that the substratum plays an important role in the maintenance or differentiation or both of mucous cells in culture.
