Therefore, it may be inferred that cumulus cells show some specificity in their interactions with collagens. Mixed collagens strongly attract cumulus cells as seen by their immediate attachment to the substrate. On mixed collagens, cells attached rapidly, appearing to be predominantly non-motile. The cuticle is a multilayered structure that consists primarily of collagens. On mixed collagens, the cells were spread very thinly on the substrate. Dog collagens were not commercially available and therefore not analysed in this study. The protein was described as possessing the highly conserved structural domains of all vertebrate and invertebrate collagens. Another example of an induced model is collagen-induced arthritis, which has been used to study rheumatoid arthritis. When the skin biopsy was performed, patients were not receiving any treatment known to influence collagen synthesis or deposition. All of the collagen-immunized mice had swollen and red paws and ankle joints within 3 days after lipopolysaccharide injection. A limitation (and obvious next step) to this study is that we do not have independent information about the integrity of the collagen matrix. Additionally, the monolayer on mixed collagens formed rapidly. They are highly ordered c o m p o s i t e materials consisting of collagens, proteoglycans and various glycoproteins, many of which have been poorly characterised.
