In situ and in vitro assembly of cuticle collagens from marine worms.
The in situ assembly of cuticular collagens is compared in a deep sea hydrothermal vent worm, the vestimenferan Riftia pachyptila, and a shallow sea water annelid, Arenicola marina. The in vitro assembly of their extracted collagen is compared following different methods of fixation. We show that the cuticle organization of the shallow sea water species A. marina is very similar to that of both these species. These the Matsumura method, we compare the cuticle collagen amino acid composition of both these species. These results lead us to discuss the similarity of these collagens with that of other results lead us to discuss the similarity of these collagens with that of other invertebrates and vertebrates.
