Figure 7. Schematic model of the collagen VI assembly found in human trabecular sheets. N and C termini are depicted in blue and yellow, respectively, and the collagenous triple helices in red. A: Model for the double-banded aggregates arising from the alignment of the N- and C-globular domains of the collagen VI tetramers. The black rectangles highlight the position of the transverse bands as seen in the electron micrographs. B: Model for the assemblies presenting a single transverse band. The single band arises from a double band with extra material (in green) filling the spaces between globular domains.
