Figure 1.
Schematic to illustrate the range of molecular interactions in cartilage to matrix (from Heinegard 2009). Amongst interactions shown are territorial and interterritorial networks of type II/XI collagen fibres and type VI collagen networks; aggrecan aggregates with hyaluronan and link protein; possible retention of aggrecan G3 domain in territorial, but not interterritorial matrix and interaction of G3 with fibulins and tenascin.
