【 摘 要 】

The effect of type IX on in vitro fibrillogenesis of type II collagen indicated that, while not preventing fibrillogenesis, the presence of type IX collagen reduced the size of the type II fibre aggregates. This observation is consistent with the in vivo localisation studies of type IX collagen. Using the immunogold labelling technique, type IX collagen was shown to be located evenly on small fibrils which occur at higher concentration closer to the cell. Therefore type IX collagen may function as a regulator of fibre diameter in articular cartilage.
