More than 300 primary cilia have been identified electronmicroscopically in a variety of embryonic and mature connective tissue cells. To further define the enigmatic function of these cilia, we examined the interrelationships between the basal apparatus and cytoplasmic organelles and the ciliary shaft and the extracellular matrix. The basal diplosome was(More)
The primary cilium is a ubiquitous cytoplasmic organelle of unknown function. Ultrastructural evidence of primary cilia in chondrocytes, and their colocalisation with the Golgi apparatus, has led to speculation that these structures are functionally linked. To investigate the relationship between these organelles, we examined the molecular anatomy of the(More)
Osteoarthritis is a chronic degenerative disease that affects the articular cartilage. Recent studies have demonstrated that lithium chloride exhibits significant efficacy as a chondroprotective agent, blocking cartilage degradation in response to inflammatory cytokines. However, conflicting literature suggests lithium may affect the physicochemical(More)
The metabolism and distribution of newly synthesized aggrecan present in the extracellular matrix of intact explant cultures of mature articular cartilage was investigated with respect to type VI collagen-stained chondrons. Using biochemical, autoradiographical and novel confocal immunohistochemical techniques it was shown that aggrecan exists as a number(More)
In several cell types fluid-flow deflection of primary cilia initiates a mechanotransduction pathway via polycystin 1 and 2 (PC1/2). In articular cartilage the chondrocyte primary cilium extends into cartilage matrix. Mechanical signals including compression and fluid flow trigger mechanosensitive regulation of matrix synthesis underpinning tissue(More)
