چکیده

Link proteins are glycoproteins in cartilage that are involved in the stabilization of aggregates of proteoglycans and hyaluronic acid. We have identified link proteins in synovial cell cultures form normal canine synovium using sodium dodecyl sulfate-polyacrylamide gel electrophoresis, immunofluorescence, and immunolocation with specific antibodies by electrophoretic transfer. We have also found evidence for the synthesis of link proteins in these cultures by fluorography of radiolabeled synovial cell extracts. We have identified a 70,000 mol-wt protein in canine synovial cell culture extracts that has antigenic cross-reactivity with the 48,000-mol-wt link protein. Three link proteins were identified in normal canine articular cartilage. These results indicate that link proteins are more widely distributed in connective tissues than previously recognized and may have biological functions other than aggregate stabilization.

Bone Alkaline Phosphatase in Synovial Fluid Is Correlated to Radiographic Osteophyticchanges in a Canine Cranial Cruciate Transection Model of Osteoarthritis

INTRODUCTION: Osteoarthritis (OA) is considered to be a complex disease process that involves all components of the joint environment: cartilage, synovium, and subchondral bone. When there is joint injury, such as cranial cruciate ligament (CCL) rupture in dogs or humans, there are abnormal biomechanical stresses placed on the entire joint. Invariably, this leads to loss of the articular cartil...

Costal Versus Articular Chondrocytes in Alginate Three-Dimensional Cultures

Given the difficulties in accessing articular cartilage as a source of chondrocytes to be used in fabricating cartilage constructs, alternative sources are required. The present study examined chondrocytes from costal cartilage for their suitability in cartilage tissue engineering. Chondrocytes isolated from rat knee and rib hyaline cartilage were separately mixed with alginate and placed in a ...
