Abstract：
:The extracellular matrix of articular cartilage consists mainly of type II collagen and large aggregating proteoglycan (aggrecan). During arthritis and other joint diseases, the proteoglycan (PG) level of cartilage matrix is diminished, leading to impairment of normal joint function. A new method is described for measuring the changes in PG content of murine articular cartilage. The method is based on the automated densitometric analysis of patellar cartilage of standard, safranin O-stained sections of whole murine knee joints. It appeared to be possible to measure optical density in parallel layers of articular cartilage with high reproducibility. Approximately 25 sections can be evaluated within 1 h. Measuring a single section 10 times resulted in a coefficient of variation (CV) of 0.1-1.4%. A mean CV of 5-14% was calculated when a group of 18 sections was analyzed in quintuplicate. To validate the procedure, changes in PG content induced by arthritis or by intra-articular injection of TGFbeta-1 were analyzed by the image analysis method, the dimethylmethylene blue (DMB) assay and by visual grading. Although not a quantitive method, the newly developed image analysis method appeared to be more sensitive in detecting significant change in PG content of murine articular cartilage than the DMB method or visual grading. The image analysis method makes it possible to measure changes in PG content of specific areas of articular cartilage with higher sensitivity than the DMB method and eliminating the bias inherent to visual grading by human observers.
