Quantitative studies of sulphate uptake by the cells of human cartilage (McElligott and Collins, 1960) have shown that chondrocyte activity increases in articular cartilage as age advances, while it decreases in costal cartilage. A considerably enhanced activity of articular over costal cartilage cells was recorded in cases where there was nakedeye evidence of destruction and fibrillation of the articular cartilage. We postulated a possible relationship between the increased sulphate utilization of ageing articular cartilage, the degree of osteo-arthritis, and the peculiar rearrangement and grouping of chondrocytes that are known to occur in these conditions. In order to investigate this, a large number of autoradiographs of cartilage incubated with labelled sulphate have been prepared and studied side by side with parallel sections stained by various methods including those that demonstrate mucopolysaccharides. It is the results of these studies that we now report.Material and Methods A patella was removed at each of 34 necropsies from persons ranging in age from 4 to 83 years. Specimens were processed as soon as possible after removal and in all cases within 2 hours. During this delay the specimens were stored at 40 C. in the incubation medium, a pro-cedure that reduces the rate of loss of chondrocyte activity. The intervals between death and autopsy and between the collection of the specimen and its processing were carefully noted.
