The preservation of articular cartilage.

Slivers of articular cartilage were stored in Ham's medium, plasma, polyvinyl pyrrolidone, and dimethyl sulphoxide at 0, -20, 4, and 38C. Survival was monitored by potassium determinations and autoradiography using S-35 and by matrix staining. Survival of 48 days was obtained in Ham's medium at 4C.
