Calcium chloride and sodium hydrogen phosphate form precipitation zones in gelatin gel, gel supplemented with cartilaginous extract, articular cartilage slices, and in demineralized bone. The cartilaginous extract exerts a marked inhibitory effect on the crystal quantity and clustering. The pretreatment of cartilage slices with hyaluronidase increases the crystal frequency. The morphology of crystals formed in gelatin and in cartilage was similar but quite different from the precipitation pattern found in demineralized bone.
