the results showed that associated with the cells were ( a ) large proteoglycans , typical for cartilage , apparently bound to hyaluronic acid at the cell surface , ( b ) an intermediate-size proteoglycan with chondroitin sulphate side chains ( this proteoglycan , which had a large core protein , was only found associated with the cells and is apparently not related to the large proteoglycans ) , ( c ) a small proteoglycan with dermatan sulphate side chains with a low degree of epimerization , and ( d ) a somewhat smaller proteoglycan containing heparan sulphate side chains .
