A cartrilage and bone morphogenetic repairing composition comprising a collagen-free
aqueous solution of a polyoxyethylene-polyoxypropylene and an effective amount
of a bone morphogenetic protein, the molecular weight of polyoxypropylene as a
constituent of said polyoxyethylene-polyoxypropylene molecular is 900 to 4,000
in a unit of Dalton (D) and the ethylene oxide content is 5 to 90% by weight of
the polyoxyethylene-propoxypropylene molecule whereby the solution is liquid at
1 to 30 C. and gelatinizes at about 37 C. and a method of using the same.
