A bone morphogenetic protein (BMP) fraction obtained from the organic matrix of dentin is extractable from human osteosarcoma. A fresh en-bloc specimen excised from the femur of a 16-year-old boy was extracted with 4 M guanidine hydrochloride. The GuHCl-soluble, water-insoluble protein fraction induced new bone formation when implanted into the thigh muscles of athymic nude mice.
