Abstract: The invention features delayed-setting calcium phosphate pastes which are useful for the preparation of delivery vehicles for biologically active agents, useful for the treatment of orthopedic conditions and can be stored for long periods without prematurely setting.

Abstract: A method and composition are provided for treating cancer in a mammal.

Abstract: Osteogenic bone implant compositions that approximate the chemical composition of natural bone are provided. The organic component of these implant compositions is osteoinductive despite the presence of the inorganic component and, further, is present in an amount sufficient to maximize the regenerative capabilities of the implant without compromising its formability and mechanical strength. The composition may be an osteoinductive powder, including demineralized bone matrix (DBM) particles, a calcium phosphate powder, and, optionally, a biocompatible cohesiveness agent. The powder may be combined with a physiologically-acceptable fluid to produce a formable, osteoinductive paste that self-hardens to form a poorly crystalline apatitic (PCA) calcium phosphate having significant compressive strength. The bone implant materials retain their cohesiveness when introduced at an implant site and are remodeled into bone in vivo.

Abstract: Implants associated with bone are coated with natural bony tissue by incubating the implant with osteoblasts under conditions where the osteoblasts grow and lay down a bony coating. Different methods are provided for maintaining the osteoblasts in contact with the implant and allowing for the growth and maintenance of the osteoblasts with formation of the bony tissue. The resulting coated implants can provide for a better juncture with the natural tissue in the patient, so as to provide for a more comfortable and effective prosthesis or other device.
