A bone precursor composition comprising a cement mixture and a pore-forming agent is provided for bone implant. Preferably, the pore-forming agent has a particle size of 20-500 mu m. More preferably, the proportion of the pore-forming agent is 7-40% (w/w). The composition may further include a bioactive agent, preferably a bone morphogenic protein or nucleic acid encoding BMP encapsulated in the pore-forming agent. The moldability of the composition can be modulated by the addition of a binder. The invention provides a kit and implant device comprising the bone precursor composition. The invention also provides an implantable prosthetic device comprising a prosthetic implant having a surface region and a bone precursor material disposed on the surface region. The kit and devices may further comprise one or more additional components including a bioactive agent and a binder. Methods of inducing bone formation and delivering the bioactive agent are provided.
