    摘要: The present invention is directed to isolated nucleic acid molecules that encode LIM mineralization protein, or LMP. The invention further provides vectors comprising splice variants of nucleotide sequences that encode LMP, as well as host cells comprising those vectors. Moreover, the present invention relates to methods of inducing bone formation by transfecting osteogenic precursor cells with an isolated nucleic acid molecule comprising a nucleotide sequence encoding splice variants of LIM mineralization protein. The transfection may occur ex vivo or in vivo by direct injection of virus or naked plasmid DNA. In a particular embodiment, the invention provides a method of fusing a spine by transfecting osteogenic precursor cells with an isolated nucleic acid molecule having a nucleotide sequence encoding LIM mineralization protein, admixing the transfected osteogenic precursor cells with a matrix and contacting the matrix with the spine. Finally, the invention relates to methods for inducing systemic bone formation by stable transfection of host cells with the vectors of the invention.

    摘要: A carrier matrix may be delivered to a target position within a patient in a minimally invasive manner by first cutting a collagen sponge sheet into a plurality of relatively small pieces. These pieces are sized so that, when wet, they are capable of flowing through a cannula and/or reduced-diameter syringe tip. The pieces are placed into a syringe and wetted, say with a morphogenic solution, and optionally mixed with a bulking material, which is similarly sized to fit through the cannula. The thoroughly mixed and wetted product forms a viscous aggregate which may then be injected into the patient at the target site.
