The invention discloses a method for editing a swine BMP15 (bone morphogenetic protein 15) gene by using CRISPR/Cas9. The method comprises the steps as follows: designing two gRNAs on an exon 1 of theBMP15 of a target swine genome, and constructing pX458 and pX459 vectors respectively, so that the BMP15 gene loses functions due to accurate deletion of DNA fragments. Compared with single gRNA medicated editing, the method has the advantage that the BMP15 gene can lose functions more effectively due to accurate deletion of DNA fragments of the exon.

The present invention pertains to the use of BMP-2, which is overexpressed in most common cancers, as 1) a target for cancer treatment therapies and 2) a means to diagnose cancer. The therapeutic component of this invention involves administering to a patient a composition that inhibits bone morphogenetic-2 activity. Such inhibition may be accomplished by ligands or antibodies that bind to BMP-2 or BMP-2 receptors. It may also be achieved by preventing the processing of pro-BMP-2, or blocking transcription or replication of BMP-2 DNA or translation of BMP-2 mRNA. The diagnostic component of the invention involves measuring the BMP-2 level in biological samples from both a patient and a subject and comparing those levels. Elevated levels of BMP-2 in the patient compared to the non-cancerous subject indicate cancer.

A cyclized peptide designated BMP Binding Peptide (BBP) is a synthetic peptide that avidly binds rhBMP-2. BBP increases the over-all osteogenic activity of rgBMP-2, increases the rate at which rhBMP-2 induces bone formation, and BBP induces calcification alone. Compositions and substrates including BBP, and methods of using BBP are useful in therapeutic, diagnostic and clinical applications requiring calcification and osteogenesis.

Controlled release of biopharmaceutical growth factors from a hydroxyapatite coating on a bioresorbable interference screw used in cruciate ligament reconstruction surgery on a human. Biologically active scaffolds, such as interference bone screws used for ligament fixation, made by growing calcium phosphate-based hydroxyapatite coatings on bioresorbable poly(α-hydroxy ester) scaffolds that provide controlled mineral dissolution and controlled release of bone morphogenetic protein-2. The biologically active scaffold provides improved bioavailability of BMP-2 growth factor that in turn provides enhanced graft-bone healing in the tibial bone tunnel. The coating method uses surface hydrolysis and modified simulated body fluid incubation which does not require solvent or heat and is conducted at room temperature.
