...us -- also occurs near the cell's surface where it regulates at least one and possibly many kinds of proteins, providing a novel target for the development of new drugs. The discovery, published in the 8 April 2005 issue of the journal Cell, answers a question dating back to the 1950s: How do cells control th...Gene therapy promising for growing tooth-supporting bone
...years. BMP-7 is part of a family of proteins that regulates cartilage and bone formation. Recent studies have shown that BMPs are present in tooth development and periodontal repair. This study mixed BMP-7 genes with an inactivated virus in a gel-like carrier and injected it into wounds.
