  • Patent number: 6565843
    Abstract: The invention provides methods, compositions and devices for inducing tissue-specific regeneration in a mammal, or for stimulating proliferation of mammalian progenitor cells. The present methods, compositions and devices make use of osteogenic protein 1 (OP-1), which is appreciated herein as a tissue morphogen, i.e., a substance competent to induce tissue-specific morphogenesis of mammalian body tissues in addition to bone and/or cartilage. Alternatively, the present methods, compositions and devices make use of other naturally-occurring or biosynthetic proteins sharing a defined structural and functional relationship with OP-1 and thus appreciated herein also to function as tissue morphogens. Optionally, OP-1 or a related protein can be used alone or when adsorbed on a support matrix which provides an anchoring substratum for proliferation and/or differentiation of progenitor cells during tissue-specific morphogenesis.

The terminally sterilized devices of the invention are characterized in that they induce bone formation following implantation into a mammal. Also disclosed is a method for inducing bone formation in a mammal by implanting a terminally sterilized device of the invention into a preselected locus in a mammal. Also disclosed is a method for preparing the terminally sterilized device of the invention.

  • Publication number: 20020028453
    Abstract: The invention disclosed herein provides methods and compositions for the computer-assisted design of morphogen analogs. Practice of the invention is enabled by the use of at least a portion of the atomic co-ordinates defining the three-dimensional structure of human osteogenic protein-1 (hOP-1) as a starting point in the design of the morphogen analogs. In addition, the invention provides methods for producing morphogen analogs of interest, and methods for testing whether the resulting analogs mimic or agonize human OP-1-like biological activity. The invention also provides a family of morphogen analogs produced by such methods.
