  • Patent number: 6605117
    Abstract: Disclosed is an osteogenic device capable of inducing the formation of endochondral bone in a shape conforming substantially to the shape of the device when implanted in a mammalian host. The device includes an osteogenic protein dispersed within a porous matrix comprising a polymer of collagen and glycosaminoglycan cross-linked to an MC value of about 800 to about 60,000. Also disclosed are a method of inducing mammalian bone growth, and a method of inducing conductive bone growth from viable mammalian bone.

  • Publication number: 20030104993
    Abstract: Disclosed are therapeutic treatment methods, compositions and devices for maintaining neural pathways in a mammal, including enhancing survival of neurons at risk of dying, inducing cellular repair of damaged neurons and neural pathways, and stimulating neurons to maintain their differentiated phenotype. In one embodiment, the invention provides means for stimulating CAM expression in neurons. The invention also provides means for evaluating the status of nerve tissue, including means for detecting and monitoring neuropathies in a mammal. The methods, devices and compositions include a morphogen or morphogen-stimulating agent provided to the mammal in a therapeutically effective concentration.

  • 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.
