Abstract:
Disclosed are (1) osteogenic devices comprising a matrix containing substantially pure natural-sourced mammalian osteogenic protein; (2) DNA and amino acid sequences for novel polypeptide chains useful as subunits of dimeric osteogenic proteins; (3) vectors carrying sequences encoding these novel polypeptide chains and host cells transfected with these vectors; (4) methods of producing these polypeptide chains using recombinant DNA technology; (5) antibodies specific for these novel polypeptide chains; (6) osteogenic devices comprising these recombinantly produced proteins in association with an appropriate carrier matrix; and (7) methods of using the osteogenic devices to mimic the natural course of endochondral bone formation in mammals.
Abstract:
Disclosed is a method for the isolation and purification of polypeptides expressed in host cells by recombinant DNA techniques. A fused polypeptide is produced containing a desired polypeptide fused to additional amino acids. The additional amino acids define a leader sequence having properties exploitable in purification, a hinge region, and a cleavage site. The hinge region is cysteine-free and has a secondary structure which serves to expose the cleavage site to a selected endopeptidase. The method of the invention involves the production of a fused polypeptide which may be efficiently isolated by exploiting the properties of the leader sequence, and then efficiently cleaved at the cleavage site in an appropriate aqueous environment by virtue of the influence of the hinge on the cleavage agent/cleavage site reaction and other properties of the fused polypeptide.
Abstract:
The present invention is directed to methods and compositions for alleviating tissue destructive effects associated with the inflammatory response to tissue injury in a mammal. The methods and compositions include administering a therapeutically effective concentration of a morphogen or morphogen-stimulating agent sufficient to alleviate immune cell-mediated tissue destruction.

Abstract:
Disclosed are methods of utilizing a morphogenically active fragment of 60A protein to induce tissue morphogenesis, including methods for increasing a progenitor cell population in a mammal, methods for stimulating progenitor cells to differentiate and maintain their differentiated phenotype in vivo or in vitro, methods for inducing tissue-specific growth in vivo and methods for the replacement of diseased or damaged tissue in vivo.
Abstract:
Disclosed is DNA encoding a single-chain Fv (sFv) polypeptide defining a binding site which exhibits the immunological binding properties of an immunoglobulin molecule which binds c-erbB-2 or a c-erbB-2-related tumor antigen, the sFv includes at least two polypeptide domains connected by a polypeptide linker spanning the distance between the C-terminus of one domain and the N-terminus of the other, the amino acid sequence of each of the polypeptide domains includes a set of complementarity determining regions (CDRs) interposed between a set of framework regions (FRs), the CDRs conferring immunological binding to the c-erbB-2 or c-erbB-2-related tumor antigen.
