摘要:
The present invention is directed to novel non-woven fabrics containing growth and differentiation factor proteins. Said fabrics are specifically designed to accelerate tissue regeneration and wound healing processes of mammalian tissues. Furthermore, the invention provides wound dressings, pads or implants comprising the novel non-woven fabrics.
摘要:
This invention provides for a protein of the TGF-β superfamily in which the cysteine involved in the normal formation of homodimers is changed to another amino acid. These mutant proteins, as monomers, display higher bone morphogenetic activity than the wild-type protein dimers. Also provided is a method for producing and isolating these monomers by plasmid driven expression in various host systems including E. coli. In addition, the invention discloses the use of an agent containing purified monomers in preventing and treating diseases and problems affecting bone and/or cartilage.
摘要:
The invention provides DNA sequences encoding novel members of the TGF-β family of proteins. The TGF-β family comprises proteins which function as growth and/or differentiation factors and which are useful in medical applications. Accordingly, the invention also describes the isolation of the above-mentioned DNA sequences, the expression of the encoded proteins, the production of said proteins and pharmaceutical compositions containing said proteins.
摘要:
A cartrilage and bone morphogenetic repairing composition comprising a collagen-free aqueous solution of a polyoxyethylene-polyoxypropylene and an effective amount of a bone morphogenetic protein, the molecular weight of polyoxypropylene as a constituent of said polyoxyethylene-polyoxypropylene molecular is 900 to 4,000 in a unit of Dalton (D) and the ethylene oxide content is 5 to 90% by weight of the polyoxyethylene-propoxypropylene molecule whereby the solution is liquid at 1 to 30° C. and gelatinizes at about 37° C. and a method of using the same.
摘要:
The present invention is directed to GDF-5 related proteins having an improved capability of inducing cartilage formation and a reduced capability of inducing bone formation. The novel proteins are particularly useful in the treatment of cartilage defects, wherein the formation of bone tissue is undesirable.
摘要:
This invention relates to the production and use of pharmaceutical growth factor compositions with novel characteristics, e.g. improved solubility and controlled release characteristics under physiological conditions. The compositions of one or more precursor proteins of growth factors of the GDF family provoke morphogenic effects such as growth, differentiation, protection and regeneration of a variety of tissues and organs, e.g. bone, cartilage, tendons, ligaments, nerves and skin. The compositions can be advantageously used for the healing of tissue-destructive injuries and for the prevention or therapy of degenerative disorders.

摘要:
The application relates to novel biosynthetic growth factor mutants, derived from GDF-5, which exhibit improved biological activity. Mutations at positions 453 and 456 of human GDF-5 are disclosed, as well as use of these mutants in therapy of diseases associated with tissue degeneration/destruction.
摘要:
A process for the production of a purified recombinant GDF-5 related protein in prokaryotes comprises the steps of bacterial cell disruption and inclusion body solubilization to obtain a solubilized monomer of a GDF-5 related protein, said process characterized by a) disruption of bacterial cells with a high pressure homogenizer at a disruption pressure between 800 and 900 bar; and/or b) treatment of the recovered inclusion bodies with a denaturing solubilization buffer comprising L-arginine.
