    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 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.
