Patents by Inventor Roeland Nusse

Roeland Nusse has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20040248803
    Abstract: Compositions of purified biologically active Wnt proteins are provided. Wnt proteins are found to be hydrophobic and post-translationally modified by addition of a lipid moiety at a conserved cysteine residue. Methods for isolation of Wnt utilize detergents that maintain the solubility of the modified protein.
    Type: Application
    Filed: April 1, 2004
    Publication date: December 9, 2004
    Inventors: Roeland Nusse, Karl H. Willert
  • Publication number: 20030040051
    Abstract: Wnt receptor compositions and methods of use are disclosed. In particular, methods using Wnt receptors, such as Dfz2, in screens for compounds which modulate the binding of a Wnt polypeptide to a Wnt receptor.
    Type: Application

  • Patent number: 6465249
    Abstract: Mammalian progenitor or stem cells are expanded in vitro by increasing the levels of &bgr;-catenin in the cell. The expanded cells substantially maintain their original phenotype including the ability to give rise to multiple types of differentiated cells. The intracellular levels of &bgr;-catenin may be manipulated by providing exogenous &bgr;-catenin protein to the cell, or by introduction into the cell of a genetic construct encoding &bgr;-catenin. The &bgr;-catenin may be a wild-type or stabilized mutant form of the protein. Preferably the long term cell culture medium substantially lacks stromal cells and cytokines.
    Type: Grant
