  • Derivatized peptide-conjugated (meth) acrylate cell culture surface and methods of making
    Patent number: 8603820
    Abstract: A synthetic cell culture surface, prepared from a mixture of at least three (meth)acrylate monomers where one of the monomers has an N-hydroxysuccinimide moiety is provided, which supports the growth of cells including undifferentiated human embryonic stem cells in defined media. Methods for preparing the cell culture surface is also provided.
    Type: Grant
    Filed: May 19, 2010
    Date of Patent: December 10, 2013
    Assignee: Corning Incorporated
    Inventors: Arthur W. Martin, Shawn M. O'Malley, Simon K. Shannon, Christopher B. Shogbon, Carl M. Truesdale, Yue Zhou
  • Swellable (meth)acrylate surfaces for culturing cells in chemically defined media
    Patent number: 8329469
    Abstract: Synthetic surfaces capable of supporting culture of undifferentiated human embryonic stem cells in a chemically defined medium include a swellable (meth)acrylate layer and a peptide conjugated to the swellable (meth)acrylate layer. The swellable (meth)acrylate layer may be formed by polymerizing monomers in a composition that includes hydroxyethyl methacrylate, 2-carboxyehylacrylate, and tetra(ethylene glycol) dimethacrylate. The conjugated peptide may include an amino acid sequence of XaanProGlnValThrArgGlyAspValPheThrMetPro, where n is an integer from 0 to 3 and where Xaa is any amino acid. Further, disclosed herein is a swellable (meth)acrylate synthetic surface which can be sterilized by gamma irradiation.

  • Cell culture article and screening
    Patent number: 8168433
    Abstract: A method for producing a cell culture article having a synthetic polymer layer for incubating with cells includes diluting one or more (meth)acrylate monomers in a solvent and dispersing the diluted monomers on a surface of the cell culture article. Some or substantially all of the solvent is removed and the monomers are then polymerized on the surface of the article to form the synthetic polymer layer attached to the surface of the article.

  • (METH)ACRYLATE SURFACES FOR CELL CULTURE, METHODS OF MAKING AND USING THE SURFACES
    Publication number: 20090191634
    Abstract: A synthetic cell culture surface, prepared from a polymerized blend of at least two (meth)acrylate monomers is provided, which supports the growth of undifferentiated human embryonic stem cells in defined media augmented with fetal bovine serum. The cell culture surface forms a uniform layer over the growth area of a typical cell culture vessel.
