  • Patent number: 8530236
    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.

  • Patent number: 8354274
    Abstract: Synthetic surfaces capable of supporting culture of eukaryotic cells including stem cells and undifferentiated human embryonic stem cells in a chemically defined medium include a swellable (meth)acrylate layer and a polypeptide conjugated to the swellable (meth)acrylate layer. The swellable (meth)acrylate layer may be formed by polymerizing monomers in a composition that includes a carboxyl group-containing (meth)acrylate monomer, a cross-linking (di- or higher-functional) (meth)acrylate monomer, and a hydrophilic monomer capable of polymerizing with the carboxyl group-containing (meth)acrylate monomer and the cross-linking (meth)acrylate monomer. The swellable (meth)acrylate layer has an equilibrium water content in water of between about 5% and about 70%. The conjugated peptide may include an RGD amino acid sequence.

  • 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.

  • 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.
