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.

Abstract: Genes that are up- or down-regulated during differentiation provide important leverage by which to characterize and manipulate early-stage pluripotent stem cells. Over 35,000 unique transcripts have been amplified and sequenced from undifferentiated human embryonic stem cells, and three types of differentiated progeny. Statistical analysis of the assembled transcripts identified genes that alter expression levels as differentiation proceeds. The expression profile provides a marker system that has been used to identify particular culture components for maintaining the undifferentiated phenotype. The gene products can also be used to promote differentiation; to assess other relatively undifferentiated cells (such as cancer cells); to control gene expression; or to separate cells having desirable characteristics. Manipulation of particular genes can be used to forestall or focus the differentiation process, en route to producing a specialized homogenous cell population suitable for human therapy.

Abstract: This disclosure provides a system for qualifying embryonic stem cells intended for human therapy. A large-scale sequencing project has identified important markers that are characteristic of undifferentiated pluripotent cells. Combinations of these markers can be used to validate the self-renewing capacity of ES cells, and their ability to differentiate into tissue types suitable for regenerative medicine. The marker system of this invention has been used to screen feeder cells, media additives, and culture conditions that promote proliferation of stem cells without differentiation. A culture system optimized by following these markers is suitable for rapid expansion of undifferentiated cells from existing lines, or the derivation of new lines that are equally apposite for clinical use.

Abstract: This disclosure provides a system for qualifying embryonic stem cells intended for human therapy. A comprehensive sequencing project has identified important markers that are characteristic of undifferentiated pluripotent cells. Combinations of these markers have been used to screen feeder cells, media additives, and culture conditions that promote rapid expansion of stem cells without differentiation. By measuring undifferentiated stem cell markers, and markers formed by early progenitors such as stromal cells, the user can quantitate the proportion and extent of differentiation. This establishes standardized criteria for master cell banks and cell cultures that can then be used to produce therapeutic cell populations and medicaments for use in regenerative medicine.
