Abstract: The invention provides cell-adherent polymeric coatings for articles, the coating including a synthetic, non-biodegradable polymer having a plurality of pendent amine groups, wherein the polymer is covalently immobilized on the article via latent reactive groups. The invention also provides methods for the long-term attachment of cells using the polymeric coatings.

Abstract: Inventive concepts relate generally to the field of cell culture, and more particularly to formation of three-dimensional aggregate(s) of eukaryotic cells. Cell culture vessels including a conical device having an inner surface being hydrophobic; and a frustum defining an open viewing aperture and a narrow end of the conical device are described. Ceil culture vessel arrays, assemblies and kits are described, as well as methods of making and using the devices.

Abstract: A stimuli responsive nanofiber that includes a stimuli responsive polymer, such as a thermally responsive polymer, and a cross-linking agent having at least two latent reactive activatable groups. The nanofiber may also include a biologically active material or a functional polymer. The stimuli responsive nanofiber can be used to modify the surface of a substrate. When the nanofiber includes a thermally responsive polymer, the physical properties of the surface can be controlled by controlling the temperature of the system, thus controlling the ability of the surface to bind to a biologically active material of interest.

Abstract: The invention provides cell-adherent polymeric coatings for articles having a nanofibrillar structure. The coatings include a synthetic, non-biodegradable polymer having at least one pendent amine group, wherein the polymer is covalently immobilized on the article via latent reactive groups. The invention also provides methods for the long term culturing of cells using the polymer coated nanofibrillar structures. The polymer coated nanofibrillar structures of the invention have been found to be particularly useful for the growth and differentiation of cells, including neural precursors.

Abstract: Glial precursor cell populations from mammalian central nervous system and embryonic stem cells has been isolated. These A2B5+ E-NCAM? glial-restricted precursor (GRP) cells are capable of differentiating into oligodendrocytes, A2B5+ process-bearing astrocytes, and A2B5? fibroblast-like astrocytes, but not into neurons. GRP cells can be maintained by regeneration in culture. GRP cells differ from oligodendrocyte-type-2 astrocyte (0-2A) progenitor cells in growth factor requirements, morphology, and progeny. Methods of use of GRP cells are also disclosed.
