    摘要: 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.

    摘要: 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.
