Abstract: Disclosed are methods for distinguishing subpopulations of cells within a cell population and determining analyte expression in the subpopulations. Herein, subpopulations of cycling and non-cycling cells were identified in a cell population based on expression of a first analyte (e.g., Ki-67). Levels of a second analyte were determined in the cycling cells, exclusive of the non-cycling cells.

Abstract: The present invention relates to "activated" immature astrocytes and methods of utilizing the activated immature astrocytes to reduce secondary necrosis and scar formation in central nervous system tissue as well as to promote axon and/or blood vessel growth or regeneration. In specific embodiments of the invention, activated immature astrocytes are used in injectable form or on a polymer implant. The activated immature astrocytes and pharmaceutical compositions comprising same, may be used to treat disorders of the nervous system resulting from accidents or diseases which have in some way damaged the nerve tissue.
