Abstract: The present invention provides a method of producing purified neural stem cells, comprising harvesting fluid containing neural stem cells from cerebrospinal fluid surrounding the spinal cord of an individual, isolating the neural stem cells from the fluid, culturing the neural stem cells in a culture medium effective to induce proliferation of the neural stem cells and purifying the cultured neural stem cells. Also provided is a method of treating a patient afflicted with a neurological condition, in which the purified neural stem cells are administered autologously into the same individual or heterologously to a patient other than the individual. Administration of the purified neural stem cells results in the purified neural stem cells propagating in the site of the brain region afflicted with the neurological condition.

Abstract: Described are a novel cell type in the neural lineage, and method of producing the same based on the degree of neural commitment and growth factor responsiveness in vitro and the potential to give rise to neural and non-neural progeny in vivo. The novel vell type of neural lineage and cells derived therefrom have a number of applications including applications regarding tissue engineering, transplantation and gene therapy and drug discovery. Also described are suggested uses of the method and cell type including isolating genes that positively and negatively regulate the transition from an ES cell to a neural cell and generally for studying ES cell models of mammalian neural development.

Abstract: A neural colony forming cell (NCFC) assay is described. The assay allows one to distinguish neural stem cells from neural progenitor cells. In one embodiment, the present invention provides a method for identifying neural stem cells or neural progenitor cells comprising: (a) suspending neural cells in a semi-solid medium which supports the growth of neural cells; (b) plating the cells in the semi-solid medium at a density that allows for the production of colonies; (c) culturing the plated cells until size differences can be discerned between the colonies; and (d) estimating colony size wherein the larger colonies are likely produced by neural stem cells and wherein the small colonies are likely produced by neural progenitor cells In alternate embodiments, NSC can be distinguished from neural progenitor cells by determining the morphology or antigen expression of the colonies.
