Prospective Identification, Isolation, and Profiling of a Telomerase-Expressing Subpopulation of Human Neural Stem Cells, using sox2 Enhancer-Directed Fluorescence-Activated Cell Sorting

ABSTRACT: Sox2 is expressed by neural stem and progenitor cells, and a sox2 enhancer identifies these cells in the forebrains of both fetal and adult transgenic mouse reporters. We found that an adenovirus encoding EGFP placed under the regulatory control of a 0.4 kb sox2 core enhancer selectively identified multipotential and self-renewing neural progenitor cells in dissociates of human fetal forebrain. Gene expression analysis of E/sox2:EGFP-sorted neural progenitor cells, normalized to the unsorted forebrain dissociates from which they derived, revealed marked overexpression of genes within the notch and wnt pathways, and identified multiple elements of each pathway that appear selective to human neural progenitors. We used adenoviral E/sox2:EGFP to transduce dissociates of the second trimester human ventricular zone (VZ)/ subventricular zone (SVZ), followed by EGFP-directed fluorescence-activated cell sorting (FACS). The sox2 isolates and unsorted controls from different gestational ages (16-19 wks, n=4) were then subject to RNA extraction and hybridization on Affymetrix microarrays.
