Cover legend: A representative example of the multiphenotype progeny derived from in vitro clonal expansion of a single multipotential neural stem cell isolated from embryonic rat telencephalon. The cells were fluorescently labeled using lineage-selective markers including cholera toxin B subunit (green), anti-9-O-acetylated GD3 (orange), anti-vimentin (red), and anti-GFAP (pink), and the cell nuclei were counterstained using DAPI (blue). The progeny include vimentin⁺ neural stem cells and radial glia, GFAP⁺ astrocytes, cholera toxin⁺ neurons, and 9-O-acetylated GD3⁺ neuroglial neuronal progenitors.
