Co-culture of spinal cord cells with differentiated human fetal brain neural stem cells. Spinal cord cells labelled with GFP-expressing lentivirus (green fluorescence, arrows) do not stain with GFAP, Map2ab, Olig2 and Nkx2.2 antibodies (red) in contrast to neural precursor cells (arrowheads). Scale bars = 10 μm.
