Fig. 4. Lentiviral transduction targets a heterogeneous cell population in cortex slice cultures. GFAP (red) and NeuN (blue) double staining on LV-Ub-M-GFP transduced organotypic cortex slice cultures of C57Bl/6 mice revealed mostly GFAP-labelled GFP-positive glia, but also GFP-positive neurons. Arrows indicate transduced neurons, positive for both GFP and Neu-N. Bar, 50 µm.
