Figure 4. Co-localization of GFP expression cells and cardiac intrinsic adrenergic neurons 10 days post transduction.

Immunohistochemistry was performed in atria transferred with a lentiviral vector Lenti.EF1α-eGFP. A, GFP expression. B, same tissue sample stained with sympathetic neuron marker anti-TH. C, overlay of GFP and anti-TH (Texas-red streptavitin). Scale bar, 50 μm for all the images.
