Fig 4. Immunolocalization of ATB0,+ transporter in EpiAirway™.

Fig 4

Confocal laser scanning microscopy of EpiAirway™ layers immunolabelled for ATB0,+ transporter (green) is shown. Nuclei were stained with propidium iodide (red). Left: single XY scan acquired in correspondence of the apical membrane. Top: XZ section of the plane. Right: 3D reconstruction of z-stacks confocal images; about 30 horizontal sections were acquired. Representative images from three independent experiments are shown. Bar, 20 μm.
