Figure 1From: Influenza H5N1 virus infection of polarized human alveolar epithelial cells and lung microvascular endothelial cells Representation of the transwell insert-setup during the influenza virus infection experiment. Type I-like alveolar epithelial cells or HLMVEs (indicated in blue) were seeded on top of the porous membrane. During apical infection (A) virus was added into the apical compartment while the transwell was placed upside down during basolateral infection (B).Back to article page
