Co-culture of SAEC and HMVEC. Human small airway epithelial cells were cultured on the apical side of polyester Transwell inserts (0.4 μm pore size), while human microvascular endothelial cells were cultured in the basolateral chamber of the Transwell. Epithelial cells were exposed through the apical well to MWCNT in DM for various timepoints, and the effects to the underlying endothelium were assayed.
