Figure 2From: Multi-walled carbon nanotubes induce human microvascular endothelial cellular effects in an alveolar-capillary co-culture with small airway epithelial cells TEM of SAEC and HMVEC following addition of MWCNT to the apical Transwell chamber. SAEC and HMEC were grown in co-culture, followed by exposure of SAEC to DM or 1.2 μg/ml MWCNT for 6 or 24 h. Cells were washed thoroughly and collected for TEM. MWCNT were found within SAEC (arrows) but not in HMVEC from the basolateraly Transwell chamber.Back to article page
