Figure 4From: Evaluation of cytotoxic, genotoxic and inflammatory responses of nanoparticles from photocopiers in three human cell lines Percent viability of cells determined using typan blue staining at different time points and treatment concentrations. Cell viability results depicted as a function of administered dose in three cell types (A) THP-1 cell line, (B) nasal epithelial cells and (C) small airway epithelial cells. All values are represented as mean ± SE.Back to article page
