Figure 5From: Evaluation of cytotoxic, genotoxic and inflammatory responses of nanoparticles from photocopiers in three human cell lines Levels of various cytokines at 6 and 24 h after nanoparticle treatment in THP-1 cell line. The concentrations of various cytokines measured in cell culture supernatant after nanoparticle treatment at different time points. All values are in picograms and are represented as mean± SE.Back to article page
