Figure 5From: Differential regulation of intracellular factors mediating cell cycle, DNA repair and inflammation following exposure to silver nanoparticles in human cellsSilver nanoparticles induced cytokines and chemokines production in normal human lung fibroblasts (IMR90). The graphs indicate the production of cytokines and chemokines in pg/ml (mean ± SD) by normal human fibroblasts after incubating with 400 μg/mL of silver nanoparticles for a period of 48 hours. The cytokine levels were measured in untreated cells (Control) and in cells treated with silver nanoparticles (treated (Ag-np)). Statistical significance was determined between untreated and treated samples using Student's t test. *p value ≤ 0.05.Back to article page
