Figure 2From: Quantification of particle-induced inflammatory stress response: a novel approach for toxicity testing of earth materialsROS upregulation, cell viability and ISR of A549 cells to glass beads. The cellular response to glass with increasing particle loading is presented with three different figures, all normalized to a control. (a) ROS upregulation, (b) cell viability, and (c) ISR - ROS upregulation divided by cell viability. For some data points, the error bars are hidden by the symbols.Back to article page
