Heat map of cytokine levels in culture supernatants of human peripheral blood mononuclear cells (PBMCs) (n = 8) that were exposed to 0 μM (Cells), 500 μM (T500) or 1000 μM (T1000) of triethylene glycol dimethacrylate (TEGDMA). The cytokine levels in the culture supernatants were measured with a multiplexed bead-based cytokine immunoassay. The median value combined from the eight different individuals were calculated for each cytokine and the values were normalized and transformed using Hierarchical Clustering Explorer into color codes representing higher (black), intermediate (grey), and lower (white) expression of each cytokine.
