Fig. 6From: A novel human 3D lung microtissue model for nanoparticle-induced cell-matrix alterationsCytokine protein expression in 3D microtissues exposed to test nanomaterials. Microtissue lysates were analyzed for expression of cytokines (IL-1β, IL-6, TNF-α) or the growth factor, HGF, following exposure to 10 μg/mL of carbon black, carbon nanotubes, or asbestos fibers for 4 days. Mean analyte contents per mg of total protein in the lysate were quantified using Luminex bead assays as described in Materials and Methods. The mean is based on duplicate experimentsBack to article page
