From: Metallic nanoparticles reduce the migration of human fibroblasts in vitro
Production of ECM molecules by fibroblasts decreased on exposure to AgNPs. The human fibroblast cell line treated with AgNPs at concentrations of 0.1, 1, or 10 μg/mL for 24 h was analysed using indirect immunofluorescence to detect laminin and collagen-1 production. Photomicrographs in (a) show laminin (green; upper panels) and collagen-1 (green; lower panels) production in NP-treated cells. Magnification, 200×. Graphs in b and c show the fluorescence intensity for laminin and collagen-1, respectively. Data have been presented as mean ± SEM. CTR: non-treated cells; *p < 0.05, **p < 0.01, ***p < 0.001
