Matrigel® induces 3T3-L1 cell aggregation in a thickness-dependent manner. Phase-contrast images of 3T3-L1 cells seeded at a density of 30,000 cells/cm2 on polystyrene (A, B, C) and on Matrigel® (D, E, F). Images were taken of the 3T3-L1 cells upon plating, 24 hours post-plating, and 48 hours post-plating. Each image was taken at 20x magnification and is representative of three biological replicates (n = 3)
