From: Self-agglomerated collagen patterns govern cell behaviour
Different topographical patterns formed after collagen droplet evaporation. (a) Schematic overview of the climate chamber and pipetted collagen droplets on glass samples, which form a collagen stain. (b) Polarized light microscopy (PLM) image accompanied by a sketch of the collagen patterns formed when using a 5 mg/ml collagen solution. Three different regions formed, i.e. an isotropic region in the center, a region with concentric collagen rings patterns in the middle and a radial v-shaped pattern at the periphery. For high magnification images of the patterns, see Fig. 6b1, c1 and d1.
