Adhesion of various cell types on collagen and kassinin amyloid fibrils. A, phase-contrast images of PC12, NIH3T3, and L929 cells adhered on kassinin amyloid and collagen after 24 h of culture. Scale bars, 100 μm for both the top and bottom panels. B, spreading of PC12 cells, shown to be unchanged across the different conditions, whereas the other cell types spread more on kassinin substrates compared with collagen. *, statistical significance (p < 0.01).
