Figure 1: Atomic force microscopy (AFM) analysis of IEC-6 normal cell morphology with height scale (color bar): 2000 nm (a) and image of normal IEC-6 cell in 3D view (b). Effect of 1 h exposure with TcdA (100 ng/mL) on IEC-6 cell morphology with height scale (color bar): 4000 nm (c) and image of IEC-6 cell treated with TcdA (100 ng/mL) in 3D view (d). The images were obtained using AFM in contact mode (scan size μm2).
