Images showing the results obtained when cells were cultured on the smooth surface.

<p>(<b>A</b>) smooth surface at SEM (Calibration Bar = 10 µm); (<b>B</b>) cells, cultured on a smooth surface, under SEM, show an elongated shape (Calibration Bar = 10 µm); (<b>C</b>) confocal image showing the relationship between cells and the smooth surface (Calibration Bar = 10 µm); (<b>D</b>) image showing the relationship between cells and the different surface texturing: (1) concave and (2) smooth.
