Controlling Growth and Osteogenic Differentiation of Osteoblasts on Microgrooved Polystyrene Surfaces - Fig 2

<p><b>Fluorescent images of DAPI/phalloidin-stained MG-63 cells (a-c) and SEM images (d–f) after 24-hour attachment on 2/6 (a, d), 4/11 (b, e) and flat control (c, f).</b> Both microgrooved surfaces induced alignment of the cells in the direction of the grooves. While cells on 2/6 were predominantly found on the ridges, bridging over two or more grooves, on 4/11, the cells were predominantly found inside the grooves. Cells on the flat control appeared randomly oriented and spread.
