In natural tissues, the cells are arranged in a three-dimensional (3D) matrix which provides the appropriate functional, nutritional and spatial conditions. In scaffold guided tissue engineering 3D scaffolds provide the critical function of acting as extracellular matrices onto which cells can attach, grow, and form new tissue. The main focus of this paper is to understand cell behavior on micro-grooved and ridged substrates and to study the effects of geometrical constraints on cell motility and cell function. In this study, we found that BAE (Bovine Aortic Endothelial) cells naturally align with and are guided along 3D ridges and grooves machined into polymethylmethacrylate (PMMA) substrates. Average cell speed on micro-grooves and ridges ranged from 0.015 μm/s (for 12 μm wide and 10 μm deep ridges) to 0.025 μm/s (for 20 μm wide and 10 μm deep ridges). This compares with the cell motility rate on a flat PMMA surface where the average cell speed is around 0.012 μm/s. In this work we used scaffolds which were directly written with a focused proton beam, typically 1 MeV protons with a beam spot size of 1 × 1 μm 2. © 2005 Elsevier B.V.
