Abstract

We investigated the behavior of pre-osteoblasts cultured on polystyrene and photopolymerized ethoxylated bisphenol-A dimethacrylate gradient patterns. Gradient patterns varying in height from several hundred to 0 nm were prepared using nanoimprinting technology and a temperature-controlled stage. These patterns consisted of a 200 or 400 nm line width and a 400 or 800 nm pitch. The pattern height varied in a continuous fashion from several hundred nanometers to a flat surface. The morphology of the cells on these patterns was studied, and cell alignment along the pattern and cell elongation as a function of pattern height were examined.
