Label-Free Segmentation of Co-cultured Cells on a Nanotopographical Gradient

http://pubs.acs.org/doi/full/10.1021/nl304097p

The behavior of different cell types co-cultured on nanopillar arrays is described.  The authors find that co-cultured cells can be differentiated based on the different pillar sizes.  For example, they suggest that 75 nm tall pillars will maximize the ratio of endothelial cells to fibroblast cells in a co-culture.
