Abstract

The fabrication of substrates containing arrays of cracks in which cell-adhesive proteins are selectively adsorbed was described. The widths of the cracks were similar in size to individual adhesion complexes and can be modulated by adjusting the mechanical strain applied to the substrate. It was observed that morphology of cells can be reversibly manipulated multiple times through in situ adjustment of crack widths and hence the amount of the cell-adhesive proteins accessible to the cell. The results show that these substrates provide a new tool for assessing cellular responses associated with exposure to matrix proteins.
