Segregation Versus Colocalization: Orthogonally Functionalized Binary Micropatterned Substrates Regulate the Molecular Distribution in Focal Adhesions
Orthogonally functionalized binary micropatterned substrates are produced using a novel protocol. The use of adequate peptido-mimetics enables an unprecedented segregation of purified alpha v beta 3 and alpha 5 beta 1 integrins in adjacent microislands and evidences the preference of U2OS cells to colocalize such receptors. Moreover, this tendency can be altered by varying the geometry and composition of the micropatterns.
