Phototriggering of Cell Adhesion by Caged Cyclic RGD Peptides

Abstract

Restrained potential: A caged cyclic peptide attached to a surface is able to trigger cell attachment to the surface with spatiotemporal definition upon exposure to light (λ=351 nm). The peptide shows no integrin-binding activity in its caged form, but mediates cell adhesion effectively after irradiation (see optical microscopy image of cells on a surface irradiated through a mask in bands 100 μm in width).
