Three dimensional nanofibrillar surfaces induce activation of Rac.


Studies to define the mechanisms by which the extracellular matrix (ECM) activates Rho GTPases within the cell have generally focused on the chemistry of the macromolecules comprising the ECM. Considerably less information is available to assess the role of the physical structure of the ECM, particularly its three dimensional (3D) geometry. In this report… (More)
