Complex stiffness gradient substrates for studying mechanotactic cell migration (adv. Mater. 45/2012).

Abstract:

Complex stiffness gradient substrates for the study of mechanotactic cell migration are developed by Easan Sivaniah, Kristian Franze, and co-workers on page 6059. Polyacrylamide gels are cast upon a stiff support with controlled topography, resulting in a thin gel layer of variable height. The topographical profiles project a stiffness map onto the gel, resulting in controlled linear and non-linear 2D stiffness gradients. Fibroblasts, which migrate towards stiffer substrates, accumulate in areas with a gel thickness below 15 μm.
