Collagen Scaffold Arrays for Combinatorial Screening of Biophysical and Biochemical Regulators of Cell Behavior

Authors


Abstract

image

Arrays of 3D macroporous collagen scaffolds with orthogonal gradations of structural and biomolecular cues are described. Gradient maker technology is applied to create linear biomolecular gradients within microstructurally distinct sections of a single CG scaffold array. The array set up is used to explore cell behaviors including proliferation and regulation of stem cell fate.
