Samir Singh showed scaffold modulus and peptide functionalization affected tumor cell migration in a 3D synthetic matrix. His paper, entitled "A peptide functionalized poly(ethylene glycol) (PEG) hydrogel for investigating the influence of biochemical and biophysical matrix properties on tumor cell migration" appears in Biomaterials Science.
