Regulating Myoblast Phenotype Through Controlled Gel Stiffness and Degradation [PDF]
Tissue Engineering, 2007 Mechanical stiffness and degradability are important material parameters in tissue engineering. The aim of this study was to address the hypothesis that these variables regulate the function of myoblasts cultured in 2-D and 3-D microenvironments. Development of cell-interactive alginate gels with tunable degradation rates and mechanical stiffness was ...
