Effects of Matrix Viscoelasticity on Cell-Matrix Interaction, Actin Cytoskeleton Organization, and Apoptosis of Osteosarcoma MG-63 Cells

Investigators prepared a viscoelastic hydrogel matrix with a storage modulus of about 2 kPa and a loss modulus adjustable from 0 to 600 Pa, through adding linear alginate and regulating the compactness of a polyacrylamide covalent network.
