Effects of Multiwalled Carbon Nanotube Reinforced Collagen Scaffolds on the Osteogenic Differentiation of Mesenchymal Stem Cells

Figure 7

Measurements of elastic modulus in the collagen scaffolds with different MWCNT concentrations. Compressive testing is performed on the MWCNT-collagen scaffolds located on a 24-well plate. Young modulus is determined from the elastic regime slope of stress-strain curves (<40% strain). * denotes a significant difference in elastic modulus from the collagen only group.
