Fig. 4. Mechanical characterization of the scaffold sets. Its features are the ideal ones for generating skeletal muscle tissue. (a) The conical coaxial adjustment of the EpsiMu transmission line. (b) Conductivity (S m−1) of the cryogels. (c) Swelling ratio of each cryogel. (d) Compression axis from the stiffness assay of the cryogel. Vertical arrows are the parallel condition and horizontal arrows are the perpendicular condition. (e) Stiffness results for cryogels in both directions. (b, c and e) CNTs(−) in light grey and CNTs(+) in dark grey. All results are mean ± SEM. *p-value = 0.05.
