Figure 4. Multiscale biomechanical response of WT, K14-COL5A1, and Col5a2pN/+ murine skin.
(a) Slope of OI variation upon stretching of skin samples from WT, K14-COL5A1, and Col5a2pN/+ mice; (b) Same with entropy; (c) Same with tangent modulus; (d) Same with heel region length; (e) Same with failure stretch ratio; (f) Same with ultimate tensile strength. Error bars corresponds to SEM. *(resp. **) indicates p < 0.05 (resp p < 0.01). Averaged values are calculated over all samples.
