Figure 2: Mechanical response of fibers from young animals. Raw data (a, c, e) and regression coefficients (b, d, f) for (a-b) Cauchy stress-fiber strain (quadratic regression); (c-d) LaGrangian stress-fiber strain (linear regression); (e-f) radial strain-fiber strain (exponential regression) for fibers from 3-month-old wild-type (blue), desmin-null (red), and K19-null (orange) animals ( 𝑛 = 5 fibers/genotype). Different symbols within a color group represent data from individual experiments. Displayed regression lines in (a), (c), and (e) represent averaged coefficients for individual experiments reported in (b), (d), and (f). * indicates significant difference from wild-type. 𝑃 values are reported in the text.
