Deformation of the AL due to treatment with buffer or TrypLE (n = 8 per group). Fig. 4. shows representative results from DVC. Radial and circumferential expansion defined by E_rr and E_θθ , respectively, calculated from DVC of image volumes taken at 10 mmHg before and after treatment. Expansion was averaged in the whole specimen, or regionally in the central and in the combined peripheral and rim regions (Peri + Rim). The radial expansion was negative (i.e., contraction) and significantly smaller (i.e., more contraction) due to TrypLE than buffer (p ≤ 0.007). P-values are from Mann-Whitney U tests comparing the buffer and TrypLE groups, p<0.05 is significant. Values are mean ± std.
