Extended Data Fig. 3: Swelling after 24 h exposure of ECM samples to HYPO and ISO solutions compared with samples in FRESH condition.

Measurements were carried out in parallel with MRI and mechanical characterization. Quantification revealed water uptake of 18 ± 3.6% in HYPO and 31 ± 5.0% in ISO conditions after 24 h. P values were determined using two-tailed t-tests for n = 8 biological samples. Box plot information: box limits show 25th and 75th percentiles, box middle lines show medians, and whiskers show minimum and maximum values.
