Porosity of dECM scaffolds. The porosity of randomly oriented (RO, ROX) and aligned (AO, AOX) dECM scaffolds was analyzed dry and after swelling in PBS via confocal microscopy and image processing software (ImageJ). The porosity of dry (red bars) and swollen (blue bars) is presented as a percentage. Shared letters indicate no significant difference between groups (n ≥ 25, p < 0.05).
