High-Resolution Strain Measurement for Biomechanical Parameters Assessment in Native and Decellularized Porcine Vessels

Figure 11

Characterization of porcine carotid arterial tissue before and after decellularization. (a,b) Macroscopic images of decellularized left common porcine carotid artery (artery length ∼ 50 mm; inner diameter ∼ 4 mm). Histology of porcine arteries: (c, e) native arteries and (d, f) decellularized arteries. (c) H&E staining of native arteries. (d) H&E staining of decellularized arteries showing complete removal of vascular cells. (e) Masson’s Trichrome staining of native arteries. (f) Masson’s Trichrome staining of decellularized artery showing collagens fibers and no cells (20x magnification). SEM micrographs of the luminal surface: (g) native arteries and (h) decellularized arteries; scale bar indicates 20 μm and 50 μm, respectively.
