Maintenance of architecture after intact porcine lung 7 hour decellularization. Scanning electron micrographs show intact tissues in normal lungs (A and C, 10,000× magnification) and topographic variance in the decellularized lung (B and D, 10,000× magnification). Panels (B) and (D) indicate no visible cells, but the matrix and collagen fibrils are maintained in the decellularized lung.
