Collagen and elastin microstructure of the porcine carotid artery. Selected two-photon z-series images through the porcine carotid intima, starting from the luminal surface (11.80 mm) through to the first lamellar unit. Elastin auto-fluorescence is in red and the collagen SHG is in green. A wavy sheet of elastin with circular holes throughout envelops the luminal surface of the artery. Individual, bunched-up collagen fibrils are radially arranged within the inner folds of the elastin lamellae. Scale bar, 50 μm.
