Arterial plaque formation after ADSC transplantation at early stage of AS. (A) (a). Long strip plaque (width, 0.12 cm; length, 0.62 cm) in carotid artery with thickened intima; (b). Plaque (width, 0.20 cm; length, 0.33 cm) at aortic arch; (c). Plaque (width, 0.11 cm; length, 0.28 cm) in the abdominal aorta; (d). Normal carotid artery wall; (e). Small plaque (width, 0.09 cm; length, 0.18 cm) in the middle of the abdominal aorta; (f). Normal abdominal aorta. (B) The incidence of atherosclerotic plaque in aortic arch, carotid artery, and abdominal aorta (incidence = number of animals with plaques/total number of animals in each group × 100%, n = 6 in each group).
