Fig. 1 Photomicrographs of representative cross-sections of uninjured and balloon injured aortas from WKY and SHR. A: uninjured WKY; B: uninjured SHR; C and E: injured WKY; D and F: injured SHR. Note the smaller neointimal formation in the SHR aorta. A, B, C and D, hematoxylin and eosin, ×25. E and F, immunohistochemistry labeled for smooth muscle α-actin, ×250. Adv, adventitia; M, media; NI, neointima. Pathophysiology 2001 7, DOI: ( /S (00) )

Fig. 2 Photomicrographs showing representative cross-sections of uninjured and balloon injured carotid arteries from WKY and SHR. A: uninjured WKY; B: uninjured SHR; C and E: injured WKY; D and F: injured SHR. Note the exaggerated fibroproliferative response of injured SHR carotid artery. A and B, hematoxylin and eosin, ×40. C, D, E and F, immunohistochemistry labeled for smooth muscle α-actin C and D×40, E and F×320. Adv: adventitia; M: media; NI: neointima. Pathophysiology 2001 7, DOI: ( /S (00) )

Fig. 3 Bar graph showing the inverse relationship between neointima formation and VSMC resting membrane potentials of aorta and carotid arteries from SHR and WKY rats. Neo/Media was determined 14 days after balloon injury. Resting membrane potentials were measured by intracellular recording of VSMC from non-injured arleries. *P<0.05 vs. WKY. †P<0.05 vs. aorta.
