Fig. 3

Representative immunohistochemical images of the expression of OPN, TNC and E-selectin in different tissues. (a), (b) and (c) respectively represented TNC, OPN and E-selectin were expressed in different tissues and organs. In the pictures, (a) to (o) represented: (a) normal cerebral vessels; (b) cerebral vessels on day 5 post-SAH; (c) brain tissue; (d) thoracic aorta; (e) abdominal aorta; (f) heart; (g) liver; (h) lungs; (i) kidney; (j) spinal cord; (k) spleen; (l) pancreas; (m) retina; (n) mesenteric artery and (o) pulmonary artery. It showed that TNC had a wealth of expression in thoracic aorta and abdominal aorta, however, low level of expression in spastic cerebral vessels. OPN in brain tissue, spinal cord, kidney, pancreas, mesenteric artery and retina had obviously positive expression, this change also happened in spastic cerebral vessels after SAH. E-selectin and OPN had a similar region of expression, but the difference was that E-selectin had a higher expression in spleen. scale bars = 20 μm
