Additional file 2 of Lymphatic vessels are present in human saccular intracranial aneurysms
Additional file 2: Fig. S1. Representative images of thrombus in the saccular intracranial aneurysm (sIA) presenting immunohistochemical staining for LYVE-1 (A), podoplanin (B), VEGFR-3 (C), and Prox1 (D). Ring-shaped structures of immunohistochemical staining positive for LYVE-1 (E) and podoplanin (F), i.e., lymphatic vessels, in the sIA thrombus. The negative controls are shown as insets. Black arrows point down towards the lumen. Scale bar: 50 μm. Positive staining is brown. Haematoxylin background staining.

Lymphatic vessels are present in human saccular intracranial aneurysms
AbstractSaccular intracranial aneurysm (sIA) rupture leads to subarachnoid haemorrhage and is preceded by chronic inflammation and atherosclerotic changes of the sIA wall. Increased lymphangiogenesis has been detected in atherosclerotic extracranial arteries and in abdominal aortic aneurysms, but the presence of lymphatic vessels in sIAs has remained unexplored. Here we studied the presence of lymphatic vessels in 36 intraoperatively resected sIAs (16 unruptured and 20 ruptured), using immunohistochemical and immunofluorescence stainings for lymphatic endothelial cell (LEC) markers. Of these LEC-markers, both extracellular and intracellular LYVE-1-, podoplanin-, VEGFR-3-, and Prox1-positive…
Serum Amyloid A Is Present in Human Saccular Intracranial Aneurysm Walls and Associates With Aneurysm Rupture
AbstractSaccular intracranial aneurysm (sIA) rupture leads to a disabling subarachnoid hemorrhage. Chronic inflammation and lipid accumulation in the sIA wall contribute to wall degenerative remodeling that precedes its rupture. A better understanding of the pathobiological process is essential for improved future treatment of patients carrying sIAs. Serum amyloid A (SAA) is an acute-phase protein produced in response to acute and chronic inflammation and tissue damage. Here, we studied the presence and the potential role of SAA in 36 intraoperatively resected sIAs (16 unruptured and 20 ruptured), that had previously been studied by histology and immunohistochemistry. SAA was present in all…
