Fig. 1From: Lymphocytes influence intracranial aneurysm formation and rupture: role of extracellular matrix remodeling and phenotypic modulation of vascular smooth muscle cellsRag1 knockout animals show less IA formation and rupture. Representative images of cerebral arteries at 14 days and quantification of IA formation and rupture. Scale bars = 2 mm. a No IA formation. b Unruptured IA. c Ruptured IA producing SAH. Rag1 group has significantly lower total IAs per animal (d) and ruptured IAs per animal (e). f Rag1 group has significantly lower rate of IA rupture. * p ≤ 0.05Back to article page
