Abstract:
Animal models constitute an indispensable tool to investigate human pathology. Here we describe the procedure to induce permanent and transient cerebral ischemia in the mouse and the rat. The model of transient occlusion of the middle cerebral artery (MCA) is performed by the insertion of an occlusive filament until the origin of the MCA while the permanent occlusion described in the mice is performed by a distal electrocoagulation of the MCA. Those models allow evaluating the efficiency of therapeutic strategy of ischemia from tissular aspect to behavioral and cognitive impairment assessment. They were widely used in the literature to evaluate the efficiency of different drugs including the cytokines and especially erythropoietin (EPO) or its derivatives.
