[Effects of electroacupuncture on endothelial progenitor cells in peripheral blood and bone marrow in local cerebral ischemia/reperfusion rats].

Objective: To observe the influence of electroacupuncture (EA) of "Hegu" (LI 4) on blood stromal cell-derived factor 1alpha (SDF-1alpha), CXC chemokine receptor 4+ (CXCR 4+) positive cells and endothelial progenitor cells (EPCs) and bone marrow (BM) EPCs levels in local cerebral ischemia/reperfusion injury (CI/IR) rats, so as to study its mechanisms underlying improvement of cerebral ischemia.

Methods: A total of 54 SD rats were randomly divided into normal control, model, and EA groups. The latter two groups were further divided into 1 d, 2 d, 3 d and 7 d subgroups (4 time-points), respectively.
