Vascular Endothelial Growth Factor and Endostatin in Angiogenesis After Acute Ischemic Stroke

August 8, 2020 updated by: Hao Chen, Shanghai 6th People's Hospital

Dynamic Changes of Vascular Endothelial Growth Factor and Endostatin in Association With Circulating Endothelial Progenitor Cells After Acute Ischemic Stroke

Vascular endothelial growth factor (VEGF) and Endostatin (ES) participate angiogenesis after cerebral ischemia. Circulating endothelial progenitor cells (EPCs) also play a crucial role in neovascularization and tissue repair after acute ischemic stroke (AIS). The investigators sought to compare the expression of VEGF and ES in serum and the circulating EPCs in patients after AIS with that of healthy control subjects. The investigators obtained peripheral blood and serum samples from study subjects. EPCs in blood samples from AIS patients and healthy controls were quantified by flow cytometry 1 day, 3 days, 5 days and 7 days after AIS. VEGF and ES were measured by enzyme linked immunosorbent assay at the same time points. The relation between them and the relation of them to prognosis of such patients with acute ischemic stroke were assessed.

Study Population

The patient group comprised twenty male and ten female. Their age ranged from 45 to 74 years. Locations of infarct, as evidenced by radiologic and neurologic symptoms or signs, included the territories of the middle cerebral artery (9 cases), the posterior cerebral artery (8 cases) the anterior cerebral artery (6 cases), vertebrobasilar area (5 cases), and watershed area (2 cases with cortical and subcortical low densities crossing typical vascular territories).

Description

Inclusion Criteria:

  • Clinical diagnosis of acute ischemic stroke
