Abstract
Objective To explore whether endothelial progenitor cells(EPCs) in patients with cerebrovasculardiseases could express high level of osteocalcin.Methods We studied 51 patients with acute cerebrovascular diseases and 30 sex- and age- matchedcontrol subjects. EPCs in peripheral blood mononuclear cells were analyzed by flow cytometry.Results Patients with cerebral ischemia had about three-fold increase of the number and thepercentage of osteocalcin positive(OCN+) EPCs compared with control group(P<0.01). Patients withvessel calcification had higher percentage of OCN+EPCs than those without calcification(P=0.033).However, the degree of stenosis had no direct correlation with osteocalcin expression(P=0.672).Logistic analysis showed that the percentage of OCN+EPCs was an independent risk factor forcerebral ischemia(odds ratio=1.143,95% confidence intervals 1.060-1.232).Conclusion Circulating endothelial progenitor cells in patients suffering from cerebral ischemiacan express osteocalcin and act as a negative factor for vascular lesion rather than normal repair.The percentage of OCN+EPCs may be used as a potential cell marker for ischemic cerebrovasculardiseases.关键词
