Endothelial progenitor cells derived from the peripheral blood of halfpipe- snowboarding athletes display specific functional properties

Abstract

In this study, we compared the functional properties of endothelial progenitor cells (EPCs) derived from halfpipe-snowboarding athletes who train under hyperoxic conditions with those derived from normal subjects who lived under normoxic conditions. Peripheral blood-derived EPCs were isolated from both halfpipe-snowboarding athletes and normal humans. Cellular growth dynamics, lipoprotein transport, and gene expression of cultured EPCs were compared between the two groups of cells. Results indicate that cytoactivity of EPCs from athletes was higher than that of EPCs from control subjects. This study suggests that function of EPCs from snowboarding athletes may be better than that of EPCs from normal humans, which demonstrates the benefits of training under hyperoxic conditions.
