中文摘要：

内皮祖细胞是成熟血管内皮细胞的前体细胞，属于干细胞群体，其在血管再生与修复方面的应用越来越受到关注。肺动脉高压作为一种致死性很高的肺血管疾病，其发病与血管内皮损伤密切相关。目前的研究证实，内皮祖细胞在肺动脉高压血管内皮修复中具有重要作用，内皮祖细胞移植有可能成为临床治疗肺动脉高压的一种有效手段。

英文摘要：

Endothelial progenitor cells are precursors of mature vascular endothelial cells, which belong to stem cell populations. More and more researchers pay close attention to the important role of endothelial progenitor cells in vascular regeneration and repair. Pulmonary hypertension is a fatal pulmonary vascular disease. The pathogenesis of pulmonary hypertension relates closely with blood vessel endothelium injury, Present studies have proved that endothelial progenitor cells play important roles in blood vessel endothelium repair of pulmonary hypertension,and transplantation of endothelial progenitor cells could be applied as an effective method for pulmonary hypertension.
