Stimulated by the leading mortalities of cardiovascular diseases (CVDs), various types of cardiovascular biomaterials have been widely investigated in the past few decades. Although great therapeutic effects can be achieved by bare metal stents (BMS) and drug-eluting stents (DES) within months or years, the long-term complications such as late thrombosis and restenosis have limited their further applications. It is well accepted that rapid endothelialization is a promising approach to eliminate these complications. Convincing evidence has shown that endothelial progenitor cells (EPCs) could be mobilized into the damaged vascular sites systemically and achieve endothelial repair in situ, which significantly contributes to the re-endothelialization process. Therefore, how to effectively capture EPCs via specific molecules immobilized on biomaterials is an important point to achieve rapid endothelialization. Further, in the context of predictive, preventive, personalized medicine (PPPM), the abnormal number alteration of EPCs in circulating blood and certain inflammation responses can also serve as important indicators for predicting and preventing early cardiovascular disease. In this contribution, we mainly focused on the following sections: the definition and classification of EPCs, the mechanisms of EPCs in treating CVDs, the potential diagnostic role of EPCs in predicting CVDs, as well as the main strategies for cardiovascular biomaterials to capture EPCs.
在心血管疾病(CVDs)主要致死率的刺激下,过去几十年间对各类心血管生物材料展开了广泛研究。尽管裸金属支架(BMS)和药物洗脱支架(DES)在数月或数年之内能取得显著的治疗效果,但诸如晚期血栓形成和再狭窄等长期并发症限制了它们的进一步应用。人们普遍认为,快速内皮化是消除这些并发症的一种有前景的方法。有确凿证据表明,内皮祖细胞(EPCs)可被全身动员至受损血管部位并实现原位内皮修复,这对再内皮化过程有显著贡献。因此,如何通过固定在生物材料上的特定分子有效捕获EPCs是实现快速内皮化的关键所在。此外,在预测、预防、个性化医疗(PPPM)的背景下,循环血液中EPCs数量的异常变化以及某些炎症反应也可用作预测和预防早期心血管疾病的重要指标。在本论文中,我们主要聚焦于以下几个方面:EPCs的定义与分类、EPCs治疗CVDs的机制、EPCs在预测CVDs方面的潜在诊断作用,以及心血管生物材料捕获EPCs的主要策略。
