鉴于目前心脏再生治疗方法的疗效有限,人们探索了组织工程学方法,以期为受损的心脏组织提供机械支持,传递心脏保护分子,并改进基于细胞的治疗技术。可注射水凝胶是一种特别有吸引力的系统,因为它们有望成为一种微创治疗方法。此外,基于无细胞藻酸盐的可注射水凝胶已经在心肌梗塞(MI)患者中进行了临床测试,显示出保留了左室(LV)指数和左室射血分数(LVEF)。因此,避免了心肌梗死后的不良重构。在这篇综述中,我们概述了用于心脏组织工程的各种可注射水凝胶系统的设计和工程方面的最新进展,包括天然系统和合成系统的比较,重点是仿生心脏材料的理想特性。用于心脏组织工程的可注射水凝胶可用于体外模型、体内临床前目的和临床试验。
In light of the limited efficacy of current treatments for cardiac regeneration, tissue engineering approaches have been explored for their potential to provide mechanical support to injured cardiac tissues, deliver cardio-protective molecules, and improve cell-based therapeutic techniques. Injectable hydrogels are a particularly appealing system as they hold promise as a minimally invasive therapeutic approach. Moreover, injectable acellular alginate-based hydrogels have been tested clinically in patients with myocardial infarction (MI) and show preservation of the left ventricular (LV) indices and left ventricular ejection fraction (LVEF). Thus, avoiding adverse remodeling post MI. In this review, we provide an overview of recent developments that have occurred in the design and engineering of various injectable hydrogel systems for cardiac tissue engineering efforts, including a comparison of natural vs synthetic systems with emphasis on the ideal characteristics for biomimetic cardiac materials. Injectable hydrogels for cardiac tissue engineering can be used for in vitro models, in vivo preclinical purposes and for clinical trials.
