心脏病是全世界发病和死亡的主要原因,替代受损心肌的再生疗法每年可以使数百万患者受益。心脏中的多种细胞类型,包括心肌细胞、内皮细胞、血管平滑肌细胞、周细胞和心脏成纤维细胞,通过细胞间信号传导进行通信并调节彼此的功能。尽管在利用人类多能干细胞生成心血管谱系细胞方面已经取得了很大进展,但现在的一个主要挑战是创建组织结构,将微血管循环和传入小动脉整合到这样的工程组织中。心脏和血管组织工程的最新进展将使我们更接近生成功能成熟组织的目标。利用心肌生物学作为设计工程组织并解决植入和整合挑战的基础,我们可以弥合临床上易于处理的工程心脏组织从实验室到临床的差距。
Heart disease is the leading cause of morbidity and mortality worldwide, and regenerative therapies that replace damaged myocardium could benefit millions of patients annually. The many cell types in the heart, including cardiomyocytes, endothelial cells, vascular smooth muscle cells, pericytes, and cardiac fibroblasts, communicate via intercellular signaling and modulate each other’s function. Although much progress has been made in generating cells of the cardiovascular lineage from human pluripotent stem cells, a major challenge now is creating the tissue architecture to integrate a microvascular circulation and afferent arterioles into such an engineered tissue. Recent advances in cardiac and vascular tissue engineering will move us closer to the goal of generating functionally mature tissue. Using the biology of the myocardium as the foundation for designing engineered tissue and addressing the challenges to implantation and integration, we can bridge the gap from bench to bedside for a clinically tractable engineered cardiac tissue.
