心脏瓣膜在心动周期期间控制心脏内的单向血流。他们有一个了不起的能力,以承受心脏的苛刻的机械环境,实现寿命耐久性的过程涉及不断重塑的细胞外基质。这篇综述的重点是心脏瓣膜功能生理学,深入了解疾病引起的瓣膜几何形状改变,组织应力和随后的细胞机械生物学反应和组织重塑之间的联系。我们开始与心脏瓣膜生理学的基本原理和瓣膜间质细胞(VIC)的特性和功能的概述。然后,我们提供了一个概述,目前的实验和计算方法,连接维克机械生物学响应器官和组织水平的变形,提高我们的理解的基础功能生理心脏瓣膜。最后,我们总结了未来的趋势,并提供了心脏瓣膜机械生物学的未来,特别是,多尺度建模方法,研究发展的潜在方向和可能的挑战的前景。
Heart valves control unidirectional blood flow within the heart during the cardiac cycle. They have a remarkable ability to withstand the demanding mechanical environment of the heart, achieving lifetime durability by processes involving the ongoing remodeling of the extracellular matrix. The focus of this review is on heart valve functional physiology, with insights into the link between disease-induced alterations in valve geometry, tissue stress, and the subsequent cell mechanobiological responses and tissue remodeling. We begin with an overview of the fundamentals of heart valve physiology and the characteristics and functions of valve interstitial cells (VICs). We then provide an overview of current experimental and computational approaches that connect VIC mechanobiological response to organ- and tissue-level deformations and improve our understanding of the underlying functional physiology of heart valves. We conclude with a summary of future trends and offer an outlook for the future of heart valve mechanobiology, specifically, multiscale modeling approaches, and the potential directions and possible challenges of research development.
