血液动力学和间质机械力对体内内皮生物学的影响已经被认识了超过半个世纪,调节血管网络发育、稳态功能和血管疾病的进展。使用二维(2D)基板上的内皮细胞培养物的研究已经阐明了重要的机制,通过该机制,微环境应力被感知并转导成化学信号应答。然而,最近的研究在体内和三维(3D)在体外模型的血管床,使以前不可能在传统的二维培养系统的力和细胞行为的调查。这些研究支持了一个发展中的范例,即血管生态位的3D化学机械结构影响内皮细胞如何感知和响应微环境力。我们提出了不断发展的概念,内皮力传感和机械信号,并强调最近的见解,从体内和3D体外血管模型。
The effects of hemodynamic and interstitial mechanical forces on endothelial biology in vivo have been appreciated for over half a century, regulating vessel network development, homeostatic function, and progression of vascular disease. Investigations using cultures of endothelial cells on two-dimensional (2D) substrates have elucidated important mechanisms by which microenvironmental stresses are sensed and transduced into chemical signaling responses. However recent studies in vivo and in three-dimensional (3D) in vitro models of vascular beds have enabled the investigation of forces and cellular behaviors previously not possible in traditional 2D culture systems. These studies support a developing paradigm that the 3D chemo-mechanical architecture of the vascular niche impacts how endothelial cells both sense and respond to microenvironmental forces. We present evolving concepts in endothelial force sensing and mechanical signaling and highlight recent insights gained from in vivo and 3D in vitro vascular models.
