机械力是许多生物过程不可或缺的,然而,目前的技术不能映射的大小和方向的微微牛顿分子力。在这里,我们描述了分子力显微镜,利用分子张力探针和荧光偏振显微镜来测量细胞力的大小和3D方向。我们绘制了小鼠成纤维细胞和人类血小板中基于整合素的牵引力的方向,揭示了受力结构组织与其力矢量之间的对齐。分子力显微镜采用荧光偏振显微镜和分子张力传感器的组合来确定细胞力的方向。该技术已被证明用于血小板和成纤维细胞中的整合素介导的力。
Mechanical forces are integral to many biological processes; however, current techniques cannot map the magnitude and direction of piconewton molecular forces. Here, we describe molecular force microscopy, leveraging molecular tension probes and fluorescence polarization microscopy to measure the magnitude and 3D orientation of cellular forces. We mapped the orientation of integrin-based traction forces in mouse fibroblasts and human platelets, revealing alignment between the organization of force-bearing structures and their force vectors. Molecular force microscopy employs a combination of fluorescence polarization microscopy and molecular tension sensors to determine the orientation of cellular forces. The technology is demonstrated for integrin-mediated forces in platelets and fibroblasts.
