[Abstract]  Ex vivo biophysical measurements provide valuable insights into understanding both physiological and pathogenic processes. One critical physiological mechanism that is regulated by these biophysical properties is cilia-generated flow that mediates mucociliary clearance, which is known to provide protection against foreign particles and pathogens in the upper airway. To measure ciliary clearance, several techniques have been implemented, including the use of radiolabeled particles and imaging with single-photon emission computerized tomography (SPECT) methods. Although non-invasive, these tests require the use of specialized equipment, limiting widespread use. Here we describe a method of ex vivo imaging of cilia-generated flow, adapted from previously reported methods, ... [摘要]  [摘要 ] 体外生物物理测量为了解生理和致病过程提供了宝贵的见识。由这些生物物理特性调节的一种关键的生理机制是纤毛产生的血流,它介导了粘膜纤毛清除,已知它可以抵抗上呼吸道中的异物和病原体。为了测量睫毛清除率,已实施了多种技术,包括使用放射性标记的颗粒和使用单光子发射计算机断层扫描(SPECT)方法进行成像。这些测试虽然是非侵入性的,但需要使用专用设备,从而限制了其广泛使用。这里我们描述一种离体方法 对纤毛产生的血流进行成像,并采用以前报道的方法进行改编,以使研究人员更易于访问并获得更高的通量。我们在安乐死后迅速从小鼠身上切除气管,将其纵向切割并将其放置在内部制作的幻灯片中。我们应用荧光颗粒在荧光显微镜下测量颗粒的运动,然后使用ImageJ进行分析,从而可以计算不同条件下纤毛产生的流体流量。该方法能够以最少的投资或专用设备进行组织中的离体测量,从而有机会研究和发现与气管的睫状运动在生理和疾病方面相关的重要生物物理特性。

[背景 ] 多样的生物物理特性的组合物,每个辅助指定功能,弥补人体。一个重要的例子是在许多不同器官系统中产生血流,包括中枢神经系统(Olstad 等人,2019),生殖道(Afzelius 等人,1978; Yuan ...
