肺组织学通常用于研究气腔细胞在肺稳态和疾病发病机制中所提供的贡献。然而,常用的基于滴注的固定方法可以将空腔细胞和粘液转移到终末气道中,并可以改变组织形态。相比之下,血管灌注固定技术在保留空腔和粘膜内层细胞的位置和形态方面更胜一筹。然而,如果不同时施加气道正压,肺部区域可能塌陷,毛细血管可能凸入肺泡腔,导致肺部解剖结构变形。在此,我们描述了一种在血管灌注固定期间进行充气的廉价方法,以保留小鼠肺部气道、肺泡细胞和间质的形态和位置,用于下游组织学研究。恒定的气压通过气管从密封的充气室输送到肺部,该室通过可调节的液柱维持压力,同时固定剂通过右心室灌注。
Lung histology is often used to investigate the contributions provided by airspace cells during lung homeostasis and disease pathogenesis. However, commonly used instillation-based fixation methods can displace airspace cells and mucus into terminal airways and can alter tissue morphology. In comparison, vascular perfusion-fixation techniques are superior at preserving the location and morphology of cells within airspaces and the mucosal lining. However, if positive airway pressure is not simultaneously applied, regions of the lungs may collapse and capillaries may bulge into the alveolar spaces, leading to distortion of the lung anatomy. Herein, we describe an inexpensive method for air-inflation during vascular perfusion-fixation to preserve the morphology and location of airway and alveolar cells and interstitium in murine lungs for downstream histologic studies. Constant air pressure is delivered to the lungs via the trachea from a sealed, air-filled chamber that maintains pressure via an adjustable liquid column while fixative is perfused through the right ventricle.
