Abstract
Fibrosis is the pathophysiologic hallmark of chronic rejection after lung transplantation and the foremost hurdle to long-term recipient survival. Several murine lung transplantation models are available for the study of chronic rejection. However, they display heterogeneous results regarding fibrotic changes of the graft, and the histologic extent of fibrosis is mostly reported qualitatively. Therefore, a spatially resolved approach that allows for statistical analysis can aid in evaluating fibrosis in these models. This study presents Picrosirius Red staining for a semiquantitative evaluation of collagen organization in murine lung allografts and compares it to standard Hematoxylin and Eosin, Masson's Trichrome, and Herovici's stains. Staining was performed on sections from two different murine transplantation models based on minor and major histocompatibility complex (MHC) mismatches. The method was established for semiquantitative analysis of collagen organization in whole lung sections. Thus, it can serve as a tool for murine experimental models of fibrotic lung diseases.
期刊介绍:
JoVE, the Journal of Visualized Experiments, is the world''s first peer reviewed scientific video journal. Established in 2006, JoVE is devoted to publishing scientific research in a visual format to help researchers overcome two of the biggest challenges facing the scientific research community today; poor reproducibility and the time and labor intensive nature of learning new experimental techniques.
