Performing Bronchoalveolar Lavage in the Mouse.

Area of Science:

• Pulmonary and Respiratory Medicine
• Immunology
• Animal Models

Background:

• Bronchoalveolar lavage (BAL) is crucial for assessing airway inflammation in human and murine models.
• It enables the study of cellular and molecular components in pulmonary airways, vital for diseases like asthma and COPD.
• Reproducible BAL procedures are essential for reliable mouse airway research.

Purpose of the Study:

• To describe a basic, rapid, and inexpensive procedure for collecting BAL fluid and cells in mice.
• To ensure efficient and reproducible cell counting for accurate analysis of airway inflammation.
• To provide a standardized method for immunological and inflammatory cell population sampling in murine models.

Main Methods:

• Detailed description of a reproducible Bronchoalveolar lavage (BAL) technique for mouse models.
• Focus on efficient collection of BAL fluid and cells.
• Methodology supports subsequent cellular analysis and quantification.

Main Results:

• The described BAL procedure is highly reproducible, rapid, and cost-effective.
• Facilitates efficient counting of collected cells.
• Enables reliable assessment of cellular and molecular inflammatory components.

Conclusions:

• The presented BAL method is a valuable tool for standardized airway research in mice.
• It supports the investigation of inflammatory cell influx in various respiratory disease models.
• This technique is essential for combining cell counts with molecular analyses (ELISA, qPCR, etc.) for comprehensive airway inflammation assessment.
