Quantitative lung tissue analysis for asthma and COPD research faces challenges due to varying methods. Digital image analysis (DIA) offers potential but requires standardization for reliable inflammatory cell and gene expression studies.

Area of Science:

  • Pulmonary Pathology
  • Biomedical Imaging
  • Molecular Diagnostics

Background:

  • Workshop convened experts in pulmonary and pathology research to address challenges in quantitative lung tissue analysis.
  • Variability in tissue sampling, processing, and staining techniques hinders data comparability in asthma and COPD studies.
  • Focus on inflammatory cell patterns and gene expression in bronchial and parenchymal lung tissues.

Framework:

  • Assessed the validity and applicability of current techniques for quantitative examination.
  • Explored digital image analysis (DIA) versus manual scoring for cell counting and gene/protein expression.
  • Identified key factors impacting quantitative analysis: tissue handling, fixation, staining, and microscope settings.

Implementation:

  • Inventory of available techniques for tissue processing and analysis.
