Methods to localize cell specific alterations within the 3D context of the lung

Area of Science:

• Pulmonary Pathology
• Histology
• Medical Imaging

Background:

• The lung's heterogeneous nature necessitates spatial analysis for understanding pathologies.
• Accurate lesion localization is crucial for translating preclinical findings and developing targeted treatments.
• Bronchopulmonary dysplasia serves as a model pathology, but methods are broadly applicable.

Purpose of the Study:

• To review common histological methods for lung pathology analysis.
• To explore the potential of these methods for assessing cellular features and spatial location.
• To detail advanced imaging integration for comprehensive lung pathology research.

Main Methods:

• Review of common histological techniques for cellular and spatial assessment.
• Exploration of morphological characteristics and intracellular states (cell cycle, cell death).
• Integration of multiple imaging modalities (e.g., microscopy, computed tomography) into analysis pipelines.

Main Results:

• Histological methods can evaluate cellular features and spatial localization of lung pathologies.
• Combining microscopy and computed tomography enables 3D spatial assessment alongside cellular details.
• Immunohistochemical markers can be integrated for specific protein detection.

Conclusions:

• Integrated imaging analysis pipelines offer a powerful tool for lung pathology research.
• This approach facilitates both transitional and longitudinal studies of lung diseases.
• The described methods support a deeper understanding of lung heterogeneity in disease contexts.
