Imaging intravitale basato su finestra cranica in un modello murino: una tecnica di imaging per studiare il comportamento delle cellule tumorali pre-iniettate nel cervello di un modello murino

Executive Industry Relevance

Intravital imaging via cranial windows enables real-time visualization of cancer cell dynamics in live murine brains, supporting mechanistic de-risking in oncology target validation. This approach provides quantitative, longitudinal data on tumor cell migration and microenvironment interactions, enhancing predictive confidence in preclinical models. It bridges discovery biology with translational relevance by capturing functional phenotypes in disease-relevant systems.

Implementation Considerations

• Requires expertise in murine surgery, cranial window implantation, and multiphoton microscopy operation.
• Depends on inverted microscopes with multiphoton capability, environmental control chambers, and fluorescent protein-expressing cell lines.
• Necessitates cross-team standardization for imaging protocols, z-stack parameters, and analysis software use across sites.
• Involves adaptation considerations when applying to different tumor models or brain regions while maintaining imaging fidelity.
• Limited by surgical invasiveness and recovery constraints, which may affect longitudinal study design and animal welfare compliance.
