Zwei-Photonen-Mikroskopie für die In-vivo-Bildgebung von Mikrogefäßen im Gehirn von Mäusen

Executive Industry Relevance

Two-photon microscopy enables high-resolution in vivo imaging of brain microvasculature, supporting target validation in neurovascular research. This approach provides predictive confidence by visualizing functional capillary networks in disease-relevant systems, aiding mechanistic de-risking for CNS therapeutics. The method supports early discovery by establishing reproducible vascular phenotypes for assay development and translational biomarker alignment.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Scientific Value: Enables interrogation of vascular hypotheses and pathway clarification in neuroinflammatory models.
• Operational Value: Provides functional target validation through direct visualization of blood-brain barrier integrity and perfusion dynamics.
• Predictive Value: Supports portfolio triage by quantifying vascular changes that correlate with disease progression and drug response.

Screening & Assay Development

• Scientific Value: Prepares validated biological systems for downstream compound screening by establishing baseline vascular architecture.
• Operational Value: Ensures assay standardization and reproducibility through consistent fluorescent dye labeling and imaging parameters.
• Scalability: Enables platform reuse across multiple disease models and therapeutic interventions.
