쥐 모델에서 교모세포종의 Two-Photon Intravital Microscopy

Executive Industry Relevance

Overcoming the blood-brain barrier remains a critical challenge in the development of effective therapeutics for glioblastoma and other CNS malignancies. Two-photon intravital microscopy (2P-IVM) enables direct, real-time visualization of nanoparticle and macromolecule distribution in preclinical brain tumor models, providing actionable insights for optimizing drug delivery strategies. This capability supports predictive confidence at the interface of discovery biology and translational research, informing portfolio decisions on CNS-targeted assets.
