Executive Industry Relevance

Direct visualization and quantification of tunneling nanotubes (TNTs) using 3D volume imaging addresses a critical gap in understanding intercellular communication mechanisms relevant to disease models. This capability enables mechanistic de-risking and target validation in neurodegeneration, viral pathogenesis, and oncology pipelines. Reliable TNT identification supports predictive confidence at early discovery and translational inflection points.
