インビボ マウス顎下腺における血管透過性検出

Overview

This study evaluates the endothelial barrier function of the submandibular gland (SMG) using in vivo imaging techniques. Fluorescent tracers of varying molecular weights were injected into test animal models, demonstrating how molecular permeability can be assessed using two-photon laser scanning microscopy.
