Illustrative movies of 3D render of GLUT4-GFP in ultrathick sections of cleared mouse heart. Movie of 3D render of GLUT4-GFP fluorescence (green) within a whole mount of optically cleared 3-mm thick mouse ventricular heart section. Specimen was imaged using the Mesolens system over a 5 mm × 5mm × 3mm volume using a z-step size of 5 μm as described in Method.
