Mapping Aortic Valve Cells Using the FLUOVIEW FV3000 Microscope

The valves of a healthy adult heart allow blood to flow to the lungs and throughout the body. However, the structure and function of the aortic valve are vulnerable to environmental stress. Understanding the cellular composition of the aortic valve is critical for the treatment of aortic valvular diseases, such as bicuspid aortic valve calcification and leaflet degradation.

By using the FLUOVIEW FV3000 confocal microscope, we successfully confirmed the contribution of Tie2 positive cells to the aortic valve identified by lineage tracing technology.

Easily Perform Macro-to-Micro Imaging of Murine Aortic Valve Cells

Thanks to the 1.25X macro imaging objective, we could easily and quickly acquire a large overview of an aortic valve slice with a single image. By simply dragging the mouse on the overview image, the FV3000 confocal microscope’s macro-to-micro function enabled us to quickly locate target cells and then observe the fine structures in a region of interest using a high-resolution objective lens.
