| Research Abstract |
At first, we newly developed scanning electron microscopy technique using a formic acid digestion with vascular casts, which revealed, in detail, the three-dimensional(3D) architecture of delicate elastic fibers in small vessels. This method could successfully visualized the three-dimensional architecture of elastic fibers in small various sized of blood vessels, even arterioles and venules. Furthermore, the new method revealed the 3D architectures of corrupted internal elastic lamina.
