Verhoeff-Van Gieson (VVG) is a histological staining technique used to visualize elastic fibers and collagen in tissue sections. The stain was named after German pathologist Friedrich Verhoeff and Dutch pathologist Pieter Van Gieson, who developed the technique in the late 19th century.
Under the microscope, elastic fibers will appear black or dark brown, while collagen fibers will appear red or pink. The VVG stain is particularly useful in identifying and visualizing elastic fibers in tissues, such as in the aorta or skin.
Overall, the VVG stain is an important staining technique in histology, allowing for the visualization and identification of elastic and collagen fibers in tissue sections.
