Movat's stain

Movat's stain is a histological stain that is used to visualize connective tissue, muscle tissue, elastic fibers, collagen, and cell nuclei. It was developed by Henry Zoltan Movat, a Canadian pathologist, in 1955.

Overview[edit | edit source]

Movat's stain is a pentachrome stain, meaning it uses five colors to differentiate between different types of tissue. The stain is particularly useful for studying the structure and composition of the heart and blood vessels, as it can highlight the presence of fibrin, mucin, collagen, elastin, and cell nuclei.

Procedure[edit | edit source]

The procedure for Movat's stain involves several steps. First, the tissue sample is fixed and dehydrated. Then, it is stained with Alcian blue, which colors mucin and other acid mucopolysaccharides blue. Next, the sample is treated with Verhoeff's stain, which colors elastin black. The sample is then differentiated in ferric chloride, which removes the Verhoeff's stain from all tissues except elastin. The sample is then stained with crocein scarlet-acid fuchsin, which colors fibrin and collagen red and muscle and cell nuclei yellow. Finally, the sample is treated with a solution of acetic acid and methyl alcohol, which differentiates the crocein scarlet-acid fuchsin stain.

Applications[edit | edit source]

Movat's stain is widely used in pathology to study the structure and composition of various tissues. It is particularly useful for studying diseases that affect the heart and blood vessels, such as atherosclerosis and aneurysm. The stain can also be used to study the structure and composition of other tissues, such as the lungs, kidneys, and skin.
