METACHROMASIA Meaning and
Definition
-
Metachromasia is a term used in biology and histology to describe a phenomenon where certain substances or dyes appear to change color when exposed to certain conditions. This change occurs due to the interaction between the substance being stained and the stain itself. Specifically, metachromasia refers to the ability of a dye to undergo a color shift, typically from a blue or purple shade to a pink or red shade, when binding to certain components within a cell or tissue sample.
Metachromasia occurs because the dye molecules absorb and reflect light in a different manner when they interact with specific substances. This interaction can alter the wavelengths of light that are absorbed and emitted, resulting in a change in color perception. Examples of substances that can exhibit metachromasia include certain cellular components like mast cell granules, mucin, or amyloid deposits.
In histological studies, metachromasia is often utilized to identify and distinguish specific substances or structures within a sample. By staining with suitable dyes that demonstrate metachromasia, researchers can highlight the presence and distribution of particular compounds, aiding in the characterization and understanding of cellular or tissue components. Metachromasia is a valuable tool in the field of histology, providing visual cues that can help differentiate various structures and analyze the composition of different biological samples.

Etymology of METACHROMASIA
The word "metachromasia" is derived from the Greek roots "meta" meaning "beyond" or "change" and "chromasia" meaning "coloration". "Meta" indicates a change or alteration, while "chromasia" refers to the coloring or staining of a substance. Therefore, "metachromasia" can be interpreted as the property of changing or altering the coloration of a substance.
