Depigmented refers to the condition of a substance, tissue, or organism losing or lacking its usual pigment, resulting in a lighter coloration or a complete absence of color. This loss of pigment, often caused by a reduction in melanin, can occur due to various factors, including genetic predispositions, environmental influences like UV exposure, or underlying medical conditions affecting melanocyte function. The extent of depigmentation can vary, manifesting as subtle lightening to noticeable white patches or complete bleaching in affected areas. This is a signifier to an underlaying problem.
Depigmented meaning with examples
- The dermatologist examined the skin, noting several depigmented patches that suggested vitiligo, an autoimmune disease. This resulted in a lighter skin tone in these affected areas, differing in intensity from surrounding tissue. Further tests were ordered to confirm the diagnosis and determine the potential causes, including treatment for slowing the spread. The appearance was a stark visual cue.
- Prolonged sun exposure caused some of the coral reefs to display a depigmented appearance, making the corals a ghostly white color as they lost their vibrant hues. This bleaching was a sign of stress due to the elevated water temperatures. Researchers were deeply concerned about the future, indicating the ocean was not adapting fast enough to keep up. This was a large scale phenomenon.
- The leaves of the genetically modified plant showed depigmented streaks, indicating a disruption in the chlorophyll production process. This presented a visual cue of poor health and a lack of nutrients. The scientist suspected a viral infection or nutrient deficiency. Further investigation was needed to identify the precise factor. Such examples allowed quick identification of environmental stress.
- The artisan observed the depigmented areas on the wood carving, a result of the wood's age and exposure to sunlight. This resulted in uneven staining of the wood. This was an acceptable element, considering the product's weathered look. The artisan carefully worked to even out the finish, highlighting the natural grain's pattern. This added character and history.
- The medical examiner noted the depigmented areas surrounding the scar tissue, a sign of the body's natural healing response. The new cells didn't have the same pigment producing capacity, indicating a loss of melanin. Further testing was not performed. This was typical, so the case was closed.
