Age-related changes in the coat of C57BL/6J mice. Due to individual ageing processes, age-related coat changes may be more or less pronounced in mice of different ages. The pictures shown are deliberately not sorted by real age but by signs of ageing. Each picture shows different individuals of C57BL/6J mice. A and B: female, unremarkable appearance, smooth, close-lying, completely black and full coat, C: male, smooth, close-lying black coat, first light spot visible (red arrow), D: male, coat not lying flat but standing up slightly (no piloerection), light spots visible (red arrows), E: male, coat grey mottled, coat not smooth but slightly protruding (no piloerection), F: female, coat colour rather greyish than black, coat dull and slightly protruding (no piloerection).
