A group of pigments that accumulate in several body tissues, particularly the myocardium, and are associated with the ageing process.
Granules of pigments found in aging tissues; highly insoluble lipid-protein complexes held together by multiple cross-linkages.
Insoluble fatty pigment present in cardiae and smooth muscle cells; represents indigestible portions of cells that have been phagocytosed as a part of normal aging. Sometimes called the aging pigment, it has no direct harmful effects on the cell.
A brownish pigment staining with certain fat stains. It is most common in the cells of heart muscle, nerves, and liver and is normally contained within lysosomes.
An insoluble fatty pigment found in aging cells. It is the residue of cellular or extracellular material that the cells have ingested but not completely digested.
