Lipofuscin is the name given to fine yellow-brown pigment granules composed of lipid -containing residues of lysosomal digestion.[ 1] [ 2] It is considered to be one of the aging or "wear-and-tear" pigments, found in the liver , kidney , heart muscle, retina, adrenals , nerve cells, and ganglion cells.[ 3]
