Endogenous pigment

Endogenous pigments are pigments that are made in the body. A distinction is made between hematogenic pigments such as hemoglobin and its derivatives and autogenous pigments such as melanin or lipofuscin .

Exogenous pigments, on the other hand, penetrate the cell from the outside and are stored in the cytoplasm , as they cannot be broken down due to their chemical structure. A tattoo or an injury can force colored foreign bodies into the cytosol. Inhaled soot particles are absorbed by alveolar macrophages and color the lung tissue black.
