Hepatic diverticulum

For use of the term in molluscs, see Diverticulum (mollusc).

The hepatic diverticulum (or liver bud) is a primordial cellular extension of the embryonic foregut endoderm that gives rise to the parenchyma of the liver and the bile duct.^[1] It typically differentiates from the endoderm in the third or fourth week of gestation and is reabsorbed in tubular structures of the septum transversum by the eighth week. ^[2]
