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.
