Early Development of the Liver: A Review

  • Robert L. Peters
Part of the Hepatology book series (H, volume 5)


The earliest sign of liver formation in the developing human embryo antedates any recognizable morphologic anlage. At a developmental time less than 21 post ovulatory days, when the embryo is less than 2.5 mm long, the embryo is a convex caterpillarlike structure, broadly connected to the yolk sac. The infolding that produces the head process, has brought the cardiac mesoderm in close juxtaposition to the broad stalk of the yolk sac. This stalk forms the upright of a T with the horizontal arms making up the fore and hind guts, at this stage.
