Mesendoderm Cells

Mesendoderm cells pass through the primitive streak and generate two germ lines - the mesoderm and the endoderm.

The axial mesendoderm contains progenitor cells of the anterior definitive endoderm and lateral plate mesoderm, and as such, contains the progenitor cells of both the foregut endoderm (e.g. lung, liver and pancreas) and their associated mesoderms.
