Introduction
The bottom germ layer of the early trilaminar embryo germ layers (ectoderm, mesoderm and endoderm) formed by gastrulation.
The endoderm contributes the epithelia and glands of the gastrointestinal tract and respiratory tract. This layer also contributes to the associated gastrointestinal tract organ development (liver and pancreas).
The layer appears to initially be influenced by the overlying notochord and subsequently by a range of growth factors regulating growth and differentiation.
Note that this layer also lines the extra-embryonic yolk sac, which is initially continuous with the intra-embryonic endoderm.
