{The migration of intra-embryonic mesoderm occurs between the ectoderm and endoderm to give rise to: | |||

|| During gastrulation in week 3 to 4, intra-embryonic mesoderm, or simply "mesoderm" occurs between the ectoderm and endoderm forming the {{somite}}s. Extra-embryonic mesoderm lies outside the embryo and is associated with the placenta and fetal membranes. | |||
