Some Recent Findings
Mesoderm Formation during Gastrulation
|<Flowplayer width="390" height="510" autoplay="true">Mesoderm_001.flv</Flowplayer>||This animation shows the migration of mesoderm throughout the embryonic disc during gastrulation.
The pink arrow show how mesodermal cells spread out between the ectoderm and endoderm layers, forming the third layer of the trilaminar embryo.
Axial process - the arrow running from the primitive node upward is the axial process which will later form the notochord.
There are only 2 regions where no mesoderm is found: buccopharyngeal membrane and cloacal membrane.
Prechordal plate - lies above the buccopharyngeal membrane and is the cardiogenic mesoderm, that will form the heart.
