2. Somite Development - Early Somite
- Paraxial mesoderm towards the rostral (cranial) end, begins to segment forming the first somite.
- Somites are then sequentially added caudally in pairs.
- The somite surface cells undergo a mesenchymal to epithelial transition, forming a transient epithelial covering on each somite.
- The mesoderm under the surface remains as mesenchyme and proliferates.
- The early forming somites have a cavity (somitocoel) in their core that is lost as the somite matures.
Note - the cartoons show just the embryo righthand side mesoderm development (the same events occur on the lefthand side).
