intermediate mesoderm

Intermediate mesoderm is a type of mesoderm that is located between the paraxial mesoderm and the lateral plate.

Intermediate mesoderm develops into the part of the urogenital system (kidneys and gonads).

Intermediate mesoderm is distinct from the lateral mesoderm, as it is not influenced by the secretion of BMP-4 (BMP4) by the ectoderm, possibly due to the lack of receptors.

- series of short evaginations from each segment grows dorsally caudally

- pronephric duct arises in the intermediate mesoderm just ventral to the anterior somites
- grows caudally until it becomes the cloaca
