Somite formation begins as paraxial mesoderm cells become organized into whorls of cells called somitomeres. The somitomeres become compacted and bound together by an epithelium, and eventually separate from the presomitic paraxial mesoderm to form individual somites.
What is Somite formation?
Somites are precursor populations of cells that give rise to important structures associated with the vertebrate body plan and will eventually differentiate into dermis, skeletal muscle, cartilage, tendons, and vertebrae. ... Formation begins as paraxial mesoderm cells organize into whorls of cells called somitomeres.
What is Somite segmentation?
The somites are formed by segmentation from the anterior end of the presomitic mesoderm (PSM), which is unsegmented and posterior to the most recently formed somite. Each somite is subdivided into anterior (rostral) and posterior (caudal) compartments that differ in their properties and gene expression.
