In thinking about the development of the wing imaginal disc of Drosophila, what is the significance of 'compartments'?

#Unit 5. Developmental Biology
  1. A compartment is a signaling center that controls antero-posterior patterning
  2. Compartments are developmental units, in that the wing forms from the 'wing compartment'
  3. Compartments are epithelial sacs, set aside during embryogenesis, that will give rise to adult structures such as wings after metamorphosis.
  4. Since cells in adjacent compartments have different lineage histories, adjacent compartments can adopt different fates and differentiation patterns, as in the formation of the anterior and posterior portions of the wing blade.
