Pattern formation in imaginal discs.

Abstract excerpt

Imaginal discs are sacs of folded epithelium arising during embryogenesis. They proliferate during the larval instars, and at metamorphosis secrete the adult cuticle, therefore being responsible for the characteristic surface patterning of this insect. Each disc has intrinsic growth controls and their cell lineage shows constraints known as compartments. Spatial patterns emerge through interaction between...
