... ( ey ), which controls both growth of the entire eye-antennal imaginal disc and fate specification of the eye. We show that Ey also plays a surprising role within cells of the peripodial epithelium to control pattern formation. It regulates the expression of decapentaplegic ( dpp ), which is required...

... they contribute to formation of a complex structure. Early in development, the wing primordium is subdivided into a thin layer of peripodial epithelium (PE) and an apposing thickened layer of pseudostratified columnar epithelium (CE), known as the disc proper (DP). The DP gives rise to the wing blade, hinge...

...Kimberly D. McClure; Gerold Schubiger Imaginal discs of Drosophila provide an excellent system with which to study morphogenesis, pattern formation and cell proliferation in an epithelium. Discs are sac-like in structure and are composed of two epithelial layers: an upper peripodial epithelium...

...Luis Alberto Baena-López; José Carlos Pastor-Pareja; Jaime Resino Imaginal discs contain a population of cells, known as peripodial epithelium, that differ morphologically and genetically from the rest of imaginal cells. The peripodial epithelium has a small contribution to the adult epidermis...
