Eye development in Drosophila: formation of the eye field and control of differentiation.

摘要: Publisher Summary This chapter discusses the early stages of eye development in Drosophila , focusing on mechanisms that determine global pattern rather than those involved establishment specific cell fates. It specification disk to form an eye, control morphogenetic furrow initiation and propagation, coordination growth with differentiation. Most adult structures, including develop from imaginal disks. These are groups cells set aside embryo grow differentiate inside larva evert become functional during metamorphosis. Differentiation is progressive, moving across a wavelike manner posterior anterior. The front wave marked by indentation known as furrow. division occurs unpatterned anterior furrow, while side organized into clusters ommatidia. develops remarkably coordinated manner. Its differentiation begins at precisely defined point expands steady rate, laying down rows evenly spaced ommatidial founder cells.
