The Fine Structure of Imaginal Disks
How are disks organized at the cellular level? Specifically, how many cell layers and cell types constitute a disk?
Is the determined state, for whose exploration imaginal disks appear so suited, expressed morphologically? Are the cells of a wing disk, e.g., distinguishable from those of an eye disk at the fine structural level? Or are cells of known lineage within a disk distinguishable from their neighbors? And finally, is transdetermination expressed at the morphological level?
How do the cells of imaginal disks, derivatives of the larval hypodermis, respond to the humoral control that is known to govern the larval molts?
How do the internally located disks form the exterior adult appendages during morphogenesis?
Is there a morphological parallel to the cell-cell communication that might convey positional information when the adult pattern of surface specializations is laid down?
Does selective cell death occur during disk morphogenesis?
