Facts (generated by robot; please edit if you find it inaccurate)
- Our studies reveal that one of the functions of gbb in the wing imaginal disc is to downregulate dpp expression.
- The imaginal disc is a two-sided sac comprising a columnar cell layer that contains presumptive wing blade (wb) and thorax (t) regions, and an overlying squamous peripodial membrane (pm); it is set aside from the embryonic epidermis and develops at the larval stage.
- Taken together, these observations suggest that, at the beginning of L2, the wing imaginal disc is divided into the presumptive notum and the appendage or 'wing' primordium, and that the wing primordium is undifferentiated with respect to the proximodistal axis.
- fiWhen a fragment of a Drosophila imaginal disc is cultured in growth permissive conditions, it either regenerates the missing structures or duplicates the pattern present in the fragment.
- 435 Research Interests The Drosophila wing imaginal disc is a monolayered epidermal sac.
