The wingless signalling pathway and the patterning of the wing margin in Drosophila
J.P. Couso, S.A. Bishop, A. Martinez Arias
Development 1994 120: 621-636;

Summary

The margin of the wing of Drosophila is defined and patterned from a stripe of cells expressing the wingless (wg) gene that is established during the third larval instar in the developing wing blade. The expression of the genes cut and achaete in a small domain in the prospective wing margin region reflects the activity of wg and probably mediate its function. Our results indicate that, in the wing margin, the wingless signal requires the activity of at least three genes: armadillo (arm), dishevelled (dsh) and shaggy (sgg) and that the functional relationship between these genes and wg is the same as that which exist during the patterning of the larval epidermis. These observations indicate that arm, dsh and sgg encode elements of a unique ‘wingless signalling pathway’ that is used several times throughout development.

Interviews — Bénédicte Sanson and Kate Storey

Bénédicte Sanson and Kate Storey

Hear from Bénédicte Sanson, winner of the BSDB’s Cheryll Tickle medal, and Kate Storey, winner of the BSDB’s Waddington Medal, as they discuss their research, the future of the field and the importance of collaboration.

Review Commons launches

We're excited to be an affiliate journal for Review Commons, the ASAPbio/EMBO platform for high-quality journal-independent peer-review in the life sciences, which went live on 09 December.

Early-career researchers can apply for up to £2,500 to offset the cost of travel and expenses to make collaborative visits to other labs around the world. Read about Peter’s experience in Switzerland, where he joined forces with the Lutolf lab to refine a protocol for producing gastruloids.

Publishing peer review reports

To continue working towards transparency around the editorial process, Development now publishes a ‘Peer review history file’ alongside published papers. Read more about the policy and see the reports for yourself in one the first papers to publish the reports (under the ‘Info & metrics’ tab).

Development at a glance — Cell interactions in collective cell migration

Extract from the poster showing specific cell-cell interactions in metastasis.

Take a look at the latest poster and accompanying article by Denise Montell and her colleagues from the University of California, where they describe a sampling of both known and new cells that migrate collectively in vivo.
