Segment polarity genes are expressed and required in restricted domains within each metameric unit of the Drosophila embryo. We have used the expression of two segment polarity genes engrailed (en) and wingless (wg) to monitor the effects of segment polarity mutants on the basic metameric pattern. Absence of patched (ptc) or naked (nkd) functions triggers a novel sequence of en and wg patterns. In addition, although wg and en are not expressed on the same cells absence of either one has effects on the expression of the other. These observations, together with an analysis of mutant phenotypes during development, lead us to suggest that positional information is encoded in cell states defined and maintained by the activity of segment polarity gene products.
Development Journal Meeting 2022: From Stem Cells to Human Development
-JournalMeeting.png?versionId=3737)
Following a virtual meeting in 2020, we are delighted to announce that the fifth iteration of our popular Journal Meeting will be held from 11-14 September 2022 at the historic Wotton House, Surrey. Registration is open now.
Special Issue: The Immune System in Development and Regeneration
(update)-ImmuneSI.png?versionId=3737)
Our latest special issue is now complete. It showcases articles that add to the repertoire of immune cell functions during development, repair and regeneration, and provide insights into the developmental pathways leading to the generation and dispersal of these cells.
Propose a new Workshop
-GSWorkshop.png?versionId=3737)
Our Workshops bring together leading experts and early-career researchers from a range of scientific backgrounds. Applications are now open to propose Workshops for 2024, one of which will be held in a Global South country.
Preprints in Development
(update)-InPreprints.png?versionId=3737)
As part of our efforts to support the use of preprints and help curate the preprint literature, we are delighted to launch a new article type: ‘In preprints’. These pieces will discuss one or more recent preprints and place them in a broader context. You can read the first article here.
FocalPlane Network launched
-FocalPlaneNetworkLaunch.png?versionId=3737)
Like the Node Network, the aim of the FocalPlane Network is to facilitate promotion and networking as well as assist those seeking conference speakers, committee members, reviewers or collaborators. We hope that it will help promote diversity in the community. Find out more and join the Network here.
