Summary

The tissue polarity genes in Drosophila are required to coordinate cell polarity within the plane of the epidermis. Evidence to date suggests that these genes may encode components of a novel signal transduction pathway. Three of the genes, frizzled (fz), dishevelled (dsh), and prickle (pk) share a similar tissue polarity phenotype, suggesting that they function together in a single process. dsh is also known to function as a mediator of wingless (wg) signaling in a variety of developmental patterning processes in the fly. In this study, we make use of a fz transgene and a hypomorphic fz allele as genetic tools in an attempt to order these genes in a genetic hierarchy. Our results argue that dsh encodes a dosage sensitive component required for fz function and that it likely acts downstream of fz in the generation of tissue polarity. Our findings suggest that dsh may have a general role in signal transduction, perhaps as a component of a receptor complex.

A new society for regenerative biologists

Kenneth Poss and Elly Tanaka announce the launch of the International Society for Regenerative Biology (ISRB), which will promote research and education in the field of regenerative biology.

Upcoming special issue: call for papers

The Immune System in Development and Regeneration
Guest editors: Florent Ginhoux and Paul Martin
Submission deadline: 1 September 2021
Publication: Spring 2022

The special issue welcomes Review articles as well as Research articles, and will be widely promoted online and at key global conferences.

An interview with Cagney Coomer

Over a virtual chat, we spoke to Cagney Coomer about her experiences in the lab, the classroom and the community centre, and why she thinks outreach and role models are vital to science.

Development presents...

Our successful webinar series continues into 2021, with early-career researchers presenting their papers and a chance to virtually network with the developmental biology community afterwards. Here, Michèle Romanos talks about her new preprint, which mixes experimentation in quail embryos and computational modelling to understand how heterogeneity in a tissue influences cell rate.

Save your spot at our next session:

10 March
Time: 9:00 (GMT)
Chaired by: Thomas Lecuit
