Staging of gastrulating mouse embryos by morphological landmarks in the dissecting microscope
K.M. Downs, T. Davies
Development 1993 118: 1255-1266;

Summary

We describe and illustrate a set of morphological landmarks for classifying mouse embryos by gross morphology from before gastrulation to the beginning of organogenesis. These landmarks are visible at the resolution of the dissecting microscope in embryos that are intact except for reflexion of Reichert's membrane. Adoption of these criteria should facilitate interpretation of both the expression patterns of genes and the consequences of experimental manipulation of embryos during early postimplantation development.

An interview with Swathi Arur

Swathi Arur joined the team at Development as an Academic Editor in 2020. Her lab uses multidisciplinary approaches to understand female germline development and fertility. We met with her over Zoom to hear more about her life, her career and her love for C. elegans.

Jim Wells and Hanna Mikkola join our team of Editors

We are pleased to welcome James (Jim) Wells and Hanna Mikkola to our team of Editors. Jim joins us a new Academic Editor, taking over from Gordan Keller, and Hanna joins our team of Associate Editors. Find out more about their research interests and areas of expertise.

New funding scheme supports sustainable events

As part of our Sustainable Conferencing Initiative, we are pleased to announce funding for organisers that seek to reduce the environmental footprint of their event. The next deadline to apply for a Scientific Meeting grant is 26 March 2021.

Read & Publish participation continues to grow

“I’d heard of Read & Publish deals and knew that many universities, including mine, had signed up to them but I had not previously understood the benefits that these deals bring to authors who work at those universities.”

Professor Sally Lowell (University of Edinburgh) shares her experience of publishing Open Access as part of our growing Read & Publish initiative. We now have over 150 institutions in 15 countries and four library consortia taking part – find out more and view our full list of participating institutions.

Upcoming special issues

Imaging Development, Stem Cells and Regeneration
Submission deadline: 30 March 2021
Publication: mid-2021

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

Both special issues welcome Review articles as well as Research articles, and will be widely promoted online and at key global conferences.

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, Brandon Carpenter talks about how inherited histone methylation defines the germline versus soma decision in C. elegans.
