A single morphogenetic field gives rise to two retina primordia under the influence of the prechordal plate

Summary

Two bilaterally symmetric eyes arise from the anterior neural plate in vertebrate embryos. An interesting question is whether both eyes share a common developmental origin or they originate separately. We report here that the expression pattern of a new gene ET reveals that there is a single retina field which resolves into two separate primordia, a suggestion supported by the expression pattern of the Xenopus Pax-6 gene. Lineage tracing experiments demonstrate that retina field resolution is not due to migration of cells in the median region to the lateral parts of the field. Removal of the prechordal mesoderm led to formation of a single retina both in chick embryos and in Xenopus explants. Transplantation experiments in chick embryos indicate that the prechordal plate is able to suppress Pax-6 expression. Our results provide direct evidence for the existence of a single retina field, indicate that the retina field is resolved by suppression of retina formation in the median region of the field, and demonstrate that the prechordal plate plays a primary signaling role in retina field resolution.

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
