Summary

The Drosophila doublesex (dsx) gene encodes a transcription factor that mediates sex determination. We describe the characterization of a novel zebrafish zinc-finger gene, terra, which contains a DNA binding domain similar to that of the Drosophila dsx gene. However, unlike dsx, terra is transiently expressed in the presomitic mesoderm and newly formed somites. Expression of terra in presomitic mesoderm is restricted to cells that lack expression of MyoD. In vivo, terra expression is reduced by hedgehog but enhanced by BMP signals. Overexpression of terra induces rapid apoptosis both in vitro and in vivo, suggesting that a tight regulation of terra expression is required during embryogenesis. Terra has both human and mouse homologs and is specifically expressed in mouse somites. Taken together, our findings suggest that terra is a highly conserved protein that plays specific roles in early somitogenesis of vertebrates.

The people behind the papers – George Britton and Aryeh Warmflash

George and Aryeh

First author George Britton and his supervisor Aryeh Warmflash discuss their new Development paper in which they apply advanced in vitro culturing techniques to investigate embryonic ectoderm patterning.


Travelling Fellowship – New imaging approach unveils a bigger picture

Highlights from Travelling Fellowship trips

Find out how Pamela Imperadore’s Travelling Fellowship grant from The Company of Biologists took her to Germany, where she used new imaging techniques to investigate the cellular machinery underlying octopus arm regeneration. Don’t miss the next application deadline for 2020 travel, coming up on 29 November. Where will your research take you?


Primer – Principles and applications of optogenetics in developmental biology

Schematic demonstrating the approaches to controlling protein activity using optogenetics.

Protein function can be controlled by light using optogenetic techniques. In their new Primer, Stefano De Renzis and his colleagues in Heidelberg provide an overview of the most commonly used optogenetic tools and their application in developmental biology.


preLights – Self-organised symmetry breaking in zebrafish reveals feedback from morphogenesis to pattern formation

Sundar Naganathan

preLighter Sundar Naganathan explains his selected preprint by Vikas Trivedi, Benjamin Steventon and their co-workers on pescoids, a new in vitro model system to study early zebrafish embryogenesis.


Spotlight – Can laboratory model systems instruct human limb regeneration?

An extract from a schematic demonstrating the possible pipeline for how discovery in lab model systems can influence applications for regenerative therapies.

One of the most challenging objectives of tissue regeneration research is regrowth of a lost or amputated limb. Here, Ben Cox, Maximina Yun and Kenneth Poss outline the research avenues yet to be explored to move closer to this capstone achievement.
