Neurogenesis, as turns out, is highly dependent on cytokine signalings. Even more interesting, the landscape of cytokines in the CNS is highly localised, and a large proportion of cytokine production is done by the meninges. This review by Rua et al discusses in more detail: doi.org/10.1016/j.cd...

I found this immune cell (🔴) prying open the junction between the ectoderm cells from underneath. You can see its protrusions probing (yellow arrow) and threading through between the other cells before the whole cell body is squeezed through in 1 sweeping motion. So cool! #FluorescenceFriday

An incredibly complicated process and incredibly crucial!

The importance of epigenetic modifications in embryonic development has been cemented. In mammals, the trophoblasts play a crucial role in implantation, and their DNA methylation status is crucial. This detailed review by Hua Zhang et al discussed just how important this is: doi.org/10.1016/j.cd...

Big congrats to Dr. Len Zon for being awarded the 2026 @marchofdimes.org Richard B Johnston Jr, MD Prize for his work in #devbio. His pioneering research has illuminated how blood develops in embryos, leading to a deeper understanding of genetic blood diseases. www.marchofdimes.org/about/news/r... 🧪

Cells moving through tissue interact with the ECM and also with other cells, which can affect morphogenesis. In this interesting paper from the M Lisa Manning lab, Kupffer's Vesicle's trailing cells are shaped by the dragging force from other cells as it moves through tissue. doi.org/10.1016/j.cd...

How can cells use information from neighboring cells to improve the spatial precision of morphogen patterns? 🤔 We show that cells can gain positional information by "talking" to their neighbors - how much depends critically on spatial correlations of the patterns. buff.ly/w56OUJT

Special issue announced, for those interested ✨

🎇 Calling for paper submission to our Special issue "Tissue Biology – at the interface between immunology and developmental biology". This issue focuses on the interactions between resident immune cells and the surrounding tissue. Deadline: ‼️30th March 2026‼️ www.sciencedirect.com/special-issu...

Animal caps are the original organoid!

A fascinating review on the role of Activin in organ induction. Isn't it wild that in Xenopus embryos, a piece of the animal cap can be induced with Activin at different concentrations and buffers to form the ❤️, kidney, the pancreas, head, tail, and even a whole embryoid 🤯: doi.org/10.1016/j.cd...

Make your gene knockouts more efficient with multiplexed Cas12a sgRNAs. Our new paper is out now, with tools available from @addgene.bsky.social , www.plasmids.eu and @vdrc-flies.bsky.social. www.nature.com/articles/s41... #CRISPR #geneediting #Drosophila 🧪🧬✂️🔬🪰 Summary 🧵 below.

So proud to share my paper on collective chemotaxis and force coordination in epithelial and mesenchymal cells, developed in the Mayor Lab and now published in JCB. Deeply grateful for everything I learned from Xenopus NC and the amphibian world, where adaptation is everything🐸

A new paper published in @jcb.org by postdoc Jorge Diaz from the Mayor lab at UCL shows that during collective migration, epithelial-like clusters generate traction force mainly through cryptic protrusions at the centre, while mesenchymal clusters do so at their periphery: doi.org/10.1083/jcb....

Did you know that melanocytes, chondrocytes, and even osteoblasts can be differentiated from Schwann Cell Precursors? These cells don't only give rise to Schwann cells as the name suggests but many other cell types. Check out this interesting review by Marianne Bronner et al: doi.org/10.1016/j.cd...

2-head frogs? 😲

A very curious paper from the De Robertis lab shows how Cerberus - a growth factor that inhibits Wnt signalling, and IGF - a growth factor that activates MAPK signalling, can synergistically induce a new head (aka ectopic archencephalic differentiation) in Xenopus embryos. doi.org/10.1016/j.cd...

Predicting cell state in previously unseen conditions has typically required retraining for each new biological context. Today, Arc is releasing Stack, a foundation model that learns to simulate cell state under novel conditions directly at inference time, no fine-tuning required.

Microscopy Bat signal! I want to compile a list of biological samples that demonstrate microscope capabilities, including the reagents to generate them. Please send me anything you know of!! Beads are great for QC, but there's a different teaching benefit with biology. 1/n
