🧪 Wondering if HFSP Research Grants are the right fit for you?

You might be a good match if your idea is:
🔹 Too bold or risky for traditional funders
🔹 Strongly interdisciplinary
🔹 Best tackled by an international team

Old school cell division data hand drawn by Wacław Mayzel while he looked through his microscope; circa 1884. #CellBiology

#Mastodon, the Command Center for Large-Scale Lineage-Tracing Microscopy Datasets, is finally heading for publication (well, let's see). To #cite or not to cite shall no longer be the question 🙃, because the #preprint. Software is available in every #Fiji near you.

Organelles do NOT have a single uniform pH.
And if you think they must, because “protons diffuse fast,” this paper is for you.
A thread on why that assumption is wrong; and what we found instead. 🧵 1/n

What would Santa Waclaw Mayzel give the good little boys and girls of the world?

Festive drawings of a cell dividing into two daughter cells of course!

In 1984, Drosophila homeotic genes were found to be conserved across animals, including humans 🧬🐸. This article highlights a shared genetic toolkit for embryonic development 🔬🌟🎁  doi.org/10.1016/j.yd...

📜We are thrilled to announce that the latest MorphoNet paper is officially published 🎉 ! Discover 5 varied use cases in which MorphoNet helps segment, curate, evaluate & validate complex 3D+t datasets, and much more 🧑‍💻 ! Read at @elife.bsky.social : doi.org/10.7554/eLif...

🚨 New preprint!
We built a single-cell atlas of 14 multilayered epithelia and revealed a conserved transcriptomic program guiding tissue architecture and fate composition. Our work brings decades of tissue-specific studies together into a unified evo-devo framework.

Above: transverse sections of neurulating chick embryos stained for DNA (methyl green) and F-actin (TRITC-phalloidin), without and with the addition of the phorbol ester PMA. Below: computational simulations of pseudostratified epithelia, with different apicobasal/lateral tension ratios. Either PMA treatment in embryos, or lower ratios in simulations, cause epithelial instability evidenced by extensive cell extrusion.

Paper alert! Mechanical conditions preventing live cell extrusion during primary neurulation in amniotes. @sabr-bio.bsky.social article published as pre-proof in @cellsdev.bsky.social! doi.org/10.1016/j.cd...

We just released a new major version of TrackMate (v8), the cell and organelle tracking plugin of Fiji.

It ships many new features, detailed below, but that are articulated around the following:

quick test with SAM3 - impressed with how well it seems to track long protrusions? prompted for "cell", does not find anything when looking for "fibroblast" or "nucleus"

Felix Zhou's u-Segment3D is out:

www.nature.com/articles/s41...

It leverages 2D cell segmentations from orthoviews to generate a ‘consensus’ 3D segmentation.

It does a great job on segmenting densely packed samples, and we have used the algorithm in many applications.

"His secret weapons were an unquenchable curiosity and continuing hands-on experimentation at the bench with his beautiful frog embryos and oocytes".

A thoughtful tribute to the life of Sir John Gurdon by Edward M. De Robertis that we really recommend everyone to read.

Just published! We share an open-source workflow to measure membrane thickness from tomograms, including a tutorial with 3D visualizations. We analyze thickness variations across organelles and reflect on where to define a membrane boundary. @becklab.bsky.social #teamtomo rupress.org/jcb/article/...
