So... Can be animals without #scutoids?
This a difficult question to answer, you cannot get mutants without scutoids.
So we designed a computational model to demonstrated that it is not possible to form epithelial tubes without apico-basal intercalations.

Two scutoids... a gran one and a yellow one. Graphical abstract of the paper. We infer Forces from geometry to find that scutoids are necessary to form epithelial tubes.

And now in english... We are very happy! In this interesting article of SCIENTIFIC AMERICAN, the #scutoids reach the status of a reference shape to tile the 3D space; being compared with the Kelvin structure. #SciComm

Guillaume Pernollet shows that epithelial cells adjust their shape to locally flatten, forming scutoids for any geometry, changing our view of cell packing. Thanks to all! @clairedessalles.bsky.social @juanmagararc.bsky.social @sciencesunige.bsky.social

Beautiful work from Rados et al.: if archaea are exposed to compressive forces, they form tissue-like structures...and guess what? Scutoids emerge!

(further evidence that "our" shape is a universal solution for efficient cell packing: scutoids rock! 🤓)

So, today the 10 year old got interested in scutoids due to a Vi Hart video, and that led to looking into all sorts of weird shapes, and HOLY SHIT how come nobody told me about trajectoids? www.youtube.com/watch?v=VbuX...

@lmescu.bsky.social and @javierbuceta.bsky.social discovered a new shape

How cool is that?!

WARNING!!!!!

In this issue you can find an amazing paper.

Our lab and @baronelab.bsky.social working together to investigate how 3D epithelial packing and growth are coupled during #SeaStar embryo development.

We find that #scutoids are the favorite shape of the cells after mitosis.

Cover: Development of transgenic Lytechinus pictus, the first transgenic echinoderm lines, expressing cyan fluorescent protein fused to a nuclear marker (histone 2B) driven by a polyubiquitin promoter. Developmental stages expressing the transgene are depicted from blastula (12 h post-fertilisation) through the larval stages, to the competent larva (22 days post-fertilisation), and finally to the juvenile stage at center. The juvenile has an additional membrane stain (grey) for contrast. See Research article by Jackson et al. (dev202991). Image credit: Svenja Kling, Yoon Lee and Elliot Jackson; Hamdoun Laboratory.

Tissue-like multicellular development triggered by mechanical compression in archaea
The advent of clonal multicellularity is a critical evolutionary milestone, seen often in eukaryotes, rarely in bacteria, and only once in archaea. We show that uniaxial compression induces clonal multicellularity in haloarchaea, forming tissue-like ...

We wondered: could a cell’s 3D shape affect its signalling range? Wing disc cells are scutoids, and therefore could meet new neighbours through apico-basal intercalations.
