Modelling co-development between the somites and neural tube in human trunk-like structures - Nature Cell Biology Makwana, Tilley et al. generate human stem cell-based trunk-like structures approximating Carnegie stage 13–14 of development. They use them to model and study the development of the thoracic and lumbar trunk.

Lovely little pre-Christmas present to see this out @natcellbio.nature.com! Some 🔥 new results in here since the biorvix incl (1) a new RARE-GFP reporter ✳️🙌, (2) additional NMP quantification 🔢, (3) no neural tube patterning on RA inhibition 🙅 etc. Enjoy! 😍 www.nature.com/articles/s41...

NDiff227 gastruloids display a developmental delay in comparison to HM-N2B27 gastruloids. (A) Quantitative analysis of the roundness (perimeter2/4π×area⁠) of gastruloids cultured in either HM-N2B27 or NDiff227 showed that HM-N2B27 gastruloids are significantly less ‘Round’ than their NDiff227 counterparts at 96 h [unpaired two-tailed t-test; t(4)=−4.9541, P=0.008]. Each datapoint is the average roundness of an independent replicate experiment containing between ∼40 and 90 individual gastruloids (see Fig. S4B). (B) The frequency of morphologies from the data in A, with examples of gastruloids that would fall in each category (bottom; the left 'Protrusions' image is also shown in Fig. S4). (C) Light-sheet representative images (maximum projection images) highlighting the expression patterns of Cdh1 (magenta) and Cdh2 (cyan) between HM-N2B27 gastruloids at 96 h and NDiff227 gastruloids at 90 h and 96 h. Gastruloids developed in HM-N2B27 have upregulated Cdh2 by 90 h, unlike NDiff227 gastruloids, which show enhanced Cdh2 only at 96 h. Scale bars: 100 μm. (Ci) Qualitative analysis of the average expression pattern of Cdh2 (N-cadherin). The expression patterns were grouped into two categories (phenotypes I and II) and represent the average of three independent replicate experiments, each containing at least seven individual gastruloids per condition. Examples of the two categories are shown below. The leftmost example for ‘Phenotype I’ is shown in the middle row of 90 h HM-N2B27 (Cdh2) in C. For the box and whisker plot, the central line in the box is the median, the lower edge of the box is the first quartile, the upper edge of the box is the third quartile, and the box height is the IQR. The lower and upper whiskers indicate the smallest datapoint within 1.5xIQR below Q1 or above Q3, respectively.

I do like the @dev-journal.bsky.social "Research Report" format for shortish papers

This one is valuable. "Is it the N2B27?" is the stem cell biologist version of "Is it the magnesium?"

We've just updated our manuscript to a more 'publishable' version!
www.biorxiv.org/content/10.1...
New details about the role of Wnt in suppressing neural differentiation and fostering a posterior epiblast state, and the temporal effect of Nodal signalling in driving mesendodermal fates

Great work from Alexandra and Sebastian et al showing how gastrulation is governed downstream of Wnt and Nodal. Two competing transcriptional modules - two opposing signalling activities - orchestrate the emergence of the mammalian body plan.
moving forward, together

Difficult to believe that such a community has emerged @ #gastruloids as a model system to explore many aspects of #DevBio. Great to see a room so full of people, curiosity and good Science @prbb.org @upf.edu Thank you to all that have made this possible & of course to the participants

There's increasing evidence that in organoid/embryoids conditions of cells at start of experiments is crucial/ determines outcome. Much to be learnt still. Taking advantage of mouse #gastruloids, two groups explore this here. Important work to calibrate the field www.biorxiv.org/content/10.1...
