A quick re-intro: we are interested in the mechanisms of collective cell behaviour, particularly cell movement. We use fly embryos, quantitative microscopy, image analysis and computer-based modelling. One of the systems where we study collective cell movement is the wound healing response.

New preprint from the lab! We discovered a transient fluidization in the basal region of human forebrains by tracking microdroplets in cerebral organoids.This “basal fluidization”, absent in gorilla and mouse, may contribute to greater surface expansion in human forebrains

The 'sparks' of life! Our latest work on the role of #calcium dynamics in the early #embryo. 🎇🔬🐁

During #development, distal visceral #endoderm (DVE) cells migrate to shape A-P axis specification. @m-stower.bsky.social @srinivas-lab.bsky.social &co reveal the role of Ca2+ dynamics in this, showing that inhibition of #calcium transients causes DVE arrest @plosbiology.org 🧪 plos.io/4nHWxF4
Epiblast Ca2+ waves propagate from the apical to basal domain. The images show selected time points from movies of E5.5 GCaMP6f embryos imaged using a ZEISS lattice light-sheet 7 microscope. Top row: An example of an epiblast wave involving a large proportion of the tissue captured by imaging a volume of the embryo at 20-s intervals. A total of 9/16 embryos showed at least one epiblast Ca2+ wave. Bottom row: Faster imaging at 5-s interval revealed that the Ca2+ wave in the epiblast can be preceded by a transient in a neighboring VE cell—this was observed in 5/19 events from 9 embryos (white arrowheads).

How does a “universal” transcription factor evolve to do species-specific jobs?
Our new preprint reveals how divergence in TBP’s domains shapes transcriptional specialization across eukaryotes.

Molecular determinants underlying functional divergence of TBP homologs
The TATA-box binding protein (TBP) is a highly conserved basal transcription factor and a core component of the pre-initiation complex (PIC) for all three eukaryotic RNA polymerases (RNA Pols). Despit...

We present multi-immersion Oblique Plane microscope (miOPM), a light-sheet platform that can be adapted to a wide range of applications, from sensitive live cell imaging to imaging organs and cleared tissues.

High levels of Cas9 are toxic in sensory neurons. Reducing Cas9 levels with uORFs avoids toxicity and is compatible with efficient editing. From @thompsonpeerlab.bsky.social. Fly lines @vdrc-flies.bsky.social

I’m happy to share some plugins I’ve been developping this summer: "Channels and Contrast" and LUTs Manager!
I can’t find new bugs and ideas by now so I need your help to please test them in your machines and report bugs, feedbacks and ideas! forum.image.sc/t/looking-fo...

Modifying mechanical constraint guides gastruloid patterning

This Research Highlight showcases the work from Judith Pineau @judithpineau.bsky.social, Jerome Wong-Ng @jeromewongng.bsky.social, Thomas Gregor @thomasgregor.bsky.social and colleagues:

journals.biologists.com/dev/article/...
Figure 2 - Gene expression patterning and transcriptional profiles in hydrogel-grown gastruloids. (A) Representative immunofluorescence images of gastruloids at 120 h. Gastruloids were grown in standard culture conditions (Ctrl, no hydrogel) or embedded in hydrogels with increasing concentrations (0.7 mM, 0.8 mM and 1.0 mM) at 96 h post-seeding. Nuclei (blue), BRA (purple) and SOX2 (yellow) are labeled. (B,C) Normalized expression profiles of SOX2 (B) and BRA (C) along the AP axis, demonstrating consistent expression patterns across conditions. (D) Principal component analysis of bulk RNA-seq experiments (three replicates), revealing clear separation between Ctrl and noCHI (red), a negative control for gastruloid formation, while hydrogel-embedded conditions cluster near Ctrl. (E) Number of significantly differentially expressed (DE) genes compared to Ctrl, showing substantial transcriptional changes in noCHI and minimal changes in hydrogel-embedded conditions (0.7 mM, 0.8 mM and 1.0 mM). Shown here are representative data and analysis for one experimental replicate. See Fig. S3 for two additional replicates.

Sherif Khodeer and I discuss how stem cell-based embryo models provide evidence that viral DNA sequences that entered the human genome in the past were repurposed to aid early stages of embryonic development.

This work is a proof of concept towards fully programmable chromatin, something I think will become very common. By combining evolutionary insights, high-throughput assays and predictive/generative modeling, we should be able to uncover some true “superpowers” of chromatin (more on this soon!) 7/9
