 1/6 Extremely happy to share my PhD work is out on bioRxiv! We discovered that microtubules deform mitotic centrosomes. When we removed them, the SPD-5 scaffold became denser but didn't lose material. This suggests it's an elastically deformable solid! This only happens in mitosis.

#GEF25 the expansion microscopy community would benefit from high NA, long working distance water objectives. Who's working on these? What's out there?

Lately I've been only posting images of really interesting protist here, but something that many don't know is that most of my time i'm expanding 'boring' mammalian cells and that I love human centrioles. Don't tell me that they are not beautiful😍👁️

It’s truly inspiring to see how persistence, collaboration, and communication across disciplines can transform ambitious ideas into such impactful stories. Seven years, four interdisciplinary teams, and countless discussions later—this really shows the power of timing, teamwork, and shared vision!😍

Cells can form patterns within themselves just like embryos do. How? Connie Yan's new preprint shows how the anterior-posterior cytoskeleton pattern in Stentor is dictated by regionalized scaffolding proteins

Measuring properties of individual cells in relation to their neighbors in 3D tissues is challenging. @cellysally.bsky.social &co develop a computational toolkit to facilitate this, analyzing developmental patterning in mouse, chick & #Drosophila #embryo @plosbiology.org 🧪 plos.io/4lQMeNu

Patterning of cell identities in the posterior E8.5 mouse embryo. Co-expression of mesoderm marker TBXT (blue) and neural marker SOX2 (green) identifies cells in the neuromesodermal (NMP) progenitor region at the intersection of their respective gene expression gradients. TBX6 (red) marks paraxial mesoderm and also marks sporadic mesoderm-committed cells emerging within the NMP region. LAMINB1 (white) marks the nuclear envelope of all cells. Credit: Matthew French.
