I’m happy to share our new preprint on stem cell regeneration in the human colon! Using new CRISPR knockins in organoids, we show that after stem cell loss, non-stem cells rapidly regenerate them. This process is normally inhibited by the stem cells themselves. Manuscript link: tinyurl.com/3ky4ccxf

Paper alert! β-catenin forms condensates that help build cell–cell adhesions - showing its role goes beyond simply linking E-cadherin to α-cat/actin. Great collaboration with the Schuijers lab! 👉 nature.com/articles/s41...

How do #stemcells integrate information to coordinate fate decisions? Delighted to finally see our work showing how growth factors regulate the mechano-osmotic state of the #nucleus and #chromatin to control #pluripotency exit out! www.nature.com/articles/s41... see 🧵 👇

Mechano-osmotic signals control chromatin state and fate transitions in pluripotent stem cells - Nature Cell Biology
McCreery, Stubb et al. show that mechano-osmotic changes in the nucleus induce general transcriptional repression and prime chromatin for cell fate transitions by relieving repression of specific differentiation genes.

A bit delayed, but excited to still share our latest paper, showing that intercellular forces transduced by E-cadherin activate EGFR-ERK signaling in epithelia by inducing EGFR ligand shedding! Mechanical and biochemical signals can act together within a single, linear cascade! tinyurl.com/mr9mj9j2

On cell extrusion in the #intestine! After 80 years of observations, we finally took a deeper look thanks to 2D #organoids. We report: 3D #forces, #extrusion still only in the villus even without curvature, #lamellipodia generate 3D force.. and more. Have a look! www.biorxiv.org/content/10.1...
