Hybrid female sterility due to cohesin protection errors in mouse oocytes Misregulation of chromosome cohesion during female meiosis serves as a reproductive isolating barrier in mice.

Another announcement! 📣 Our work on hybrid incompatibility in cohesin protection in 🐭oocytes is published!! Congrats Warif El Yakoubi and Eddie Pan!!🎉 We found hybrids with cohesion errors in two distinct genus.

To turn spatial data into a 3D object, check our protocol (open source, napari plug-in). @guignardlab.bsky.social @adrianobolondi.bsky.social @ibdm.bsky.social
For example, if you have spatial RNA-seq as sections, you can align them automatically to analyse directly in 3D.

Foxi1 regulates multipotent mucociliary progenitors and ionocyte specification through transcriptional and epigenetic mechanisms The transcription factor Foxi1 regulates ionocytes across species and organs and it is associated with several human diseases, but its function in epidermis remains unclear. This study shows that low ...

Good start for 2026: Our work on mucociliary progenitors and how FOXI1 regulates them as well as ionocyte specification is now out and open access.
