Very pleased to finally share the main story from my PhD, now published in @natcomms.nature.com ! 🎉 Using a sea anemone we discovered and characterised epithelial cell extrusion as the mechanism underlying starvation-induced cell loss. 🔗 Open-access article: www.nature.com/articles/s41...

Epithelial cell extrusion underlies starvation-induced cell loss in a sea anemone - Nature Communications

Epithelial cell extrusion in a sea anemone shares key hallmarks with bilaterians and is dynamically regulated by nutritional status. During starvation-induced body shrinkage, extrusion likely contribu...

In a new (ish) preprint, we used CRISPR barcodes to label germline stem cell clones in zebrafish, then tracked their contributions to sperm production for 2 years. Instead of staying stable, individual clones rose, fell, and disappeared over time. www.biorxiv.org/content/10.6...

Clonal dynamics deviate from neutral drift in zebrafish spermatogenesis

Spermatogonial stem cells (SSCs) maintain male fertility, but how their clonal dynamics change with age remains poorly understood. Here, we use in vivo CRISPR barcoding in zebrafish to label SSCs and ...
