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 ...

Repost please !! We have extended the abstract deadline for the 2026 Santa Cruz Developmental Biology Conference to June 20. scdb2026.sites.ucsc.edu. Get those abstract in !

Do you know an outstanding aquarist? We're hiring a Senior Aquarist to help run our cephalopod facility at Columbia University. Our team maintains a colony of 250+ cuttlefish, develops new husbandry techniques (inc transgenics) & studies cuttlefish camouflage and social behavior. 1/3 [Pls repost!]

DEADLINE EXTENDED! There's still time to register for the Santa Cruz Developmental Biology Meeting! Great science, great people, big trees! Join us! scdb2026.sites.ucsc.edu

New insights into #fertilization from the @pauligroup.bsky.social & Ikawa labs! In a tour-de-force study, we discovered ✨ SPARK ✨, a conserved sperm fertilization complex that couples sperm-egg binding to membrane fusion. Read on 🧵👇 and check out our preprint for more details! tinyurl.com/34cm4xat

How do sperm and egg fuse? Surprisingly, we still don’t fully know… Our field has uncovered many pieces of the fertilization puzzle, but not how they fit together. We identify ✨ SPARK ✨ - a conserved sperm complex that couples sperm-egg binding to fusion. tinyurl.com/34cm4xat Read on! 🧵👇
