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 ...

Thrilled to post thread re: new single-cell lineage of mouse embryo reconstructed w/ DNA Typewriter. One animal, zygote to late organogenesis (E13.5). Tree has 1,340,794 transcriptionally profiled, annotated tips (cells), 1,142,588 dated internal nodes, rooted at zygote 1/n

The 1996 Development issue reporting the zebrafish screen (and the special issue commemorating it 25 years later) are now free to read, thanks @biologists.bsky.social journals.biologists.com/dev/collecti...

In 2021, the journal Development published a special issue, “The Zebrafish Issue: 25 Years On.” Unfortunately, all the articles are behind a paywall. At the very least, special issues like this should be made open access. journals.biologists.com/dev/collecti...

It was an absolute JOY to be in Vienna to see my colleague David Grunwald be awarded the @izfs.bsky.social George Streisinger Award! David gave us an inspiring reminder of who we are as a community, how we got here, and what we can accomplish when we work together. #zebrafish #EZM2026

📣 Meeting announcement - the SDB Southwest Regional meeting will be at the University of Utah from March 5-7, 2027! Developmental biologists from Denver to Mexico City and from Reno to New Orleans, join us to share your research and celebrate our community. Details soon. @socdevbio.bsky.social

Spectacular preprint led by @sydsat.bsky.social in @ohnolog.bsky.social lab, @uwgenome.bsky.social. Neutrophils precede gastrulation in killifish and rapidly patrol the yolk. (1/2)

Early immune cell development precedes gastrulation in annual killifish

During embryogenesis, cell types arise in a predictable order because developmental regulators act sequentially. But how evolutionary changes in morphogenesis reshape the signaling environments that a...

(1/X) Assembling a time- and embryo-resolved sci-RNA-seq atlas of (slow) medaka development from blastula to hatch, we use comparative analysis of (fast) zebrafish to understand global + cell type-specific trends in developmental timing. Excited to get this resource out to the fish community!

Excited to share the published version of MIC-Drop-seq @natcomms.nature.com! Shoutout to co-lead authors @claycarey.bsky.social @sparvez.bsky.social for driving this work. Excited to see where this new scale of single-cell perturbation screening goes next. www.nature.com/articles/s41...

James Gagnon@james-gagnon.bsky.social · last yr.

To dissect the gene regulatory networks used to build organisms, we need Perturb-seq-like tools that work in whole animals. For this purpose, we developed MIC-Drop-seq, a tool that couples high-throughput CRISPR in zebrafish embryos with single-cell RNAseq. www.biorxiv.org/content/10.1...

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! 🧵👇
