New morphometric analysis tool developed by Lu et al. applied to skeletal muscle cross-sections of four different juvenile teleost fish species. Main finding: Mosaic hyperplasia, i.e., the addition of new myofibers in the deep myotome, is near-zero in the small Danionella but dramatically enhanced in the giant danio relative to the intermediate grower zebrafish, establishing this mode of hyperplasia as a main driver of skeletal muscle growth in differently sized fishes.

Beautiful work led by Yansong (Kevin) Lu on skeletal muscle growth in zebrafish, giant danio, Danionella cerebrum, and killifish. HCR, new image analysis tool, scRNA-seq, and CRISPR. New international collaborations between Uni Melbourne, NCVC/Osaka, Stanford & ARMI www.biorxiv.org/content/10.6...

We have a postdoc position available. Please forward to anyone who may be interested.

Congratulations, Hadeer 🥳

Injury-induced electrochemical coupling triggers organ growth Organ repair and growth rely on coupling tissue-wide membrane depolarization with intracellular proliferative signaling.

New paper alert!🤩Super proud that our story led by superstar postdocs @liujinghui.bsky.social and @nerlielisa.bsky.social is finally out! We found how electrical signals are key for promoting organ regenerative growth!!! A thread 🧵https://www.science.org/doi/10.1126/sciadv.aec0687

If you are interested in a PhD on protein science in a very pretty part of Southern Germany, consider this amazing opportunity to work with @hadeerelhabashy.bsky.social.

Can we tune a plant’s epigenetic toolkit to disrupt plant homeostasis in ways that enable phenotypic innovation?

Amazing to see red blood cells moving through the gills! Don’t forget to check out the supplemental movies ;-)

***Super cool-project alert***⚠️ Come work with @dirkmetzler.bsky.social and me in trying to understand how transcriptional noise evolves in a phylogenetic context 🧬 Deadline 15th Dec 2025 (Project funded by @dfg.de @gevol.bsky.social)

Come join us in Heidelberg for the first German fish meeting 👩‍🔬👨‍🔬🧬🔬🐟🐠

How does messenger RNA (mRNA) get out of the nucleus to become a protein? Eukaryotic mRNA is packaged, exported, and then translated in the cytoplasm. But how do these steps work? And what are open questions? Check out our new review for our take: www.annualreviews.org/content/jour... (1/3)

Folks, it is finally out! Our paper on T2T assemblies of the zebrafish genome is on BioRxiv:

Insertion of an invading retrovirus regulates a novel color trait in swordtail fish For over a century, evolutionary biologists have been motivated to understand the mechanisms through which organisms adapt to their environments. Coloration and pigmentation are remarkably variable wi...

I am so excited to share new work on a TE insertion that regulates iridescence in swordtails, led by fantastic grad student @nadiahaghani.bsky.social and with help from many coauthors! In a time that has been so difficult to navigate, this & other projects have kept my spirits up: shorturl.at/NE65A

🔍 In our review, led by Tina Munch, a hydrocephalus neurosurgeon, we explore this question. We examined the role of cilia in human hydrocephalus and highlight a key insight: primary cilia may play a more critical role than motile cilia, particularly through their influence on brain development.

Dual transcriptional activities of PAX3 and PAX7 spatially encode spinal cell fates through distinct gene networks How do transcription factors, with pleotropic functions, generate organized cellular diversity in developing tissues? This study shows that PAX3 and PAX7 orchestrate spinal cord patterning by acting a...

Good to see this study from Ribes & co in print: PAX3/PAX7 transcription factors control neural tube patterning by simultaneously repressing ventral fates via H3K27me3 deposition at silencers & activating dorsal fates as pioneer factors at enhancers

The Question: We know the spinal cord has 11 molecularly distinct progenitor domains generating distinct neurons, but how are these linked by actual LINEAGE relationships? When do progenitors commit to specific cardinal neuron fates, and how early is that commitment resolved?

Thank you Leo. The labour of many people!

Cell-cell communication as underlying principle governing color pattern formation in fishes The diverse pigmentation patterns of animals are crucial for predation avoidance and behavioral display, yet mechanisms underlying this diversity remain poorly understood. In zebrafish, Turing models ...

Thank you to all involved labs, especially @dparichy.bsky.social for decades of passion for these species. Worth a read: cell-cell communication as underlying principle governing color pattern formation in fishes www.biorxiv.org/content/10.1... @zebrafishrock.bsky.social @mpi-bio-fml.bsky.social

Happy to have contributed to this big story. We present new genome assemblies, genus-wide complementation and allele-specific expression analyses in hybrids between zebrafish and closely related Danio species with divergent pigment patterns. A vertebrate model genus for basic comparative biology.
