Cholangiocytes contribute to hepatocyte regeneration after partial liver injury during growth spurt in zebrafish The liver's regenerative ability depends on injury extent. Minor injuries are repaired by hepatocyte self-duplication, while severe damage triggers cholangiocyte involvement in hepatocyte recovery. Th...

Excited to share our latest work on #liver #regeneration in @biorxiv-devbio.bsky.social ! We uncover how cholangiocytes contribute to hepatocyte regeneration, even in the presence of spared hepatocytes, using our novel CellCousin model in #zebrafish: www.biorxiv.org/content/10.1... 🐟✨ A 🧵👇 (1/12)

Spatial transcriptomic clocks reveal cell proximity effects in brain ageing Nature - A spatially resolved single-cell transcriptomics map of the mouse brain at different ages reveals signatures of ageing, rejuvenation and disease, including ageing effects associated with T...

Thrilled to see this paper out!! 🧪

Spatial transcriptomics of brain aging and 'spatial aging clocks' identify cells that have pro-aging or pro-rejuvenating effects on their neighbors!

Huge CONGRATS to Eric Sun and all authors! Fantastic collaboration with @jameszou.bsky.social!

How can some vertebrates naturally recover from deafness?

In work in PNAS, Tuo Shi finds that enhancers for sensory genes remain open but silent in sister cells of zebrafish and lizards, allowing these to make new inner ear sensory hair cells upon damage. www.pnas.org/doi/10.1073/...

Zebrafish glial-vascular interactions progressively expand over the course of brain development Glial-vascular interactions are critical for the formation and maintenance of brain blood vessels and the blood-brain barrier (BBB) in mammals, but their role in the zebrafish BBB remains unclear. Using three glial gene promoters—gfap, glast, and glastini (a truncated glast)—we explored glial-vascular development in zebrafish. Sparse labeling showed fewer glial-vascular interactions at early stages, with glial coverage and contact area increasing with age. Stable transgenic lines for glast and glastini revealed similar developmental increases, starting at ∼30% coverage at 3 days post-fertilization (dpf) and peaking at ∼60% by 10 dpf, and consistently higher glial coverage in the forebrain and midbrain than in the hindbrain.

And somehow I missed it going live last week 😂 - our #zebrafish glial-vascular paper is available for those finterested! One of the best ways to end 2024 as a #newPI www.cell.com/iscience/ful...

Congrats Caghan! Beautiful work!

Decoding the molecular, cellular, and functional heterogeneity of zebrafish intracardiac nervous system - Nature Communications Although the heart has its own nervous system, its organization and functionality remain largely unknown.

🚨 Our new study out in @natureportfolio.bsky.social! 🌟
We identify the "little brain" of the heart: the intricate intracardiac nervous system (IcNS) of zebrafish! 🐟

More about how this changes what we know about heart functionality.
