Very excited to see the first Beisaw lab publication out in its final form 🥳🥳 rdcu.be/ei1I7 if you’re interested in zebrafish heart regeneration and how cardiomyocytes replace the fibrotic injured tissue (spoiler alert: macrophages play an important role), then read it here 👇
Border-zone cardiomyocytes and macrophages regulate extracellular matrix remodeling to promote cardiomyocyte protrusion during cardiac regeneration
Nature Communications - Adult zebrafish are capable of heart regeneration, but how the collagenous injury site is replaced remains unclear. Here they provide an in-depth analysis of cardiomyocyte...

Everyone might need to update medaka from “non-regenerative” to “slightly less-regenerative” 😬 New work from @nadiamercader.bsky.social et al. 🐟🫀 #zebrafish #medaka

How does regeneration begin after heart injury?

In a new Nature Communications paper, the Junker lab at MDC/BIMSB uses in vivo single-cell RNA metabolic labeling to identify early transcriptional responders in the regenerating zebrafish heart.

In vivo single-cell RNA metabolic labeling resolves early transcriptional responders in the regenerating zebrafish heart - Nature Communications
This study maps the immediate transcriptional response after zebrafish heart injury and shows that fine-tuning early immune signals can further improve regeneration.

I am happy and excited to share our latest preprint on PLN cardiomyopathy:
www.biorxiv.org/cgi/content/...

We found that PLN R14del cardiomyocytes have lysosomal dysfunction resulting in PLN accumulation, microtubule remodelling and structural defects, which are rescued by lysosomal reactivation.
PLN accumulates in aged PLN R14del zebrafish hearts, which is resolved by fasting-induced lysosomal activation

Want to live in a quaint German town & work w/ #zebrafish toxicology models? Openings in Gölz Lab in Heidelberg!

PhD student: www.bioquant.uni-heidelberg.de/sites/defaul...
Technical asst: www.bioquant.uni-heidelberg.de/sites/defaul...

Learn about lab: www.bioquant.uni-heidelberg.de/groups/golz 🧪
The Gölz Lab investigates how environmental chemicals—including per- and polyfluoroalkyl substances (PFAS)—perturb intracellular signaling networks and how these early molecular events propagate across biological scales to drive functional tissue changes and organismal phenotypes. Guided by a One Health perspective, we connect environmental exposure to mechanistic pathways relevant for human and ecosystem health. We integrate human iPSC-derived 2D systems, such as advanced 3D organoid models, and zebrafish embryo assays to dissect conserved pathways and derive mechanistic, dose-resolved effect chains.

If you’re applying to your dream lab for an internship/PhD/postdoc, always send a second email 1-2 weeks after the first one if you don’t hear back.

I promise we will be grateful rather than annoyed. My email inbox is a disaster and I’m quite junior - and very few of us have secretarial support

Do zebrafish regenerate their hearts equally? In our new paper at the @tillymommersteeg.bsky.social lab we uncovered variations in the regenerative response of 7 wt zebrafish strains leading us to identify a critical role of oxidative phosphorylation in long-term heart regeneration.
