📢 The #Danioheart atlas webpage has been updated.
In addition to the whole dataset (>34,000 zebrafish heart cells across 10 developmental stages) we now provide subclusters of each major cardiac cell population. #zebrafish #heart #scRNAseq

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.

The pericardium forms as a distinct structure during heart formation - Nature Communications

The developing heart integrates several progenitor cell types. Here they show that the pericardium enveloping the heart develops among cells that form the mesothelium around inner organs and body cavities, distinct from the classic heart field.

Ventricle position can be remodeled after heart looping!
In a model of heterotaxy we uncovered a new asymmetric morphogenesis process during which the heart reorients its chambers.
So grateful to all the authors for their expertise and input during this long (but fun) ride 💪

MFer COOKED here

What’s a surprising question that you are asked about your job?
People often ask us to justify why we do our work or explain its broader benefit to society. I often retort with: “No one asks an accountant, or someone making money from money, what their greater purpose is.” Yet, someone like me working to conserve frogs is treated as if that’s not a real job. I’m not tired of justifying that what I do is important, because we are saving species from the face of extinction. But I do enjoy making people laugh with that joke, because it’s true.
