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...

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.

Excited to share our preprint! We show that sustained macrophage and B cell responses are essential for heart regeneration in Mexican cavefish, helping uncover why surface fish heal but cavefish scar 🫀🐟. Check out the full story:

Absence of a prolonged macrophage and B cell response inhibits heart regeneration in the Mexican cavefish

A balanced immune response after cardiac injury is crucial to successful heart regeneration, but knowledge of what distinguishes a regenerative from a scarring response is still limited. The Mexican c...
