We study the heart and brain using zebrafish, focusing on the formation of blood and lymphatic vessels and their impact on tissue development and repair. labharrison.com

Vascular mural cells protect the adult brain from haemorrhage but do not control the blood-brain barrier in developing zebrafish The blood-brain barrier (BBB) protects the brain from circulating metabolites and plays central roles in neurological diseases. Endothelial cells (ECs) of the BBB are enwrapped by mural cells includin...

Just swam over to Bluesky and decided to dip my fin in the water. I am a Postdoc in the Weinstein lab and currently on the faculty job market. I developed an injury system to study cutaneous wound healing in adult zebrafish. Check out my movie showing neutrophil recruitment after injury.

Good question, we are trying to look at flow but certainly think after regeneration the "new" tissue is more highly perfused than before injury... during, not sure ๐Ÿค”

I used this in my Developmental Vascular Biology Lecture last week - really puts it in context in under 40 seconds - love it

How can we join the zebrafish slack? Sounds like a good idea

We have the myl7:CreER line

There don't seem to be hard and fast rules explaining why regenerative potential varies so much across species or between organs within species. Zebrafish are bony, but even relatively closely related species don't display the same regenerative capacity. The big question is how to turn it back on.

Watching coronary artery regeneration in zebrafish after resection of the heart apex. Zebrafish regenerative potential never ceases to amaze and inspire hope! Happy

Our debut here ๐Ÿฅฐ

Non-invasive intravital imaging of wound in skin epithelium of a juvenille zebrafish fed with a High-Cholesterol diet (HCD) versus a Normal Diet (ND)

Zebrafish is an outstanding model to study how diet and metabolic disease impact neutrophils
