What is going on with these zebrafish basal skin cells? I invite you to a šŸ§µ on wound healing, hydraulic fracking, and macropinocytosis, from subcellular to tissue-scale! All part of my favorite PhD project, now up on bioRxiv (1/17)

biorxiv.org/content/10.110ā€¦ This was a fantastic collaboration with co-first author @SatheMugdha (dextran and endosome obsessed), along with @EllenLabuz and Chris Prinz (professional fish stabbers). Being part of the Theriot lab zebrafish crew was such a joy! (2/17) 4 people (Team Zebrafish) eating food and facing the camera.

The 1st paper from my thesis is up on @biorXivpreprint!

Main question: how do skin cells know when (and where) injury has occurred nearby?

A šŸ§µ about how #zebrafish embryos sense wounds via osmotic AND electric cues, with plenty of cool movies! (1/12)

biorxiv.org/content/10.110ā€¦ šŸ¦“šŸŸ skin cells respond to wounds FAST: within seconds after injury, cells 100s of microns away start reacting. How do they know so quickly?

(Most movies in this šŸ§µ are of LifeAct-GFP in the basal cell layer of the embryonic tailfin, reacting to a wound to the right.) (2/12)
