Mesmerizing light sheet imaging of neutrophils swarming at a yeast target!
The neutrophils were labeled with SPY650-DNA (yellow) and a calcium dye (blue).

This movie is part of the recent manuscript by @strickland-evelyn.bsky.social that we highly recommend reading!

#zebrafish

Zebrafish finds Nemo. New paper with our great collaborators on gap junctional communication in widely divergent species.

👍 ctenophores are very cool!

Awesome! Congratulations! Though sad to be losing you from zebrafish 🙂🙁

It's out! Happy to present ITEC, a semi supervised algorithm with an extremely low error rate that can track cells in files of any size (think Terabytes!). We used it in many organisms, including zebrafish, to study how organs form and linked it to gene expression www.biorxiv.org/content/10.6... +🧪

Awesome 🤩 congratulations!!!

#zebrafish

Zebrafish larva imaged with scanning electron microscopy at 4 days post-fertilisation following exposure to 10 µM elafibranor. Affected surface periderm cells are dysmorphic, with reduced surface area due to increased apical constriction. These results provide new insights linking compromised skin barrier integrity to alterations in midface morphogenesis. See article by Molteni et al. (dmm052649).

Excited to have started my new lab in Human Genetics at Pitt Public Health!

We study wound healing in diabetes & aging using adult zebrafish. Check out this movie showing neutrophil dynamics after injury.

Now recruiting research staff, grad students, and postdocs. DM me if interested.

Not something you see in textbooks very often: tripolar mitosis.

An intracellular meteor shower. EB3 comets tracking growing microtubule plus-ends in a cultured cell.

Job alert! 📣 I’m looking for a research assistant to join my new team @idrm.ox.ac.uk

Were using #zebrafish to understand gene-environment interactions that shape the heart 🫀generate natural diversity 🐸🐭 and contribute to congenital defects ❤️‍🩹

Maximum intensity projection showing dorsal vasculature of the first gill arch of a CUBIC-cleared adult kdrl:mCherry zebrafish. Fluorescent signal was pseudocoloured using the PBIYC lookup table in ImageJ. Analysis of this endothelial reporter enabled detailed mapping of gill vascular development and revealed distinct medial and lateral filament types. Credit text to the journal Development.

Microscopy image of a developing mouse lung. Cells that express Shh are shown in green. Membranes of non-expressing cells are magenta.

Happy #FluorescenceFriday! I've shared this before but am reposting b/c I think the developing #lung is just so darn pretty! This is an E18.5 🐭 lung with 🟢 marking cells that express my favorite gene, Shh.🟣 marks cell membranes. 🔬 by @stjuderesearch.bsky.social postdoc👩‍🔬 @christinaadaly.bsky.social 🧪

This movie shows lysosomes (orange) and keratin (gray) in a cultured cell over 10 minutes.

I am proud to have contributed to this project during the first part of my postbaccalaureate fellowship, and excited to spend the rest of my time in this lab further investigating this structure.

We can now properly credit to @swinburnelab.bsky.social 🤩 Welcome to Bluesky! 🧪

Thanks Mathieu! We enjoyed your gill development paper, very nice work! and congratulations on the cover 🎉

Thanks Jason! 😊

Yup, they do.

Thanks 😊

Thanks Kevin! That’s very kind. 😊
