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 ❤️‍🩹

Full info below, and please share! 🫶🏻

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! 🧪

JCS Cover: Cyri-b-knockout Cos-7 cells spread wide with actin-driven lamellipodia (blue), while microtubules (orange) do not always reach the cell edge, capturing the dynamic interplay of cytoskeletal systems. See article by J. A. Whitelaw et al. (jcs263646).

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. 😊

Thanks Philipp!

Exciting new #Zebrafish research from the #WeinsteinLab, led by Jong Park!

Amazing to see red blood cells moving through the gills! Don’t forget to check out the supplemental movies ;-)

Zebrafish are an excellent model for studying the development and function of blood and lymphatic vessels. Research in zebrafish has even led to treatments for lymphatic disorders in people. This image, taken using a powerful microscope that uses lasers to illuminate the fish, shows blood vessels (magenta) and lymphatic vessels (green) in the eye and head of an anesthetized, 6-week-old, transgenic zebrafish.

#KnowYourZDM: In 2019, a 10-year-old patient w/ a life-threatening lymphatic disorder was losing hope. Zebrafish to the rescue! Scientists created zebrafish with the same gene mutation and found a melanoma drug that fixed the fish. Then, doctors used the same drug on the patient to save his life! 🧪

Our work out in @devbiol.bsky.social, PDGFra is needed for 🧠 perivascular fibroblast development... ⬇️ perivascular fibroblast = ⬇️ perivascular macrophage...cross-talk? 👀
Led by Hannah Jones @hejcell.bsky.social w/ Kelsey Abrams, Sophia Kim, excited for more projects w/ @fantauzzolab.bsky.social!

Check out our recent preprint, "Live longitudinal imaging of meningeal cerebrovascular injury and its sequelae in adult zebrafish."

Live longitudinal imaging of meningeal cerebrovascular injury and its sequelae in adult zebrafish https://www.biorxiv.org/content/10.1101/2025.11.14.688311v1

“By performing longitudinal live imaging of intubated adult fish we observe vascular regrowth and immune responses to [meningeal cerebrovascular injuries] over time in the same animal with unprecedented resolution”

New work from #WeinsteinLab at NIH

Image of an adult zebrafish using discarded film slides. There are stripes of dark brown and blue capturing the essence of adult zebrafish

#ZebrafishFunFacts: Using the discarded slide film from his doctoral research, Professor and amateur artist Michael Barresi created a mosaic of an adult #zebrafish.

MDI Bio Lab’s Hannah Somers’ Image Wins International Recognition

Big congratulations to Hannah Somers, Digital Image Analyst at MDI Bio Lab, whose striking visualization of a zebrafish’s brain was named an Image of Distinction in the Nikon Small World competition — and featured by #NationalGeographic!
