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.

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

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.

#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! 🧪
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.

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!
Micrscopy images of cleared cerebral brain tissue showing penetrating blood vessels (white) in mice - magenta cells are perivascular fibroblasts and cyan cells are perivascular macrophages - in control mice, both cell types are near the vessel termini by postnatal day 10 but in 'cKO' mice that lack expression of a tyrosine kinase receptor PDGFRa in fibroblasts, both the fibroblasts and macrophages are only partially covering the vessels.

#KnowYourZDM: Humans and #zebrafish carrying mutations in VEGFC or its receptor (FLT4) have defects in the formation of their lymphatic systems, which are important for draining lymph back into the circulation system.  As a result, these individuals display severe #lymphedema. 🧪
Humans bearing mutations in vascular endothelial growth factor C (VEGFC) or its receptor tyrosine kinase (FLT4) have defects in the formation of their lymphatic system, which is important for draining interstitial fluid back into the circulatory system. As a consequence, these patients display severe lymphedema (bottom left). In zebrafish, we have generated mutations in vegfc and flt4, both of which are conserved between zebrafish and humans. Like humans, zebrafish larvae also display lymphedema due to a failure to form a complete lymphatic system (bottom right).
