#MicroscopyMonday featuring gastric metaplasia. Extracellular matrix staining is purple, enteroendocrine cells are yellow, and mucus cells are teal.

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 🧪

A confocal microscopy image showing early tau accumulation in the brain with Alzheimer's Disease. Everything in blue (all nuclei) and green (neurons) is healthy. All the other colors are composed of a combination of different markers for pathological tau. The key question is: how do we avoid this tau spreading from cell to cell via neuronal connections? If we can avoid this, we can avoid memory loss.

Guess you can use a timeline cleanser? Can I show you some microscopy? My job is to see beauty even in sad things (so we can learn how to prevent them!). This is a brain with early Alzheimer's. This image was acquired in 3D and took 72 hours to get ready!

Different small intestinal cell types for #FluorescenceFriday

#TuftTuesday featuring some interesting tuft cell (pink) morphologies.

#MicroscopyMonday

Happy #FluorescenceFriday from some small intestinal villi.

So many tuft cells (yellow/orange) for #TuftTuesday. Immune cells are in green.

Some intestinal mucus staining (green) for #MicroscopyMonday

Happy #FluorescenceFriday!

Thanks! My lab does our own sectioning. It saves a ton of money and gives us some control over our samples.

The first gland at the stomach’s limiting ridge is packed with tuft cells #TuftTuesday

A modified H&E for #MicroscopyMonday

The first image I took of 2026 #FluorescentFriday

First #MicroscopyMonday of 2026 deserves some festive cells.

Hoping everyone's new year fluorescence is clear and bright. Happy #FluorescenceFriday.

#GESRC GI Epithelium Meeting is wrapping up today. A great conference full of great research.

Enjoying #GESRC, so many good talks and a lot of interesting research on GI tuft cells #TuftTuesday

Great question, it could use some neon tiger print to make it more Lisa Frank 🙂

Some tuft cells for #TuftTuesday

Is this too Lisa Frank for a journal cover? #MicroscopyMonday

That’s such a good hashtag!

#TuftTuesday

Thanks! It’s just one set of antibodies. I can add up to four plus DAPI.

Goodbye June #MicroscopyMonday

Every week feels a bit longer, glad that it is finally #FluorescenceFriday. Mouse liver tissue featuring a lot of diploid cells.

A Boa Constrictor brain-derived cell expressing a viral glycoprotein (magenta) and stained for actin (yellow) and DNA (white).

Another #MicroscopyMonday featuring small intestinal cells

Happy Birthday! Wishing you all the best.
