Best buddies? More like budding buddies 🪼👯‍♀️✨ Six stages of asexual budding in Hydra to generate new genetically identical individuals (clones). 🟣: collagen 🟢: stem cells. 📸 Image by Ben Cox #FluorescentFriday

First 24 hours of embryonic development in 9 different animal species: (From left to right) Zebrafish, Sea urchin, Black widow spider, Tardigrade, Sea squirt, Comb jelly, Parchment tube worm, Roundworm, Slipper snail.

Finally got the SIM perfectly calibrated on all four channels 🌈 (movie shows a 15x15 μm area inside a cell) #realtimemicroscopy

I found this immune cell (🔴) prying open the junction between the ectoderm cells from underneath. You can see its protrusions probing (yellow arrow) and threading through between the other cells before the whole cell body is squeezed through in 1 sweeping motion. So cool! #FluorescenceFriday

Hi thanks for sharing, I have one comment and two questions:
- this is super cool!
- what scope is it and why are cells so oily?
- what video format did you use to upload? It doesn't look too destroyed by compression

It’s #FluorescentFriday!

My fav so far 🤍🩶

Cellular study in black and white 🖤🤍

​I inverted the LUTs on these Mouse Embryonic Fibroblasts (MEF) to reveal the texture of the cytoskeleton.

​Proof that you don't always need neon to make a statement!

​🔬 @zeiss-microscopy.bsky.social LSM980 + Airyscan 2.

Excited to share this collaborative work with @sarathomasy.bsky.social- spearheaded by Raneesh Ramarapu and William Stoehr- where we visualized the unique spatial localization of tubulin isotopes in neural crest-derived corneal tissues during development. 🤩

Fluorescence Friday - DNA-PAINT imaging of axon initial segment TRIM46 ('cyan') and bIV spectrin ('red') by the incomparable Allison Melton in my laboratory. Just spectacular!

Cerebellar lobe of a mouse at postnatal day 10, with Purkinje neurons in white (stained for Calbindin expression) and granule cells fate-labeled in red (Cux2Cre activity).

I had the most amazing mortadella, pistachio, mascarpone, arugula sandwich, squeezed between two slices of fluffy focaccia for lunch. Didn’t last long enough for a pic. Thought I should share for no apparent reason.

Oh and here’s my #FluorescenceFriday image of a neonatal cerebellar lobe.

Happy #FluorescenceFriday! This micrograph of SHH-expressing cells in the developing 🐭 spinal cord are giving aurora borealis vibes 🌄. Notice the thin extensions reaching out from the cells at the top of the image - signaling protrusions! 🔬 by 👩‍🔬 @christinaadaly.bsky.social

This developing quail embryo looks like it's thinking fiery thoughts for #FluorescenceFriday 🐣🔥🧪. Imaged by the fantastic @vanderspuy.bsky.social

enjoy!

Really excited to share our new paper in @nature.com! We uncovered how a physical instability of the cytoplasm coupled with the cell cycle drives cytoplasmic partitioning in early embryos #zebrafish #drosophila. Read more in this🧵 www.nature.com/articles/s41... 🤩
