Stoked to share TWO preprints on mitochondrial pearling! 🎉 We uncover how spontaneous #mitochondria pearling drives #mtDNA nucleoid distribution (doi.org/10.1101/2024...), and @gavsturm.bsky.social et al. dissect the biophysics behind it (doi.org/10.1101/2024...). Details below! 🔬🧵🧪

After 7 years and a lot of memories, I've finally decided to retire Zebrafish Rock! on social media. I really want to say it was always positive but I've had a tumultuous experience with the account. Those that make the community more toxic continue to be promoted to positions of power. 1/4

MBL scientists use skates and their embryos to study skeletal development. By shining a light through egg cases, scientists can watch the entire maturation process. Learn more about skates as a research organism here: bit.ly/3Rmvq3F 📹 Bioquest

Happy #FluorescenceFriday! These are cultured fibroblasts imaged on a confocal microscope by postdoc Christina Daly. She is trying to understand how cells grow long signaling filopodia called cytonemes. Examples are visible extending from the orange cell in the image. 🤩 🧪 👩‍🔬

For #FluorescenceFriday I'm sharing the fantastic work of postdoc Sarah McLarnon! A follow up to our '23 Development paper where we asked: Does precise vascular patterning matter for function and what happens after ischemic injury? The results were surprising! journals.physiology.org/doi/full/10....

😍 I just love timelapse movies. It’s unbelievable that all of this happens in such a tiny fly! These cells don’t just move—they shape the unique spiral structure of the 🪰 testis. Amazing post by @maikbischoff.bsky.social — proof that science is art!!

For today's #FluorescenceFriday I'm thrilled to share that ScienceAdvances was so nice to pick my picture as this week's featured image! It's actually a still of a video😊 Check out the paper to learn more science.org/doi/10.1126/... #cellbio #devbio #cellmigration #science Thank you @aaas.org

It’s a quill? A sea pen? No—it’s a gill filament! 🪶🪸🐟 Under the microscope, this fish gill structure looks just like a sea pen. Fascinating how nature keeps circling back to the same shapes. Want to learn how gills develop? 👉 www.biorxiv.org/content/10.1... #FluorescenceFriday #Zebrafish

“The fish is a frog... is a chicken... is a mouse." In the 1980s, Kimmel defined a crucial stage at the onset of gastrulation when the prospective organization of the entire embryonic body plan emerged. It placed #zebrafish in the context of vertebrate developmental biology. #ZebrafishFunFacts 🧪

1) Branching morphogenesis is fundamental to animal development, shaping complex organs like lungs, kidneys, and vascular networks. Gills are another highly branched organ. Yet, the developmental processes behind gill formation in zebrafish remain poorly understood. #zebrafish #gills #microscopy
