Can small extracellular vesicles guide growing axons? Our new preprint provides evidence that small extracellular vesicle (sEV) secretion regulates axon guidance at a key ventral midline choice point during spinal cord development. biorxiv.org/content/10.64898… #neuroscience #EV

This is how actin shapes the neuronal growth cone 🔬 When a neuron grows, it doesn’t just extend blindly. It actively moves, explores its surroundings, and makes decisions along the way. #Neuroscience #ScienceCommunication #Microscopy #brain #Science #LifeSciences #neuron

This Is What Drives Axon Growth. Axon growth is powered by the actin cytoskeleton at the growth cone. Here, filamentous actin dynamics drive fast, directed axon extension in real time. #Fluorescencefriday #science #neuroscience

Thrilled to collaborate with @ZhixingChen2 Lab @PKU1898! We tested new PK Mem dyes—gentle, photostable tools to label the plasma membrane in live neurons, making it easier to track growth cone motility & axonal transport. #liveimaging #neuroscience tiny.cc/3qhp001

This time-lapse captures 17h of axonal growth from a chick dorsal root ganglion explant, seen through the actin cytoskeleton using live imaging. I just submitted this video to the Nikon Small World in Motion competition. Today is the last day to upload yours!😉 #neuroscience

Time-lapse recording of floorplate cytonemes (green) interacting with axons (magenta). 1 image taken every second for 10 min (played at 30 fps). Cytonemes love interacting with axons! 💚#FluorescenceFriday

Most definitely! 😁

It even looks like the growth cone on the left is doing a breakdance 🌊 to propel the particle to the other side! #FluorescenceFriday
