very nice interview Joaquín!

Thanks Luc! and yes it is! 😉

Here’s an embryonic axonal growth cone labeled with PK Mem dye (red) and tubulin (blue), imaged every 2 seconds. 🤩

cool!
here are chick commissural axons crossing the neural tube floor plate :): bsky.app/profile/axon...
May commissural axons find their way in here 🙏

Hi Erica,
thanks!
for 2D cultures: journals.biologists.com/jcs/article/...
for 3D cultures: www.frontiersin.org/journals/mol...
for live imaging I used 8-well IBIDI μ-slides with same PLL/Laminin coating and the same medium as in the JCS paper.
Cheers

The SynCAM synaptic cell adhesion molecules are involved in sensory axon pathfinding by regulating axon–axon contacts
ABSTRACT. Synaptic cell adhesion molecules (SynCAMs) are crucial for synapse formation and plasticity. However, we have previously demonstrated that SynCAMs are also required during earlier stages of ...

These ones are growing in a dish, but in a developing embryo or brain, each growth cone would be sniffing its way through a complex molecular terrain, often over long distances to find its correct synaptic partners.

Hi Luc, thanks!
it is indeed Spy555-FastAct.
Cheers

me too! They seem to be retraction fibers that are then fragmenting into these small vesicles. It has been described in some migrating cells/cancer cells before. We are now inestigating it in the context of axon growth and guidance!

Yes, it is, I wrote it in the ALT text but somehow it I can't see it. SPY555-FastAct

And sometimes accross the floor plate 🙂
