A new strain of transgenic Platynereis. At this stage, this is still a great joy. Hopefully, several more will follow soon ...
I hope other teams are making progress with this notoriously resistant species. Let's make Platy the marine D melanogaster ! #platynereis #wormwednesday #evodevo
I am thrilled to share with you our new paper published in @emboreports.org - Led by our fantastic PhD student Loïc Bideau with the help of many lab members.

Happy to be involved in UNICIL, our new Wellcome Trust Discovery project coordinated by @micromotility.bsky.social
We will study ciliary dynamics across scales and organisms. A long-term #postdoc position will be available at Heidelberg University […]

I’m thrilled to join @tessmarraiblelabs.bsky.social at the University of Vienna as an #MSCA Postdoctoral Fellow. I'm looking forward to learning from such an inspiring team and to embarking on this new research chapter. 🌊🐛 🌕

Excited to welcome @mariacocurullo.bsky.social to the Tessmar-Raible lab, who secured a prestigious #MSCA Postdoctoral fellowship to explore how monthly timing shapes brain #plasticity in Platynereis dumerilii — and how light pollution at night may disrupt it.

Kyojiro Ikeda @beingkyo.bsky.social @univie.ac.at presenting now at #DevStem2025 @viennabiocenter.bsky.social on first mechanistic & molecular regulators of #bristle biogenesis in the #Platynereis model. Also check Kyojiro's recent @naturecomms.bsky.social publication www.nature.com/articles/s41...
Paper alert! We are a little late but very proud of the team's latest study on the neurogenic functions of the Notch signalling pathway during #regeneration and posterior elongation in #platynereis. @ijmonod.bsky.social @cnrsbiologie.bsky.social @upcite.bsky.social

The revised version of our #Platynereis #connectome paper is now out:

Cell-type-level annotation of the whole organisms, including synaptic and desmosomal connectomes. Can be explored with CATMAID here […]

Lunar lessons from #Platynereis: what can marine #worms teach us about our relationship with the moon?

The origin of diaplectic waves (perpendicular direction) is most mysterious. To study this, we turned to the 1-2 day #Platynereis larva -> @jekely.biologists.social.ap.brid.gy 's favourite organism!
The larva exhibits a robust metachronal wave around its equator (cilia beat in/out of the page)

Image of an adult Platynereis worm. The 24-hpf trochophore larva swims in a left handed helical path using cilia, which beat with a characteristic pattern. Scanning electron microscopy (SEM) image of a 24hpf larva spliced with a schematic showing axis orientation and swimming direction. A single larva held by a micropipette. The ciliary band comprises large, distinct multiciliated cells distributed regularly around the prototroch band.
We published a new preprint on the biophysics of ciliary metachronal waves in the Platynereis larva. www.biorxiv.org/content/10.1101/2025.02.... In collaboration with @micromotility.bsky.social and Rebecca Poon #cilia #biology #biophysics #platynereis 1/6
New preprint from Rebecca's PhD! did you know that the ciliary band metachronal wave in #Platynereis is a series of tiny waves within each multiciliated cell! What happens if you ablate some cilia?? 🌊😱
Cool #cilia collab w/ @jekely.biologists.social.ap.brid.gy!

This one is really for the #Platynereis aficionados. #WormWednesday
Four boxes of worms. Same age (2 months). Same conditions/incubator.
And four different algal/microbial mats growing in them.
Great to ses that study out in MBE. This is the result of an effective collaboration with @stemdevevo.bsky.social. Aurore Vullien (joint PhD student) et al has studied the evolution and role of ROS in metazoan regeneration using #nematostella and #platynereis. Congrats to all. Highlights below.
#Platynereis bristleworms grow by adding new segments at their posterior ends using a #StemCell zone. But what happens if the zone is cut off? First authors Alexander Stockinger and Leonie Adelmann @univie.ac.at used a time-resolved #SingleCell #scRNAseq approach to tackle this question... (2/7)
It was a great pleasure to participate to this course and present #platynereis #regeneration to very motivated students! Also the opportunity to catch up with @MaxYunLab ! https://x.com/institut_curie/status/1826182466010484912
Zoé is on stage for a flash talk presenting her poster on #platynereis regeneration at the @IJMonod YSC scientific day !
Happy to see our last paper on #platynereis regeneration on this subject collection https://x.com/amjeve/status/1843937750971809900
Beautiful weather at last for the 3rd day of the #EMBO regeneration meeting in the south of France. The right day to present our #platynereis work
On my way to the #EMBO regeneration meeting! Looking forward to see great science, friends and to present our work on #platynereis ! So far the weather for the south of France is a bit disappointing …
The final version of our paper on how #Platynereis larvae respond to pressure has now been published
