A Cyerce kikutarobabai nudibranch from Okinawa. This one is very tiny - 3 mm long. I found it bouncing in the waves being torn from the reef by the water power. It was flying like a pink dot among the muddy water with debris. I did not expect much before I brought it under the microscope.

Another try to post a video: starfish larva, 1 mm long. This is a brachiolaria stage.

What is new in the neural crest domain? Which neural crest-related studies do you find fun and exciting? Let’s have an interesting discussion. I feel like I want to go back to look into the pigmentation patterns and evolution of multipotency.

Our sweet cubozoan Tripedalia. Their rhopalia contain image-forming eyes and are bilaterally-symmetrical.

We have different hobby projects in the lab, and some of them focus on cnidarians. Here i filmed Cotylorhiza tuberculata jellyfish 🤩

(16) Some perturbed clones showed completely novel behavior (in the case of Ptch1 knock-out) or distortion of already existing clonal programs (Fgfr1, Fzd2, and other knock-outs) — it wasn't possible to distinguish these cases without clonal information.

(15) Correlation doesn't imply causation, and to study the latter, we added to the plasmid with barcode also different gRNAs and injected viruses with these plasmids into Cas9 mice to perform perturbation screening together with lineage tracing.

(14) In application to the mesenchyme from the head, we used our approach to identify spatial gene expression signatures (similar to the Hox-code in the trunk) that were later validated on publicly available high-resolution spatial transcriptomics datasets.

(12) We compared chondrogenic trajectories among "clone types" and discovered molecular correlates of differences in clonal potency. This also allowed us to distill a "core" common pathway of a chondrocyte generation scrubbed of any kind of spatial signature.

(11) We then focused on mesenchyme and observed that different clonal clusters create "stripes" on gene expression embedding. Many of them contained cartilage — and the next reasonable question was what was common and different between these cells?

(10) We show that these clusters correspond to clones from different domains (e.g. neuronal/mesenchymal) as well as different body parts (based on Hox expression) — showing how well-regulated cell proportions are at the clonal level by spatial patterning.
