Brachiopod Wnt paper updated

I recently finished the revision of our paper about the Wnt signaling landscape in brachiopod development. This is work from my PhD time in the Hejnol Lab in Norway. We posted it on bioRxiv last September, and sent to a journal later that year. Following the reviewers’ feedback, we added new data, made significant improvements […]

Combinatorial Wnt landscape in Brachiopoda

Small note to say that our paper about the brachiopod Wnt landscape is now online on bioRxiv! Vellutini BC, Martín-Durán JM, Børve A, and Hejnol A (2023). Combinatorial Wnt signaling landscape during brachiopod anteroposterior patterning. https://doi.org/10.1101/2023.09.03.556047

The surface of a brachiopod embryo

This is a brachiopod embryo at the gastrula stage, showing its outer surface and the blastopore at the bottom. To visualize the cell membranes, I stained the sample for F-actin (filamentous protein fibers present in cells) and acquired a volumetric image stack in a confocal microscope. Then, I converted the original data to a 3D […]

Brachiopods and Japanese art

I visited Japan solely for the purpose of studying the Brachiopoda of the Japanese seas, and this step led to my accepting the chair of zoology in the Imperial University at Tokyo. Gradually I was drawn away from my zoological work, into archaeological investigations, by the alluring problem of the ethnic affinities of the Japanese […]
