Very grateful to work w/ @yutian.bsky.social @hirokisayama.bsky.social Renaud Lambiotte for this foundational work! It made us rethink what constitutes a "unit" of interaction, leading to the idea that grouped coherent edges can form a single interaction (matrices). Hope this brings a new angle 🙂.

New interdisciplinary math+bio paper! Mouse liver assembloids model periportal architecture and biliary fibrosis. In vitro assembloids modelling the mouse liver periportal region were built to study processes causing scarring (cholestatic injury/biliary fibrosis) and the shape change this causes.

I posted about this paper this a while ago on another website, but figured I'd post it here now that I have a few followers. (Joint with @haharrington.bsky.social, Jacob Leygonie, @uzulim.bsky.social, and Louis Theran).
