Ivan Yow @mbisg.bsky.social @schmidtsciences.bsky.social investigated the mechanics of 3D spheroid formation. Fyn initiates spheroid formation via the RhoA-ROCK pathway, leading to increased tissue viscosity and tension - and may initiate cardiomyocyte transdifferentiation! #MBIMPG2025

Back to compressive stress with Frank van Drogen. Combining a phospho-proteomic approach with RNAi-based validation, he looked at the ERK5 pathway in mammary gland cells, showing how it reduces tension promoting the migratory response to compression. #MBIMPG2025

Great talk from Elizabeth Chen @echenlab.bsky.social on how cell-cell fusion is a conserved, asymmetric process - where one cell invades the other through invasive, mechanically stiff actin protrusions (bundled by dynamin & WIP!), to form a fusogenic synapse. #MBIMPG2025
