Our latest work on shape-programmable tissues is out in @science.org. By positioning topological defects in cellular nematics, we encode frustrated 2D force fields that relax into predictable 3D shapes. Collaboration with Marino Arroyo’s lab, led by @pauguillamat.bsky.social at @ibecbarcelona.eu.

We had covered the history of traction force microscopy (TFM) earlier:
bsky.app/profile/epim...

But what about applying TFM into more physiologically relevant systems, such as those in 3D?

I am @barrasa-fano.bsky.social and I'll be your guide through this thread on #3DTractionForceMicroscopy.

I'm happy to present our new tool, EpiCure, a napari plugin to ease correction of segmentation and tracking of epithelia movies, developed in @devstempasteur.bsky.social

We developed image analysis tools to capture the nematic orientation field of 3D tissue surfaces. Tested on epithelial aggregates, zebrafish hearts, myoblasts on spheres & micro-vessels, we combined soft matter physics with exp. biology.
