Beautiful story from the Krndija lab, tackling the unexpected challenges of complex epithelia. They show side-effects (or are they?) of building an epithelium out of distinct cell types, with junctional fractures at the heterotypic interface. Is there any reinforcement of 3CJunctions?

🥳 Thrilled to share our lab's first preprint, led by our talented postdoc Justine Creff! 👩🏻‍🔬 We tackled a fundamental question: how the epithelium withstands mechanical stress at the interface of cells with distinct geometries and mechanics, such as enterocytes (E) and goblet cells (G) (1/9)
