Active epithelial tissues can still behave like glass, with slow, trapped cell regions beside faster ones. Simulations matched the pattern only when mechanochemical feedback and crowding were included. doi.org/hb9x7v

Unraveling the glass-like nature of epithelial tissues
In a new study, researchers at the Indian Institute of Science (IISc) have resolved a longstanding mystery by showing how epithelial tissues exhibit slow-moving, glass-like behavior despite their fast-paced biological activity.

I recently gave a talk on Glass Transition in Epithelial Tissues, a collaboration b/w my group and Medhavi Vishwakarma's group at IISc. Many thanks to @bppbseminar.bsky.social for hosting me. Here is the link: www.youtube.com/watch?v=E3ov.... Papers in the comment below. 👇 @epimechfc.bsky.social

Please join BPPB on Fri Aug 14 @ 11 ET for talks by Max Brambach (How self-tolerance can be faster than immunity and what that could mean for cancer therapy) & Sumantra Sarkar @sumantrasarkar.bsky.social (Glass transition in epithelial tissues). For more info, see sites.google.com/view/bppb-se....

From single-celled organisms to ciliated epithelia in metazoans, precise positioning of basal bodies (BBs), which anchor motile cilia, is essential for generating fluid flows. Here, I, @raghavan-thiaga.bsky.social, will take you on a brief tour of how cells build this spatial organization.

Hundreds of organelles. Disorder → order. No blueprint. The switch? Actin crosslinking. The moment the meshwork forms, Basal Body dynamics shift from diffusive to subdiffusive. Same transition. Same developmental window - Every time. New preprint from my postdoc. Full thread👇

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.

Mechanosensitive feedback organizes cell shape and motion during hindbrain neuropore morphogenesis
Pérez-Verdugo et al. show that hindbrain neuropore closure is driven by surface ectoderm actomyosin purse-string tension and active migration. These forces create reproducible patterns of cell elongat...
