The contributions of the cytoskeleton, specifically actomyosin tension, to these effects have been described, but the exact biophysical mechanisms that translate changes in cell geometry to changes in cell behaviour remain mostly unresolved. Using a variety of innovative materials techniques, we demonstrate that the nanostructure and lipid assembly within the cell plasma membrane are regulated by cell geometry in a ligand-independent manner. These biophysical changes trigger signalling events involving the serine/threonine kinase Akt/protein kinase B (PKB) that direct cell-geometry-dependent mesenchymal stem cell differentiation. Our study defines a central regulatory role by plasma membrane ordered lipid raft microdomains in modulating stem cell differentiation with potential translational applications. date: 2018-02-12 date_type: published publisher: NATURE PUBLISHING GROUP official_url: https://doi.org/10.1038/s41563-017-0014-0 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green article_type_text: Article verified: verified_manual elements_id: 1537883 doi: 10.1038/s41563-017-0014-0 lyricists_name: Bertazzo, Sergio lyricists_id: SBERT93 actors_name: Bertazzo, Sergio actors_id: SBERT93 actors_role: owner full_text_status: public publication: Nature Materials volume: 17 number: 3 pagerange: 237-242 pages: 8 issn: 1476-4660 citation: von Erlach, TC; Bertazzo, S; Wozniak, MA; Horejs, C-M; Maynard, SA; Attwood, S; Robinson, BK; ...
