--- _id: '6191' abstract: - lang: eng text: The formation of self-organized patterns is key to the morphogenesis of multicellular organisms, although a comprehensive theory of biological pattern formation is still lacking. Here, we propose a minimal model combining tissue mechanics with morphogen turnover and transport to explore routes to patterning. Our active description couples morphogen reaction and diffusion, which impact cell differentiation and tissue mechanics, to a two-phase poroelastic rheology, where one tissue phase consists of a poroelastic cell network and the other one of a permeating extracellular fluid, which provides a feedback by actively transporting morphogens. While this model encompasses previous theories approximating tissues to inert monophasic media, such as Turing’s reaction–diffusion model, it overcomes some of their key limitations permitting pattern formation via any two-species biochemical kinetics due to mechanically induced cross-diffusion flows. Moreover, we describe a qualitatively different advection-driven Keller–Segel instability which allows for the formation of patterns with a single morphogen and whose fundamental mode pattern robustly scales with tissue size. We discuss the potential relevance of these findings for tissue morphogenesis. article_processing_charge: No author: - first_name: Pierre full_name: Recho, Pierre last_name: Recho - first_name: Adrien full_name: Hallou, Adrien last_name: Hallou - first_name: Edouard B full_name: Hannezo, Edouard B id: 3A9DB764-F248-11E8-B48F-1D18A9856A87 last_name: Hannezo orcid: 0000-0001-6005-1561 citation: ama: Recho P, Hallou A, Hannezo EB.

Experimental evidence suggests that CCL2 correlates with inflammatory monocyte recruitment and induction of vascular activation, but the functionality remains open. Here, we show that endothelial Ccr2 facilitates pulmonary metastasis using an endothelial-specific Ccr2-deficient mouse model (Ccr2ecKO). Similar levels of circulating monocytes and equal leukocyte recruitment to metastatic lesions of Ccr2ecKO and Ccr2fl/fl littermates were observed. The absence of endothelial Ccr2 strongly reduced pulmonary metastasis, while the primary tumor growth was unaffected. Despite a comparable cytokine milieu in Ccr2ecKO and Ccr2fl/fl littermates the absence of vascular permeability induction was observed only in Ccr2ecKO mice. CCL2 stimulation of pulmonary endothelial cells resulted in increased phosphorylation of MLC2, endothelial cell retraction, and vascular leakiness that was blocked by an addition of a CCR2 inhibitor. These data demonstrate that endothelial CCR2 expression is required for tumor cell extravasation and pulmonary metastasis.\r\n\r\nImplications: The findings provide mechanistic insight into how CCL2–CCR2 signaling in endothelial cells promotes their activation through myosin light chain phosphorylation, resulting in endothelial retraction and enhanced tumor cell migration and metastasis." article_processing_charge: No article_type: original author: - first_name: Marko full_name: Roblek, Marko id: 3047D808-F248-11E8-B48F-1D18A9856A87 last_name: Roblek orcid: 0000-0001-9588-1389 - first_name: Darya full_name: Protsyuk, Darya last_name: Protsyuk - first_name: Paul F. full_name: Becker, Paul F. last_name: Becker - first_name: Cristina full_name: Stefanescu, Cristina last_name: Stefanescu - first_name: Christian full_name: Gorzelanny, Christian last_name: Gorzelanny - first_name: Jesus F. full_name: Glaus Garzon, Jesus F. last_name: Glaus Garzon - first_name: Lucia full_name: Knopfova, Lucia last_name: Knopfova - first_name: Mathias full_name: Heikenwalder, Mathias last_name: Heikenwalder - first_name: Bruno full_name: Luckow, Bruno last_name: Luckow - first_name: Stefan W. full_name: Schneider, Stefan W. last_name: Schneider - first_name: Lubor full_name: Borsig, Lubor last_name: Borsig citation: ama: Roblek M, Protsyuk D, Becker PF, et al.
