Cell migration in dense microenvironments

چکیده
The nucleus has been viewed as a passenger during cell migration that functions merely to protect the genome. However, increasing evidence shows is an active organelle, constantly sensing surrounding environment and translating extracellular mechanical inputs into intracellular signaling. nuclear envelope large membrane reservoir which serves buffer for it unfolds without its tension. In contrast, when cells cope with strain, such through solid tumors or dense interstitial spaces, folds stretch, tension sometimes causing rupture. Different degrees of regulate cellular behaviors functions, especially in move grow within matrices. crosstalk between critical component modulation function navigate packed microenvironments. Moreover, there link regimes unfolding different behaviors, from orchestrated signaling cascades perturbations damage.

Cell migration on material-driven fibronectin microenvironments†
Cell migration is a fundamental process involved in a wide range of biological phenomena. However, how the underlying mechanisms that control migration are orchestrated is not fully understood. In this work, we explore the migratory characteristics of human fibroblasts using different organisations of fibronectin (FN) triggered by two chemically similar surfaces, poly(ethyl acrylate) (PEA) and ...
متن کاملTumor Cell Migration Through Tissue Microenvironments
Three-dimensional (3-D) molecular contacts, contributed by the basement membrane, ECM, and adjacent cells, provide an architectural context within which a normal cell functions. Adhesive structures are physical connections between the cytoskeleton (CSK) and the ECM (an extracellularmatrix connection) or between the CSK and the CSK of other cells (a cell-cell connection). There are several adhes...
متن کاملDendritic Cell Migration and Traction Force Generation in Engineered Microenvironments
Dendritic cells (DCs) are potent initiators of the adaptive immune response. Their trafficking from sites of inflammation to lymphoid tissue is essential to their function. Exactly how dendritic cells integrate multiple chemotactic cues to organize an accurate migratory path is not fully understood. We first characterize DC random motility (chemokinesis) on extracellular matrix proteins in the ...
متن کاملWater Permeation Drives Tumor Cell Migration in Confined Microenvironments
Cell migration is a critical process for diverse (patho)physiological phenomena. Intriguingly, cell migration through physically confined spaces can persist even when typical hallmarks of 2D planar migration, such as actin polymerization and myosin II-mediated contractility, are inhibited. Here, we present an integrated experimental and theoretical approach ("Osmotic Engine Model") and demonstr...
متن کاملDiffusion dependent cell behavior in microenvironments.
Understanding the interaction between soluble factors and cells in the cellular microenvironment is critical to understanding a wide range of diseases. Microchannel culture systems provide a tool for separating diffusion and convection based transport making possible controlled studies of the effects of soluble factors in the cellular microenvironment. In this paper we compare the proliferation...
