Abstract:
Directed cell migration towards a softer environment is called negative durotaxis. The mechanism and pathological relevance of negative durotaxis in tumor progression still requires in-depth investigation. Here, we report that YAP promotes the negative durotaxis of melanoma. We uncovered that the RhoA-myosin II pathway may underlie the YAP enhanced negative durotaxis of melanoma cells. Acral melanoma is the most common subtype of melanoma in non-Caucasians and tends to develop in a stress-bearing area. We report that acral melanoma patients exhibit YAP amplification and increased YAP activity.

Abstract:
The mechanical properties of a cell’s microenvironment influence many aspects of cellular behavior, including cell migration. Durotaxis, the migration toward increasing matrix stiffness, has been implicated in processes ranging from development to cancer. During durotaxis, mechanical stimulation by matrix rigidity leads to directed migration. Studies suggest that cells sense mechanical stimuli, or mechanosense, through the acto-myosin cytoskeleton at focal adhesions (FAs); however, FA actin cytoskeletal remodeling and its role in mechanosensing are not fully understood. Here, we show that the

Abstract:
Mechanical compliance has been demonstrated to be a key determinant of cell behavior, directing processes such as spreading, migration, and differentiation. Durotaxis, directional migration from softer to more stiff regions of a substrate, has been observed for a variety of cell types. Recent stiffness mapping experiments have shown that local changes in tissue stiffness in disease are often accompanied by an altered ECM composition in vivo. However, the importance of ECM composition in durotaxis has not yet been explored. To address this question, we have developed and characterized a polyacr

Abstract:
Les cellules peuvent migrer de façon aléatoire ou dirigée. La durotaxie est un phénomène de migration dirigée, si les cellules ont le choix, elles vont préférentiellement migrer vers des environnements durs, plutôt que mous. Il a été montré que les cellules pouvaient retenir des informations de leurs environnements passés, ce qui modifie leurs migrations. Ceci est appelé « mémoire mécanique ». Nous avons montré que la mémoire mécanique avait un impact sur la durotaxie des cellules. De plus, nos résultats suggèrent que les cellules sont capables d’associer des stimuli rencontrés dans leur passé

Abstract:
Tissue Engineering is a very promising research field for the development of natural biological substitutes that restore damaged tissue functions. Cells play a crucial role in tissue regeneration and repair due to their characteristics of proliferation and differentiation, cell-to-cell interaction, biomolecular production and extracellular matrix formation. In particular cell migration is a phenomenon that is involved in different physiological processes such as morphogenesis, wound healing and new tissue deposition. In the absence of external guiding factors it is essentially a phenomen

Abstract:
Cell migration is a fundamental element in a variety of physiological and pathological processes. Alteration of its regulatory mechanisms leads to loss of adhesion and increased motility, critical steps in the initial stages of metastasis. Consequently, cell migration has become the focus of intensive experimental and theoretical studies; however the understanding many of its mechanisms remains elusive. Cell migration is the result of a periodic sequence of protrusion, adhesion remodeling and contraction stages that leads to directed movement towards external stimuli. The spatio-temporal coord

Abstract:
Cell migration is a complex physiological process that is important from embryogenesis to senescence. In vivo, the migration of cells is guided by a complex combination of signals and cues. Directed migration is typically observed when one of these cues is presented to cells as a gradient. Several studies have been conducted into directed migration on gradients that are purely mechanical or chemical. Our goal was to investigate cellular migratory behavior when cells are presented with a choice and have to choose between increasing substrate rigidity or higher protein concentration. We chose

Abstract:
Many studies have focused on the effects of substrate rigidity on cell traction, migration, and differentiation [1–3]. Most cells are known to migrate toward the stiffer substrate, a phenomenon known as durotaxis. Recent reports have also demonstrated the ‘depth-sensing’ ability of cells on soft hydrogels where cell behaviors on thin gels are more similar to those on stiffer substrates [4–5]. Taking advantage of the high fidelity of microfabrication and soft lithography products, we created novel composite substrates composed of a top layer of collagen hydrogel and an underlying microstructure

Abstract:
Adult mesenchymal stem cells (MSCs) have recently been shown to be responsive to the properties of their adjacent extracellular niche, most notably physical parameters such as topography and elasticity. Elasticity varies dramatically between tissues that MSCs inhibit, which drives elasticity-based differentiation into neurons, muscle, bone, etc. However within tissues, distinct elasticity gradients, brought on by pathological conditions, e.g. myocardial infarction ∼ 8.67 ± 1.50 kPa/mm, or through normal tissue variation, e.g. 0.58 ± 0.88 kPa/mm, could drive MSC migration. In fact, MSCs appear
