Cells sense and migrate across mechanically dissimilar environments throughout development disease progression. However, it remains unclear whether mechanical memory of past empowers cells to navigate new, three-dimensional extracellular matrices. Here, we show that previously primed on stiff, compared with soft, matrices generate a higher level forces remodel collagen fibers promote invasion. This priming advantage persists in dense or stiffened collagen. We explain this memory-dependent, cross-environment cell invasion through lattice-based model wherein stiff-primed cellular minimize energy required for future According our model, transfer their the matrix via alignment tension, remodeled informs Thus, memory-laden overcome mechanosensing softer challenging cell-matrix memory. Consistent predictions, depletion yes-associated protein destabilizes remodeling before release tension laser ablation disable fiber by lysyl-oxidase inhibition, both which disrupt cell-to-matrix hamper These results have implications cancer, fibrosis, aging, where potential may prolonged response.

Increased mechanical loading imposed induces an actin-related protein 2/3 (ARP2/3)-complex-dependent dense actin network, enhances Na + /H exchanger (NHE1) polarization through actin-binding partner ezrin. NHE1 promotes swelling increased membrane tension, which, turn, activates transient receptor potential cation vanilloid 4 (TRPV4) mediates calcium influx, leading RHOA-dependent contractility.

Abstract Across complex, multi-time and -length scale biological systems, redundancy confers robustness resilience, enabling adaptation increasing survival under dynamic environmental conditions; this review addresses ubiquitous effects of cytoskeletal remodelling, triggered by biomechanical, biophysical biochemical cues, on stem cell mechanoadaptation emergent lineage commitment. The cytoskeleton provides an adaptive structural scaffold to the cell, regulating emergence structure-function relationships during tissue neogenesis, both in prenatal development as well postnatal healing. Identification mapping mechanical cues conducive remodelling may help establish contexts that can be used prospectively translational design specifications target neogenesis for regenerative medicine. In review, we summarize findings context early healing, its relevance guiding commitment targeted regeneration. We highlight how cytoskeleton-targeting chemical agents modulate differentiation govern responses cells’ emerging form function. further methods spatiotemporal visualization measurement properties cells, a function adaptation. Research these areas facilitate translation own healing potential improve materials, therapies, devices

Advances in bioprinting have enabled the fabrication of complex tissue constructs with high speed and resolution. However, there remains significant structural biological complexity within tissues that is unable to recapitulate. Bone, for example, has a hierarchical organization ranging from molecular whole organ level. Current techniques materials employed imposed limits on scale, speed, resolution can be achieved, rendering technique reproduce hierarchies cell-matrix interactions are observed bone. The shift toward biomimetic approaches bone engineering, where hydrogels provide biophysical biochemical cues encapsulated cells, promising approach enhancing function development vitro modeling. A major focus modeling creating dynamic microenvironmental niches support, stimulate, direct cellular processes formation remodeling. Hydrogels ideal imitating extracellular matrix since they engineered present various whilst allowing bioprinting. Here, recent advances 3D niche conducive engineering models reviewed.

Tissue morphogenesis, homoeostasis and repair require cells to constantly monitor their three-dimensional microenvironment adapt behaviours in response local biochemical mechanical cues. Yet the parameters of cellular probed by vivo remain unclear. Here, we report mechanics that probe situ during zebrafish presomitic mesoderm differentiation. By quantifying both endogenous cell-generated strains tissue mechanics, show individual stiffness associated with deformations supracellular, foam-like architecture. Stress relaxation leads a perceived decreases over time, probing softest regime. We find most parameters, including those cells, vary along anteroposterior axis as mesodermal progenitors differentiate. These findings expand our understanding mechanosensation might aid design advanced scaffolds for engineering applications.

Pulmonary hypertension (PH) is associated with increased expression of VEGF-A (vascular endothelial growth factor A) and its receptor, VEGFR2 2), but whether how activation signal participates in the pathogenesis PH unclear.VEGF-A/VEGFR2 Y949-dependent vascular leak were investigated lung samples from patients mice exposed to hypoxia. To study their mechanistic roles hypoxic PH, we examined right ventricle systolic pressure, ventricular hypertrophy, pulmonary vasculopathy mutant carrying knock-in phenylalanine that replaced tyrosine at residual 949 (Vefgr2Y949F) conditional deletion Vegfr2 after chronic hypoxia exposure.We show leads excessive both mice, this because an overactivated VEGF-A/VEGFR2 Y949 signaling axis. In context Yes1 c-Src subsequent VE-cadherin phosphorylation cells are involved Y949-induced permeability. Abolishing by Vefgr2Y949F point mutation was sufficient prevent permeability inhibit macrophage infiltration Rac1 smooth muscle under exposure, thereby leading alleviated manifestations, including muscularization distal arterioles, elevated hypertrophy. It important found myeloid macrophages trivial dispensable for hypoxia-induced abnormalities PH. contrast selective blockage signaling, disruption entire promotes development PH.Our results support notion determinant might serve as attractive therapeutic target pathway disease.
