It is increasingly clear that mechanotransduction pathways play important roles in regulating fundamental cellular functions. Of the basic mechanical functions, determination of morphology critical. Cells typically use many mechanosensitive steps and different cell states to achieve a polarized shape through repeated testing microenvironment. Indeed, determined by microenvironment periodic activation motility, mechanotesting, mechanoresponse functions hormones, internal clocks, receptor tyrosine kinases. Patterned substrates controlled environments with defined rigidities limit range behavior influence state decisions are thus very useful for studying these steps. The recently rigidity sensing process provides good example how cells repeatedly test their also linked cancer. In general, aberrant extracellular matrix mechanosensing associated numerous conditions, including cardiovascular disease, aging, fibrosis, correlate changes tissue composition. Hence, detailed descriptions involved responding needed better understand both mechanisms homeostasis pathomechanisms human disease.

Abstract During natural tissue regeneration, microenvironment and stem cell niche including cell–cell interaction, soluble factors, extracellular matrix (ECM) provide a train of biochemical biophysical cues for modulation behaviors functions. Design functional biomaterials to mimic the tissue/cell have great potentials regeneration applications. Recently, electroactive drawn increasing attentions not only as scaffolds adhesion structural support, but also modulators regulate cell/tissue function, especially electrically excitable cells tissues. More importantly, electrostimulation can further modulate myriad biological processes, from cycle, migration, proliferation differentiation neural conduction, muscle contraction, embryogenesis, regeneration. In this review, endogenous bioelectricity piezoelectricity are introduced. Then, design rationale is discussed imitating dynamic microenvironment, well their mediated applying pathways. Recent advances in systematically overviewed fate mainly nerve bone engineering, cardiac engineering. Finally, significance simulating native emphasized open challenges future perspectives concluded.

The implantation of any foreign material into the body leads to development an inflammatory and fibrotic process-the reaction (FBR). Upon a tissue, cells immune system become attracted attempt degrade it. If this degradation fails, fibroblasts envelop form physical barrier isolate it from rest body. Long-term medical devices faces great challenge presented by FBR, as cellular response disrupts interface between implant its target tissue. This is particularly true for nerve neuroprosthetic implants-devices implanted nerves address conditions such sensory loss, muscle paralysis, chronic pain, epilepsy. Nerve neuroprosthetics rely on tight interfacing tissue electrodes detect tiny electrical signals carried axons, and/or electrically stimulate small subsets axons within nerve. Moreover, advances in microfabrication drive field increasingly miniaturized implants, need stable, intimate implant-tissue likely quickly limiting factor new technologies. Here, we provide overview material-cell interactions leading FBR. We review current technologies (cuff, penetrating, regenerative interfaces) how long-term function these limited Finally, discuss properties (such stiffness size), pharmacological therapies, or use biodegradable materials may be exploited minimize FBR implants improve their stability.

ABSTRACT YAP and TAZ proteins are transcriptional coactivators encoded by paralogous genes, which shuttle between the cytoplasm nucleus in response to multiple inputs, including Hippo pathway. In nucleus, they pair with DNA-binding factors of TEAD family regulate gene expression.

One of the most striking adaptations to exercise is skeletal muscle hypertrophy that occurs in response resistance exercise. A large body work shows a mammalian target rapamycin complex 1 (mTORC1)-mediated increase protein synthesis key, but not sole, mechanism by which causes hypertrophy. While much signaling cascade has been identified, initiating, exercise-induced and hypertrophy-stimulating stimuli have remained elusive. For purpose this review, we define an signal as "hypertrophy stimulus," sensor such sensor." In review discuss our current knowledge specific mechanical stimuli, damage/injury-associated metabolic stress-associated triggers, potential stimuli. Mechanical signals are prime candidates, filamin-C-BAG3-dependent regulation mTORC1, Hippo, autophagy plausible albeit still incompletely characterized sensor.

Recent evidence clearly shows that cells respond to various physical cues in their environments, guiding many cellular processes and tissue morphogenesis, pathology, repair. One aspect is gaining significant traction the role of local geometry as an extracellular cue. Elucidating how affects cell behavior is, indeed, crucial design artificial scaffolds understand growth remodeling. Perhaps most fundamental descriptor surface curvature, a growing body confirms curvature spatiotemporal organization tissues. While well-defined differential geometry, remains somewhat ambiguously treated biological studies. Here, we provide more formal framework, based on notions mean Gaussian summarize available guidance at levels. We discuss involved mechanisms, highlighting interplay between tensile forces substrate forms foundation guidance. Moreover, show relatively simple computational models, some application flow, are able capture experimental remarkably well. Since principles could be leveraged for regeneration, implications geometrical scaffold also discussed. Finally, perspectives future research opportunities provided.
