The regulation of stem cell fate and its application in neural regeneration
Regulating stem cell fate is crucial for neural regeneration. This review summarizes key physical, biological, and chemical strategies and their applications in repairing nerve injuries, providing new insights for regenerative medicine. Abstract Regulating the fate of stem cells (SCs) is a key technical problem in the field of regenerative medicine and

Nuclear deformation mediates liver cell mechanosensing in cirrhosis
Background & Aims: Liver stiffness is increased in advanced chronic liver disease (ACLD) and accurately predicts prognosis in this population. Recent data suggest that extracellular matrix stiffness per se may modulate the phenotype of liver cells ...

Heat Stress Triggers Nuclear Invagination and Spatial Compartmentalization of Protein Metabolism
Cells adapt heat stress to shape a nuclear invagination region function as “protein metabolism hotspots”, where both protein production and degradation are enhanced. ABSTRACT Heat stress is a common challenge for cells, causing multiple types of cellular damage while triggering complex stress responses, including the highly conserved mechanism known as

Nuclear dysfunction in aging and neurodegeneration
Abstract Neurodegenerative diseases are characterized by a loss of neuronal function and structure, often in a region‐specific manner. Multiple factors contribute to neuronal dysfunction and death, including pathogenic protein buildup, protein mislocalization, and inflammation. Despite extensive research, the common mechanisms driving neurodegeneration

Astrocytes are key sensors and transducers of biomechanical stimuli within the central nervous system. Astrocyte development is highly dependent on mechanical stimuli such as surrounding tissue stiffness and biomechanical strain. Mechanosensory pathways including integrins, connexins and pannexins, and mechanosensitive channels regulate astrocyte ...

Single Cell Mechanics in Disease Progression
Cells transmit distinct mechanical forces through ECM adhesion and cell–cell junctions and actomyosin‐generated traction forces are transmitted to the substrate through integrin‐based focal adhesions. Mechanical signals are further transmitted to the nucleus via the LINC complex, connecting the cytoskeleton to the nuclear lamina. These forces integrate

This study investigates how CTCs survive varying shear stress during hematogenous metastasis. We uncover a self‐protection mechanism, by which non‐adherent CTCs adapt to high shearing milieu through accumulated cytoplasmic myosin‐mediated disruption of myosin‐actin binding, attenuating force transmission into chromatin to protect CTCs from shear ...

Sono‐Mechanogenetics: Linking Ultrasound Physics With Cellular Mechanobiology
Sono‐mechanogenetics links ultrasound physics with cellular mechanotransduction to enable noninvasive control of engineered biological systems. Acoustic forces generate distinct deformation modes that activate intracellular signaling pathways, which can be coupled to synthetic gene circuits to regulate diverse cellular functions, including gene ...

This work develops dynamically softening polyacrylamide hydrogels for time‐resolved imaging during continuous mechanical transitions. The study revealed that mechanotransduction is biphasic; YAP/TAZ inactivation is driven by early loss of the nucleocytoskeletal continuum connecting subnuclear adhesions, F‐actin, and the nuclear envelope, coupled with ...
