Endothelial YAP Signaling Promotes Blood‐Spinal Cord Barrier Repair in Mice After Spinal Cord Injury

open access: yesAdvanced Science, EarlyView.
Endothelial YAP is required for blood‐spinal cord barrier repair after spinal cord injury. YAP‐dependent vascular repair is associated with ANGPT1/PI3K/AKT signaling in vivo and may involve endothelial‐pericyte paracrine interactions. By supporting vascular remodeling, tight junction restoration, restored pericyte coverage, and astrocyte‐vascular ...

Emerging mechanomedicines informed by mechanotransduction along the integrin–cytoskeleton–nucleus axis

open access: yesAPL Bioengineering
Mechanical forces are fundamental to the formation of normal biological tissues and the maintenance of physiological health. These forces are transmitted from the extracellular environment to the cell interior through cell–cell and cell–ECM interactions,

Matrix Stiffness Enhances Odontogenic Differentiation of DPSCs through Membrane Curvature Protein Baiap2‐Modulated Exosome Release

open access: yesAdvanced Science, EarlyView.
Matrix stiffness softening is identified as a previously underappreciated feature in deep caries. Higher stiffness drives exosome release in dental pulp stem cells through a coordinated mechanism involving PI3K–AKT‐regulated Baiap2 and kinesin‐1, thereby promoting odontogenic differentiation.

Deciphering Nuclear Mechanobiology in Laminopathy

open access: yesCells, 2019
Extracellular mechanical stimuli are translated into biochemical signals inside the cell via mechanotransduction. The nucleus plays a critical role in mechanoregulation, which encompasses mechanosensing and mechanotransduction.

In Situ Programmable Modulation of Hydrogel Stiffness for Stage‐Adaptive Bone Regeneration

open access: yesAdvanced Science, EarlyView.
Near‐infrared (NIR) irradiation triggers Ca2+ release from thermoresponsive nanocarriers, enabling in situ stiffening of an adaptive hydrogel from a soft to a stiff state, thereby sequentially supporting mesenchymal stromal cell stemness and osteogenic differentiation for stage‐adaptive bone regeneration.

High-Force Magnetic Pulling Cytometer for Probing Cellular Mechanotransduction Pathways

open access: yes, 2019
Cellular domains accrue mechanical fluctuations as a means of communication. The process by which these mechanical forces are transmitted into cellular signals is termed, mechanotransduction.

Bioadhesive‐Integrated 3D‐Printed Multilayer Scaffolds Secure a Mechanically‐Stable Osteoimmune Niche for Enhanced Bone Augmentation

open access: yesAdvanced Science, EarlyView.
A 3D‑printed multilayer adhesive scaffold, firmly anchored to bone defects by simple finger pressing, suppresses micromotion and secures mechanical stability of the osteogenic niche. This stabilization likely contributes to the enhanced bone augmentation by fostering a pro‑regenerative mechano‐immune profile—characterized by M2‑like macrophage ...

The Energetics of Rapid Cellular Mechanotransduction

open access: yes, 2022
Cells throughout the human body detect mechanical forces. While it is known that the rapid (millisecond) detection of mechanical forces is mediated by force-gated ion channels, technological limitations have precluded a detailed quantitative ...

An Innervated Human Skin Equivalent that Electrically Encodes Mechanical and Thermal Stimuli

open access: yesAdvanced Science, EarlyView.
An innervated human skin equivalent is integrated with high‐density microelectrode arrays to reveal how engineered free nerve ending–like structures translate touch and temperature into electrical codes. Mechanical indentation and thermal stimulation engage the engineered somatosensory circuitry and evoke distinct firing and waveform signatures ...

Endothelial miR‐15a/16‐1 Regulation of SYNE1 Mediates Structural and Functional Recovery after Traumatic Brain Injury

open access: yesAdvanced Science, EarlyView.
Endothelial miR‐15a/16‐1 deletion promotes long‐term recovery after traumatic brain injury by restoring SYNE1 expression. Enhanced endothelial SYNE1 preserves vascular integrity, protects white and gray matter, and improves neurological function. The endothelial miR‐15a/16‐1–SYNE1 axis emerges as a key regulator of neurovascular repair and a potential ...
