Bionic Nanostructures Create Mechanical Signals to Mediate the Composite Structural Bone Regeneration Through Multi‐System Regulation

open access: yesAdvanced Science, EarlyView.
Inspired by the structural and functional characteristics of bone, bionic nanomaterials combined with nanotechnology can more accurately replicate stem cell niches, enabling the design of bone tissue engineering scaffolds with diverse nanoscale properties to promote stem cell migration, proliferation, and differentiation. This precise control over stem

Gut Microbiota Modulates Obesity‐Associated Skeletal Deterioration Through Macrophage Aging and Grancalcin Secretion

open access: yesAdvanced Science, EarlyView.
Obese gut‐microbiota derived lipopolysaccharides (LPS) induce bone marrow macrophage senescence and GCA secretion via activating TLR4/NF‐κB/MAPKs pathway. Clinically, obese patients are associated with higher serum GCA levels. Mice with depletion of GCA gene show resistance to skeletal deterioration caused by obesity and LPS‐induced chronic ...

Gas Bubbles from Biodegradable Magnesium Implants Convey Mechanical Cues and Promote Immune Cell Stimulation

open access: yesAdvanced Science, EarlyView.
Bubbles in soft tissue are the unavoidable consequence of magnesium implant degradation in patients, yet their biological significance remains unclear. Using advanced imaging and spatial transcriptomics, this study reveals a pronounced inflammatory and mechanical response near bubbles, contrasting with pro‐regenerative events closer to the implant ...

BEHAVIORAL MODEL OF A BASIC TRABECULAR-BONE MULTI-CELLULAR UNIT USING CELLULAR AUTOMATON

open access: yesVisión Electrónica, 2014
Bone remodeling is the biological process through which old bone tissue is transformed into new bone through the action of a basic unit of bone remodeling (BMU).

Bidirectional Interaction Between the Brain and Bone in Traumatic Brain Injury

open access: yesAdvanced Science, EarlyView.
Traumatic brain injury (TBI) disrupts the blood–brain barrier and activates neuroimmune responses, causing metabolic disturbances and long‐term bone mass loss. Concurrent fractures accelerate healing and enhance osteogenesis but disrupt regulatory mechanisms, leading to altered bone dynamics and exacerbating neuroinflammation, complicating recovery ...

Oscillating Magnetic Field Induced Bone Injury Repair by using Drug‐Free Micromotors

open access: yesAdvanced Science, EarlyView.
This work presents a payload‐free, minimally invasive approach for bone repair using magnetic hydrogel micromotors, which enhance bone regeneration via localized micromovement stimulation, achieving a twofold increase in new bone formation in vivo. Abstract Bone injury repair remains a significant clinical challenge due to the tissue's limited self ...
