An Organ‐on‐Chip Platform for Strain‐Controlled, Tissue‐Specific Compression of Cartilage and Mineralized Osteochondral Interface to Study Mechanical Overloading in Osteoarthritis

open access: yesAdvanced Healthcare Materials, EarlyView.
A mechanically active OsteoChondral Unit (OCU)‐on‐Chip platform mimicking the OCU's functional anatomy and the strain gradient across the osteochondral interface is presented. Upon compartment‐specific hyperphysiological compression, the model replicates mechanisms observed in osteoarthritis (OA) progression, such as calcium crystal accumulation ...

Impact of Nanoparticle Stiffness on Endosomal Escape and Signaling Pathways in Cytosolic Delivery

open access: yesAdvanced Healthcare Materials, EarlyView.
Nanoparticle (NP) stiffness affects cellular uptake, but its impact on intracellular distribution remains unclear. This study synthesizes silica nanocapsules with varying stiffness, inspired by viral mechanisms, and applies assays to measure cellular uptake and escape efficiency.

Multiscale Profiling of Nanoscale Metal‐Organic Framework Biocompatibility and Immune Interactions

open access: yesAdvanced Healthcare Materials, EarlyView.
A multi‐scale, hierarchical ‘Safety‐by‐Design’ pipeline combining machine learning, ex vivo human blood assays, and in vivo models enables the systematic immunotoxicity and biocompatibility profiling of nanoscale metal‐organic frameworks, accelerating their safe clinical translation. Abstract The clinical translation of metal‐organic frameworks (MOFs) –

Therapeutic Implants: Mechanobiologic Enhancement of Osteogenic, Angiogenic, and Myogenic Responses in Human Mesenchymal Stem Cells on 3D‐Printed Titanium Truss

open access: yesAdvanced Healthcare Materials, EarlyView.
This study investigates a synergistic effect between 3D‐printed surface features and mechanical micro‐strain in enhancing the osteogenic, angiogenic, and myogenic responses of human mesenchymal stem cells (hMSCs). Load‐induced mechanotransduction, facilitated by the implant's architectural design, significantly amplifies hMSC differentiation.
