Biphasic Granular Bioinks for Biofabrication of High Cell Density Constructs for Dermal Regeneration
This study introduces a biphasic granular bioink (µInk) that enables 3D bioprinting of high cell density constructs for dermal regeneration. The bioink promotes cell proliferation, ECM deposition, and neovascularization, leading to tissue integration and reduced scar formation in vivo.

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 ...

Imiquimod‐loaded nanoparticles (PFSUV‐IMQ) are found to decrease liver metastasis and liver tumor burden when administered intravenously. Flow cytometry, RNA‐seq and various experiments show that the anti‐tumor response is immune‐mediated by activating dendritic cells resulting in increased CD8 T cell infiltration and activity.

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

Ultra‐Tiny Gelatin Nanoparticles‐Assisted 3D Stem Cell Spheroids for Engineering Tissue Regeneration
GNPs effectively guide the formation of structurally compact and functionally enhanced stem cell spheroids. This GNP‐assisted 3D culture system improves cell–cell and cell‐ECM interactions, leading to superior viability and complexity. Time‐dependent regenerative potential is demonstrated in both bone and skin defects, positioning GNP‐spheroids as a ...
