Conditioned Media from Mechanically Stimulated Macrophages Upregulate Osteogenic Genes in Human Mesenchymal Stromal Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Bone fracture healing is a complex, timely orchestrated scenario involving multiple cell types and a plethora of cytokines and regulatory factors. To gain further insight, an in vitro model to a) study macrophage polarization under mechanical load in a fibrin hydrogel and b) subsequently assess the effect of conditioned media derived from macrophages ...

Dissolving Microneedle for Maintaining the Integrity of HPV Virus‐Like Particles Enabling Durable Sterile Protection Across Various Mucosal Tissues

open access: yesAdvanced Healthcare Materials, EarlyView.
A novel dissolving microneedle platform preserves HPV virus‐like particle (VLP) immunogenicity by maintaining structural integrity, crucial for eliciting potent immune responses. Buccal administration induces robust immune response, high neutralizing antibody titers, and durable sterile protection across oral and vaginal mucosal sites.

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.

Suppressing t(4;11) Acute Leukemia by Lipopolymer Nanoparticle Delivery of siRNA Targeting KMT2A::AFF1 with Enhanced Extrahepatic Delivery

open access: yesAdvanced Healthcare Materials, EarlyView.
This study introduces a new lipopolymer nanoparticle (LPNP) system that efficiently delivers siRNA to leukemia cells. The LPNPs silence the leukemia fusion gene KMT2A::AFF1, induce apoptosis, and decrease leukemia burden in mice. These results demonstrate the potential of LPNPs as a targeted siRNA therapy for acute lymphoblastic leukemia.

Coordinated Development of Immune Cell Populations in Vascularized Skin Organoids from Human Induced Pluripotent Stem Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Vascularized skin organoids are developed from human induced pluripotent stem cells and contain macrophages, Langerhans cells, and neutrophils. Vascularized skin organoids offer a transformative platform to model skin biology and enable mechanistic investigations of inflammatory and hematologic skin disorders.
