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

Advanced 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 ...

Animal‐Free Setup of a 3D Mature Adipocyte‐Macrophage Co‐Culture to Induce Inflammation In Vitro

Advanced Healthcare Materials, EarlyView.
A completely animal‐free 3D co‐culture is developed using human fat cells and immune cells. Animal‐based materials are replaced with gellan gum hydrogel and a serum‐free medium. Immune cells are effectively activated, producing specific inflammatory signals.

Magnetic‐Driven Torque‐Induced Electrical Stimulation for Millisecond‐Scale Wireless Neuromodulation

Advanced Healthcare Materials, EarlyView.
MagTIES is a wireless neuromodulation technique with millisecond precision. It employs magnetic‐driven torque from magnetite nanodiscs to activate piezoelectric nanoparticles, enabling precise temporal control of neuronal activity and brain oscillations using weak, low‐frequency magnetic fields.

Permeation Enhancer‐based Ionogel Shows Remarkable Potential for Oral Insulin Delivery

Advanced Healthcare Materials, EarlyView.
This study proposes a novel formulation of decanoate in an ionic liquid inspired drug delivery system. The formulation demonstrates ideal physicochemical and material properties for oral peptide delivery. Findings indicate that choline decanoate (1:2 molar ratio) forms a viscoelastic gel that enables high oral bioavailability of insulin in rats ...
