Microphysiological Systems for Comorbidity Studies: Chronic Kidney Disease and Osteoarthritis

Advanced Healthcare Materials, EarlyView.
This review highlights the potential of organ‐on‐a‐chip systems for studying comorbidities, using chronic kidney disease (CKD) and osteoarthritis (OA) as examples. It summarizes recent advances in kidney‐on‐a‐chip and joint‐on‐a‐chip models and discusses their current and potential application in investigating CKD, OA, and CKD‐OA comorbidity, aiming to

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 ...
