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

open access: yesAdvanced 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.

Biofabrication of a Filtration Barrier by Integrating Electrospun Membranes and Flow in a Glomerular Co‐Culture

open access: yesAdvanced Healthcare Materials, EarlyView.
An ex vivo glomerular filtration barrier is engineered using electrospun, biomimetic membranes seeded with human glomerular cells. The model supports fenestrated endothelium and podocyte foot processes under flow, mimics size‐selective filtration, and enables disease modeling with hiPSC‐derived podocytes, offering a powerful platform for studying ...

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 ...

Low, but Physiological, Concentration of GLP-1 Stimulates Insulin Secretion Independent of the cAMP-Dependent Protein Kinase Pathway

open access: yesJournal of Pharmacological Sciences, 2008
Glucagon-like peptide-1 (GLP-1) induces pancreatic insulin secretion via the cAMP-dependent protein kinase (PKA) pathway. However, the GLP-1 concentration used in the previous in vitro experiments was far from the in vivo concentrations.

3D Bioprinted Renal Constructs Using Kidney‐Specific ECM Bioink System on Kidney Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
A kidney‐specific bioink derived from decellularized porcine kidney tissue supports the encapsulation, viability, and maturation of human primary kidney cells within 3D bioprinted constructs. In vivo, it also promotes the recruitment of host renal progenitor cells, collectively enhancing structural and functional regeneration of renal tissue.
