A Novel Microfluidic System for 3D Epidermis and Full‐Thickness Skin Growth for Nanoparticle Safety Assessment

open access: yesAdvanced Healthcare Materials, EarlyView.
This work presents a novel, dynamically perfused, configurable microfluidic system for epidermis‐only (E and full‐thickness skin (FT SoC) growth, emulating human skin structure and barrier function. Upon TiO2 nanoparticle exposure, the system reveals compromised barrier integrity, reduced metabolic activity, increased permeability, and chemokine‐driven

A Microphysiological Interface of Skeletal Myobundles and Inflamed Adipose Tissue for Recapitulating Muscle Dysfunction in an Obese Microenvironment

open access: yesAdvanced Healthcare Materials, EarlyView.
A human cell‐based microphysiological system integrates engineered muscle tissues with an inflamed adipose–macrophage niche to model obese microenvironment‐induced muscle dysfunction. Muscle contraction is quantified by pillar deflection coupled with computational stiffness estimation. Secretome and transcriptomic profiling reveal inflammation‐mediated
