Bioassembly of Region‐Specific Fibrocartilage Microtissues to Engineer Zonally Defined Meniscal Grafts

open access: yesAdvanced Healthcare Materials, EarlyView.
Meniscal microtissues are fabricated using progenitor cells isolated from the inner (iMPCs) and outer (oMPCs) regions of the meniscus. Meniscal microtissues fuse into cohesive constructs rich in sGAG and collagen. cABC treatment modulates collagen fiber formation and organization in assembled grafts.

Engineering Volumetric Tissue Analogs via Assembly of Endothelial Cell‐Covered Spheroidal Microtissues

open access: yesAdvanced Healthcare Materials, EarlyView.
An engineering strategy to fabricate highly vascularized volumetric tissues with capillary networks is developed. Endothelial cell‐covered spheroidal microtissues with high structural integrity are efficiently produced using bioprinting technology. These spheroidal microtissues are then assembled and cultured under perfusion conditions, resulting in ...

A Patient‐Specific 3D Printed Carotid Artery Model Integrating Vascular Structure, Flow, and Endothelium Responses

open access: yesAdvanced Healthcare Materials, EarlyView.
This study introduces the first miniaturized, patient‐specific carotid artery model created via 3D printing using GelMA with embedded vascular cells. Combining CFD, PIV, and flow perfusion, the model replicates anatomically dependent hemodynamics and cellular responses.

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
