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 ...

Synthetic Hydrogels Incorporating Hydrolytic/Nonhydrolytic Macromer Ratios Exhibit Improved Tunability of In Vivo Degradation and Immune Responses

open access: yesAdvanced Healthcare Materials, EarlyView.
A synthetic 4‐arm maleimide‐terminated poly(ethylene glycol) (PEG‐4MAL) hydrogel system that combines hydrolytic ester‐linked macromer (PEG‐4eMAL) with nondegradable amide‐linked macromer (PEG‐4aMAL) in various stoichiometric ratios to tune the degradability rate. The macromers are crosslinked with dithiothreitol via thiol‐maleimide click reaction. The
