Engineering Anisotropic Mechanical Properties in Large‐Scale Fabricated Cartilage Constructs Using Microfiber Reinforcement

Advanced Healthcare Materials, EarlyView.
This study presents the development of large‐scale (15 cm2) cartilage constructs with anisotropic mechanical properties using melt electrowritten (MEW) microfiber reinforced cell‐laden gelatin methacryloyl (gelMA). These constructs mimic the mechanical behavior of native cartilage, providing a suitable environment for Articular Cartilage ...

Ultra‐Tiny Gelatin Nanoparticles‐Assisted 3D Stem Cell Spheroids for Engineering Tissue Regeneration

Advanced Healthcare Materials, EarlyView.
GNPs effectively guide the formation of structurally compact and functionally enhanced stem cell spheroids. This GNP‐assisted 3D culture system improves cell–cell and cell‐ECM interactions, leading to superior viability and complexity. Time‐dependent regenerative potential is demonstrated in both bone and skin defects, positioning GNP‐spheroids as a ...
