Mechanical Reinforced and Self‐healing Hydrogels: Bioprinted Biomimetic Methacrylated Collagen Peptide‐Xanthan Gum Constructs for Ligament Regeneration

Advanced Healthcare Materials, EarlyView.
Readily UV‐curing and self‐healing methacrylated collagen peptide (COPMA) hydrogels are developed with tunable mechanical properties. As the interpenetrating network between COPMA and xanthan gum (XG), COPMA‐XG bioinks show improved mechanical properties, printability, and stability, compared to COPMA or XG.

3D Bioprinting‐Assisted Engineering of Stem Cell‐Laden Hybrid Biopatches With Distinct Geometric Patterns Considering the Mechanical Characteristics of Regular and Irregular Connective Tissues

Advanced Healthcare Materials, EarlyView.
A hybrid biopatch platform integrating 3D printed polymeric patterns with stem cell‐laden collagen bioinks is developed to mimic the mechanical properties of connective tissues. By tailoring geometric architectures, the constructs replicate anisotropic or isotropic mechanics, enhancing tissue‐specific regeneration.

Geometrically Controlled WNT Activation Drives Intestinal Morphogenesis

Advanced Healthcare Materials, EarlyView.
Crypt‐villi‐like morphogenesis can be driven and controlled via architectural patterns in colorectal cells with the use of digital light processing printing. The resulting mini tissues exhibit budding structures and functionality, as evidenced by increased mucin expression.

Hydrogel‐Mediated Preservation of Live Tumor Explants for Drug Development in Peritoneal Metastases

Advanced Materials, EarlyView.
This study presents a hyaluronan‐based hydrogel platform preserving the native tumor microenvironment (morphology, tissue composition, histology) of patient‐derived explants from peritoneal metastases, enabling clinically relevant drug screening. Hydrogel properties such as stiffness and degradation are crucial for longer‐term histoculture.
