Therapeutic Implants: Mechanobiologic Enhancement of Osteogenic, Angiogenic, and Myogenic Responses in Human Mesenchymal Stem Cells on 3D‐Printed Titanium Truss

Advanced Healthcare Materials, EarlyView.
This study investigates a synergistic effect between 3D‐printed surface features and mechanical micro‐strain in enhancing the osteogenic, angiogenic, and myogenic responses of human mesenchymal stem cells (hMSCs). Load‐induced mechanotransduction, facilitated by the implant's architectural design, significantly amplifies hMSC differentiation.

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.
