A Novel Core–Shell Hydrogel 3D Model for Studying Macrophage Mechanosensing and Foreign Body Giant Cell Formation

Advanced Healthcare Materials, EarlyView.
The foreign body response (FBR) to biomaterials is primarily driven by macrophages, which often fuse into destructive foreign body giant cells (FBGCs). To address the limited understanding of FBGC formation, a novel microscale core–shell hydrogel 3D model is developed using heterogeneous alginate‐collagen microcapsules with varying stiffness, offering ...

Programmable Compliance in Small‐Diameter Vascular Grafts by Design of Melt‐Electrowritten Scaffold Architectures for In Situ Tissue Engineering

Advanced Healthcare Materials, EarlyView.
Small‐diameter vascular grafts with compliance tunable by design are fabricated via melt electrowriting. By controlling the winding angle of intertwined helical fibers, grafts with compliances matching those of human vessels, from veins to arteries, are realized. This holds the potential of avoiding a compliance mismatch, which has been identified as a

Introduction to Prosthetic Limbs [PDF]

, 2015
Approximately 2 million people in the Unites States alone have had an amputation, and many of these people use a prosthetic limb daily. The prosthetic limb, which began as a primitive device, is now a highly sophisticated piece of technology.
