Overcoming foreign-body reaction through nanotopography: Biocompatibility and immunoisolation properties of a nanofibrous membrane

From Micro to Macro: The Hierarchical Design in a Micropatterned Scaffold for Cell Assembling and Transplantation

A microwell-patterned membranous scaffold that integrates nano- and microscale topographical characteristics based on polyurethane is fabricated for transplanting syngeneic islets and allogeneic mesenchymal stem cells into diabetic rodents. The scaffold effectively allows for assembling of single cells/microtissues, enables the transplantation of cells with spatial control, and improves the transplant's engraftment efficacy in vivo for treating diabetes.

A bio-inspired high strength three-layer nanofiber vascular graft with structure guided cell growth

A bio-inspired three-layer vascular graft with strong mechanical properties and good cell biocompatibility was fabricated by electrospinning. It will play an important role in vessel remodeling and regeneration.
