Coated Blood Vessels Reduce Transplant Rejection

When patients undergo organ transplants, ensuring their bodies don't reject the foreign implants is of the utmost importance. Blood vessels in organs are naturally protected by a coating of sugars that suppress reactions from immune systems, but these sugars are damaged in the process of procurement for transplantation. A recent SciTechDaily article discussed a new method for preventing organ transplant rejection, and it involves coating the blood vessels with a special polymer that mimics the missing protective sugars.
