Abstract
Described herein are tissue grafts produced by contacting dehydrated placental tissue grafts with a cross-linking agent. The tissue grafts described herein provide barrier and prevent the migration of a bioactive agent from the wound. Thus, the tissue grafts enhance wound healing while preventing the undesirable migration of a bioactive agent from the wound. Methods for making and using the cross-linked grafts are also described herein.
