Abstract
Described herein are placental tissue grafts produced by chemical dehydration followed by freeze-drying the placental tissue to produce the tissue graft. The tissue grafts retain their biological properties preferably at the same level as the placental tissues before they are processed. The placental tissue grafts have numerous medical applications. Methods for making the tissue graft compositions are also described herein.
