This document provides amnion tissue preparations (e.g., compositions including an amnion tissue preparation) and methods for using amnion tissue preparations. In some cases, amnion tissue preparations can be used for treating a mammal (e.g., a human) having one or more tumors. For example, embolic agents including an amnion tissue preparation (e.g., amnion coated embolic agents) that can be used in arterial embolization to reduce or eliminate blood flow in a blood vessel that supplies a tumor are provided. In some cases, amnion tissue preparations can be used for treating a mammal (e.g., a human) having one or more wounds and/or skin disorders. For example, compositions including an amnion tissue preparation formulated for transdermal delivery that can be used to treat wounds and/or skin disorders are provided.
