A method of treating hypoxic tissue such as wound tissue comprises contacting a composition to the hypoxic tissue in a hypoxia-treatment effective amount, the composition comprising a biodegradable polymer and an inorganic peroxide incorporated into the polymer.

Oxygen-generating compositions for enhancing cell and tissue survival in vivo

Provided herein are scaffolds and methods useful to promote the formation of functional clusters on a tissue, for example, motor endplates (MEPs) or a component thereof on skeletal muscle cells or tissue, as well as the use of scaffolds so produced for repairing a tissue injury or defect.

Bioscaffolds for formation of motor endplates and other specialized tissue structures

Microcapsules are described that comprise (a) a liquid aqueous or hydrogel core; (b) a semipermeable membrane surrounding said core; (c) live animal cells (e.g., pancreatic cells) in the core; and (d) oxygen-generating particles in said core, said oxygen-generating particles included in said microcapsules in an amount sufficient to lengthen the duration of viability of said animal cells in said microcapsules. Compositions comprising such microcapsules and uses thereof, such as in treating diabetes, are also described.

Co-encapsulation of live cells with oxygen-generating particles

A topical wound treatment composition comprises a hydrogen peroxide generator; alkaline powder; not more than 5 percent by weight of water; additional topical active agent if desired, and emollient (preferably hygroscopic emollient) to balance. When topically applied to a wound and water from the surrounding environment diffuses into the composition, the hydrogen peroxide generator and/or the alkaline compound diffuse into one another, causing a chemical reaction that generates treatment-effective amounts of oxygen to occur. The oxygen can then diffuse out of the composition and aid in wound treatment or healing.

Topical wound treatment method and composition

A composite for delivering extended-release of oxygen is disclosed. The composite can include a biocompatible polymeric support having a plurality of solid peroxide particles suspended therein. The polymer support can exhibit an oxygen tension value of at least 40 mmHg for a period of 14 days. The weight ratio of biocompatible polymeric support to solid peroxide particles can range from 1:1 to 99:1. Also disclosed is a method of using the composite to deliver oxygen to cells in both in vivo and in vitro environments.
