Abstract: The invention generally provides compositions and methods for promoting and enhancing wound closure and healing. Specifically, the invention provides a biologic composition which comprises a support layer which serves as transport scaffold, for example made of gelatin, which is coated or impregnated with a bio-adhesive molecule such as rose bengal or glyceraldehyde. The composition can also comprise an artificial or biological matrix, optionally processed (i.e. cleaned and coated with extracellular matrix proteins) to enhance cell attachment and survival. The composition can further comprise a monolayer of epithelial, endothelial cells or mesenchymal cells. The invention provides methods for using the compositions for treating wounds due to disease, trauma or surgery. Specific methods for treating ocular wounds are provided.

Abstract: The invention is directed to compositions and methods for reversing age-related changes in extracellular matrix proteins, particularly the collagen framework of basement membranes of various organs. The invention has particular application to age-related changes that impair Retinal Pigment Epithelium (RPE) cell repopulation of human Bruch's membrane.
