Abstract
Methods and compositions for treating and reducing retinal degeneration using progenitor cells and conditioned media from progenitor cells, such as postpartum-derived cells are disclosed. Trophic factors and other agents secreted by the progenitor cells that protect retinal cells and inhibit apoptosis of retinal cells such as photoreceptor cells are also disclosed.

- 2. A method of administering a population of postpartum-derived cells to the eye of a subject, wherein the cell population secretes bridge molecules, and wherein the bridge molecules are selected from MFG-E8, Gas6, TSP-1 and TSP-2.
- 10. A method of reducing retinal cell oxidative damage comprising administering to the eye of a subject a population of postpartum-derived cells or a conditioned medium generated by culturing the postpartum-derived cells, wherein the postpartum-derived cells are isolated from human umbilical cord tissue substantially free of blood.
- 11. A method of rescuing retinal pigment epithelial (RPE) cell dysfunction in retinal degeneration, the method comprising administering to the eye of a subject a population of postpartum-derived cells, wherein the postpartum-derived cells are isolated from human umbilical cord tissue substantially free of blood, wherein the cell population secretes bridge molecules, and wherein the bridge molecules are selected from MFG-E8, Gas6, TSP-1 and TSP-2.
- 12. A method for reducing the loss of photoreceptor cells in retinal degeneration, the method comprising administering to the eye of a subject a population of postpartum-derived cells in an amount effective to reduce the loss of photoreceptor cells, wherein the postpartum-derived cells are isolated from human umbilical cord tissue substantially free of blood, wherein the population of postpartum-derived cells secretes bridge molecules, and wherein the bridge molecules are selected from MFG-E8, Gas6, TSP-1 and TSP-2.
- 16. A method for reducing the loss of photoreceptor cells in retinal degeneration comprising administering to the eye of a subject a composition comprising a population of postpartum-derived cells, wherein the composition is administered in an amount effective to reduce the loss of photoreceptor cells, wherein the postpartum-derived cells are isolated from human umbilical cord tissue substantially free of blood, wherein postpartum-derived cells secrete bridge molecules, and wherein the bridge molecules are selected from MFG-E8, Gas6, TSP-1 and TSP-2.
