摘要
The present invention provides an isolated myeloid-like cell population comprising a majority of cells that are lineage negative, and which express both CD44 antigen, CD11b antigen, and hypoxia inducible factor 1 (HIF-1 ). These cells have beneficial vasculotrophic and neurotrophic activity when intraocularly administered to the eye of a mammal, particularly a mammal suffering from an ocular degenerative disease. The myeloid-like cells are isolated by treating bone marrow cells, peripheral blood cells or umbilical cord cells with an antibody against CD44 (hyaluronic acid receptor), against CD11b, CD14, CD33, or against a combination thereof and using flow cytometry to positively select CD44 and/or CD11b expressing cells therefrom. The isolated myeloid-like bone marrow cells of the invention can be transfected with a gene encoding a therapeutically useful protein, for delivering the gene to the retina.
