    • 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 α (HIF-1 α). 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.
    • 本发明提供了分离的骨髓样细胞群,其包含谱系阴性的大部分细胞,并表达CD44抗原,CD11b抗原和缺氧诱导因子1α(HIF-1α)。 当眼内施用于哺乳动物,特别是患有眼变性疾病的哺乳动物的眼睛时,这些细胞具有有益的血管营养和神经营养活性。 通过用针对CD44(透明质酸受体)的抗体对CD11b,CD14,CD33或其组合处理骨髓细胞,外周血细胞或脐带细胞来分离骨髓样细胞,并使用流式细胞术积极选择 CD44和/或CD11b表达细胞。 本发明的分离的骨髓样骨髓细胞可以用编码治疗有用的蛋白质的基因转染,用于将该基因递送至视网膜。

    • Transfected, mammalian, adult bone marrow-derived, lineage negative hematopoietic stem cell populations (Lin− HSCs) contain endothelial progenitor cells (EPCs) capable of rescuing retinal blood vessels and neuronal networks in the eye. Preferably at least about 20% of the cells express the cell surface antigen CD31. The transfected stem cells express an antiangiogenic fragment of tryptophanyl tRNA synthetase (TrpRS). The transfected Lin− HSC populations are useful for treatment of ocular vascular diseases and to ameliorate cone cell degeneration in the retina. In a preferred embodiment, the Lin− HSCs are isolated by extracting bone marrow from an adult mammal; separating a plurality of monocytes from the bone marrow; labeling the monocytes with biotin-conjugated lineage panel antibodies to one or more lineage surface antigens; removing of monocytes that are positive for the lineage surface antigens from the plurality of monocytes, and recovering a Lin− HSC population containing EPCs. The treatment may be enhanced by stimulating proliferation of activated astrocytes in the retina using a laser.
    • 转染的哺乳动物,成年骨髓来源的血清造血干细胞群体(含有HSCs)含有能够拯救眼睛中视网膜血管和神经元网络的内皮祖细胞(EPCs)。 优选地,至少约20%的细胞表达细胞表面抗原CD31。 转染的干细胞表达色氨酸tRNA合成酶(TrpRS)的抗血管生成片段。 转染的HSH-HSC群体可用于治疗眼血管疾病并改善视网膜中的锥细胞变性。 在一个优选实施方案中,通过从成年哺乳动物中提取骨髓来分离骨髓间充质干细胞; 从骨髓中分离多个单核细胞; 用与生物素缀合的谱系抗体对一种或多种谱系表面抗原标记单核细胞; 从多个单核细胞中除去对于谱系表面抗原呈阳性的单核细胞,以及回收含有EPCs的LINC-HSC群体。 可以通过使用激光刺激视网膜中活化的星形胶质细胞的增殖来增强治疗。
