    • Isolated, 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 in the isolated Lin- HSCs express the cell surface antigen CD31. The isolated Lin- HSC populations are useful for treatment of ocular vascular diseases. 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. Isolated Lin- HSCs that have been transfected with therapeutically useful genes are also provided, and are useful for delivering genes to the eye for cell-based gene therapy. Methods of preparing isolated stem cell populations of the invention, and methods of treating ocular diseases and injury are also described.
    • 分离的,哺乳动物,成年骨髓来源的谱系负造血干细胞群(Lin-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,分离的Lin-HSC中至少约20%的细胞表达细胞表面抗原CD31。 分离的Lin-HSC群体可用于治疗眼血管疾病。 在优选的实施方案中,通过从成年哺乳动物提取骨髓来分离Lin-HSC; 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EPC的Lin-HSC群体。 还提供已经用治疗有用的基因转染的分离的Lin-HSC,并且可用于将基因递送到眼中用于基于细胞的基因治疗。 还描述了制备本发明的分离的干细胞群体的方法,以及治疗眼部疾病和损伤的方法。
