| Abstract | PURPOSE: The neovascular form of age-related macular degeneration (AMD) is characterized by the growth of abnormal new blood vessels from the choroid, termed choroidal neovascularization (CNV). The origin of the new vessels in CNV, however, has not been elucidated fully to our knowledge. The purpose of this study is to identify vascular endothelial side population (SP) cells in the preexisting choroidal vessels, and investigate their potential role in AMD. METHODS: We made single cell suspensions of freshly isolated mouse choroidal, retinal, and brain tissue by enzymatic digestion. Vascular endothelial SP cells were isolated using flow cytometry based on the ability to efflux the DNA-binding dye, Hoechst 33342, via ATP-binding cassette (ABC) transporters. RESULTS: In the choroid, 2.8% of CD31â ºCD45â » vascular endothelial cells (ECs) showed a typical SP staining pattern. They were not bone marrow-derived and possessed high colony-forming capacity in vitro. They proliferated during laser-induced CNV in vivo. In contrast, stereotypic SP staining pattern was not observed in retinal and brain ECs. Retinal and brain EC-SP cells included increased SP populations with less colony-forming capacity within the SP compartment, because they contained cells with and without proliferative potential. The latter still could efflux the dye due to high levels of ABC transporters, such as ABCB1a, ABCC4, and ABCC6. CONCLUSIONS: The EC-SP cells in the choroid may represent vessel-residing endothelial stem/progenitor cells contributing mainly to angiogenesis, and may be useful for augmenting vascular regeneration or for developing new antiangiogenic therapy in AMD. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
