| Abstract | Hematopoietic stem cells (HSCs) are derived from endothelium in the aortic-gonado-mesonephric (AGM) region during embryogenesis. But little is known about whether endothelial progenitor cells (EPCs) retain hematopoiesis potential after birth. In this study, we isolated adult EPCs from the bone marrow of C57BL/6 mice and identified them with an endothelial functional assay and by the CD31(+) CD133(+) CD45(-/dim) VEGFR2(+) phenotype. EPCs isolated from green fluorescence protein (GFP) transgenic C57BL/6 mice were cotransfused with bone marrow cells from wild-type C57BL/6 mice into lethally irradiated BABL/c mice. One month after transplantation, granulocytes (25.73 ± 5.43%) and lymphocytes (12.68 ± 3.26%) in peripheral blood showed GFP(+), referred to as donor EPC-derived blood cells. After an additional month, the percentage of GFP(+) granulocytes decreased to (3.69 ± 1.43%), whereas the percentage of GFP(+) lymphocytes showed no significant difference. Most of the GFP(+) elements showed a diffuse distribution in the spleen; but some were present as aggregates forming lymphoid nodules. GFP(+) endothelial cells were observed in the liver sinusoids, intestinal villi, and lung of recipient mice. These results indicated that adult EPCs not only took part in vasculogenesis, but also retained hematopoietic ability. |

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.
