| Abstract | Postnatal bone marrow contains a subtype of unique progenitor cells that have the capacity to differentiate into functional endothelial cells. Hence, these cells have been termed endothelial progenitor cells (EPCs). In general, circulating EPCs were characterized by the expression of CD133, CD34 and the vascular endothelial growth factor receptor-2 (VEGFR2). Recent data have additionally described some CD14(+/low) myeloid subsets as functional endothelial precursors. Convincing evidence in vivo has further emerged that the vascular homing of EPCs contributes to endothelial regeneration thereby limiting neointimal hyperplasia after arterial injury. However, in the context of primary atherosclerosis, plaque progression and destabilization, injection of EPCs as well as application of stem-cell mobilizing factors have been shown to correlate with conversion to unstable plaque phenotype. Clinically, the number and function of EPCs have been positively linked with an improved endothelial function or regeneration but frequently inversely correlated with cardiovascular risk (factors). Thus, considering the dual contribution of EPCs in vascular repair and remodeling in primary atherosclerosis versus arterial injury and identifying mechanisms for selective control of their recruitment appears crucial to improve prediction and to directly modulate endogenous vascular homeostasis. |

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.
