| Abstract | To characterize the fate of allogeneic neural stem cells (NSCs) following transplantation into injured spinal cord, green fluorescent protein (GFP)-NSCs isolated from GFP transgenic Sprague–Dawley rat embryos were transplanted into contused spinal cords of Wistar rats. The GFP-NSCs survived for at least 6 months in injured spinal cord; most of them differentiated rapidly into astrocytes, and a few were able to undergo proliferation. After transplantation, the GFP-NSCs remained in the transplantation site at the early stage, and then migrated along white-matter, and gathered around the injured cavity. At 6 months post-transplantation, CD8 T-lymphocytes infiltrated the spinal cord, and mixed lymphocyte culture from host and donor showed that lymphocytes from the host spleen were primed by allogeneic GFP-NSCs. At 12 months post-transplantation, most GFP cells in the spinal cord lost their morphology and disintegrated. The Basso, Beattie and Bresnahan score and footprint analysis indicated that the improvement of locomotor function in transplanted rats appeared only at the early stage, and was not seen even at 6 months after transplantation All these results suggest that the allogeneic NSCs, after transplantation into injured spinal cord, activate the host immune system. Therefore, if immunosuppressive agents are not used, the grafted allogeneic NSCs, although they can survive for a long time, are subjected to host immune rejection, and the effect of NSCs on functional recovery is limited. |

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.
