| Abstract | A number of medical conditions including hematopoietic stem cell malignancies, immunodeficiencies, and autoimmune diseases can be treated using bone marrow cells. However, the major hindrance to the routine use of bone marrow cells is their unparalleled immunogenicity, requiring the use of harsh and toxic preconditioning regimens that can be fatal. Thus, identification of a safer alternative source of hematopoietic stem cells that can be broadly used in such therapies is highly desirable. Despite the current limited number of human ES cell lines, we believe that the newer technology of reprogramming adult somatic cells into pluripotent cells will eventually lead to greater availability of stem cell lines. Even more compelling is the possibility to directly reprogram a somatic cell into another adult cell type of a different tissue without the need for generating pluripotent cells. Here, I will discuss the immunological properties of mouse ES cell-derived hematopoietic progenitor cells. These progenitor cells poorly express MHC class I antigens but are responsive to stimulation by IFN-γ and other cytokines. However, despite upregulating MHC class I antigens after stimulation, they do not express class II molecules, a consequence of their lack of expression of the critical class II transcription factor CIITA. In this overview, I will discuss some of the published data on antigenicity and immunogenicity of ES cell-derived tissues. As more cells and tissues derived from ES cells become available for transplantation, we will gain more insight and into their abilities to interact with immune cells. |

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.
