| Abstract | The Ca2+-dependent cell-cell adhesion system (CDS) is thought to be essential for the formation and maintenance of cell adhesion in a wide variety of tissues. Previous studies suggested that CDS has some cell-type specificity; for example, the monoclonal antibody ECCD-1 selectively recognizes CDS of certain epithelial tissues in mouse embryos but not nervous tissues. In the present study, we have obtained a monoclonal antibody, designated NCD-1, that disrupts connections between brain cells of mouse embryos. A series of experiments suggested that NCD-1 specifically recognizes CDS. We then determined the distribution of the NCD-1 antigen in various mouse tissues. NCD-1 reacted with cells of the following tissues and cell lines: nervous tissues from various sources, lens, striated muscle, cardiac muscle, glioma G26-20, adrenocortical tumor Y1, and melanoma B16. None of these cells reacted with ECCD-1, and the cells reactive with ECCD-1 did not react with NCD-1. There was also a class of cells that did not react with either ECCD-1 or NCD-1. These results suggest that cells in the body can be classified into at least three groups containing CDS of differing specificities. A map of the tissue localization of these different classes of CDS also suggests that the expression of cell-type-specific cell adhesion molecules in each tissue plays a crucial role in adhesion between the same cell types and segregation of different cell types in processes essential for animal morphogenesis. |

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.
