| Abstract | In this study, the tissue distribution and accumulation of osteocalcin or bone Gla protein (BGP) and matrix Gla protein (MGP) were determined during tooth development in a teleost fish, Argyrosomus regius. In this species, the presence of BGP and MGP mRNA in teeth was revealed by in situ hybridization. mRNA for BGP was detected in the odontoblasts as well as in its cytoplasmic processes emerging through dentinal tubules, while mRNA for MGP was expressed in the enamel portion within the apical portion of the elongated cell bodies of enameloblasts, adjacent to the root of the teeth as well as in cells within the pulpal space. Immunolocalization of BGP and MGP demonstrated that these proteins accumulate mainly in the mineralized dentin or in enameloblastic processes, confirming in situ hybridization results. In this study, we examined for the first time the localization of both BGP and MGP gene expression and protein accumulation within the different regions of the vertebrate tooth. We clearly demonstrated that although the overall pattern of BGP and MGP gene expression and protein accumulation in A. regius teeth was in general agreement to what is known for other vertebrates such as rats or rodents, our study provided novel information and highlighted some species-differences between fish and higher vertebrates. |

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.
