| Abstract | A method for the in vitro proliferation of human bone marrow mesenchymal stem cells (MSCs) employing a medium not containing fetal calf serum (FCS) was developed for a regenerative medicine of cartilage using MSCs. Without using density-gradient centrifugation, the bone marrow aspirate was poured into a dish (6.0 \times 105 nucleated cells/cm2) with DMEM medium containing 10% serum (FCS or donor serum) and basic fibroblast growth factor, and incubated at 37 °C under a 5% CO2 atmosphere. The density of adhesive cells incubated with the medium containing human serum and basic fibroblast growth factor (10 ng/ml) almost reached confluence at 19d and was 1.4-2.7 times that in the medium containing only FCS. The density of cells incubated with the medium containing only human serum was 0.1-0.6 times that in the medium containing only FCS. The content of CD45- CD105+ cells among the cells harvested after a 19-d incubation in the medium containing human serum and basic fibroblast growth factor was higher than 90%. This high content and chondrogenic activity, which was confirmed by pellet cultivation and staining with Safranine O, were maintained even after further subcultivation in the medium to 17 population doubling levels. Consequently, this method might be applicable to in vitro proliferation of MSCs for the regeneration of cartilage. |

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.
