| Abstract | PURPOSE: The application of lacrimal gland-derived mesenchymal stem cells (LG-MSC) for the regeneration of lacrimal gland tissue could result in a novel therapy for dry-eye syndrome. To optimize the culture conditions, the purpose of this study was to evaluate the influence of low oxygen on phenotype, differentiation potential, proliferative, and regenerative capacity of murine LG-MSC. METHODS: Murine LG-MSC were cultured in 21% and 5% oxygen and characterized by flow cytometry, cell sorter assisted proliferation-, and colony forming unit-assays. Reactive oxygen species (ROS) levels as well as lineage differentiation were evaluated. The effect of conditioned medium of LG-MSC from both oxygen conditions (CM MSC 21%, respectively, CM MSC 5%) on lacrimal gland epithelial cells (LG-EC) was examined in wound healing and proliferation assays. RESULTS: Cells under both culture conditions revealed differentiation potential and presented a MSC-specific flow cytometric phenotype. In 5% oxygen, cells yielded less ROS, showed a stable morphology, higher colony forming potential, and an increased proliferation capacity. Five percent oxygen significantly increased the number of CD44+ LG-MSC. Furthermore, CM MSC 5% significantly enhanced migration and proliferation in LG-EC. CONCLUSIONS: In vitro expansion in low oxygen preserves the proliferation capacity and differentiation potential of LG-MSC and increases the effects of conditioned medium on migration and proliferation in LG-EC. Therefore, expansion in low oxygen seems to be an excellent method, to obtain vital MSC. Also, an increased number of LG-MSC expressing CD44 was observed under low oxygen, which might be a valuable marker to identify a potent MSC subpopulation. |

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.
