| Abstract | A cell population with characteristics of multipotent mesenchymal stromal cells (MMSCs) was isolated from human subcutaneous adipose tissue (SAT) submitted to a deep freezing (at −70°C) without cryoprotector. Under critical conditions for tissue, the cells retained their viability in vitro and were adhesive to plastic. The cell population was characterized by homogeneity and was represented by small cells (7 μm in diameter) with fibroblast-like morphology. The cytofluorimetric analysis of the cells revealed the presence of antigens on their surface whose expression is characteristic of MMSCs, including CD29, CD44, CD49a,b,d, CD73, CD90, CD105, CD166, and HLA ABC. The cells were negative for CD34, CD45, which are markers of hematopoietic cells; CD31, a marker of endothelial cells; and Stro-1, as well as antigens of the major histocompatibility complex of the II class HLA DR, DP, and DQ. On average, the proportion of cells that carry the receptor of the stem-cell factor c-kit (CD117) amounted to 3%. Upon induction to differentiation in vitro, these cells turned out to be able to form cells similar to cells of bone, adipose, and cartilage tissues. Karyological analysis (GTG staining method) demonstrated the diploid set of chromosomes of cells, without aneuploidy and structural reconstruction of chromosomes. Thus, it has been established that, in SAT submitted to low-temperature shock, a viable population of cells with a phenotype similar MMSCs is preserved. |

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.
