| Abstract | The goal of this study was to conduct a comparative analysis of the degree of resistance to low temperatures of human epidermal cells found at different stages of differentiation. The action of liquid-nitrogen vapors was analyzed in experiments in vitro at various temperature regimes on fragments of the human integral skin and on isolated from them and cultivated keratinocytes. The degree of resistance of keratinocytes to the action of cooling to low temperatures was evaluated by their ability to form a multilayer stratum in culture, which indicates the preservation of the viability of the cells treated with cold. This approach allowed one to reveal the diapason of optimal regimes of the action of low temperatures on cells in the composition of tissue and after their conversion into culture. The quantitative ratios of the epidermal stem, transitory, and differentiated cells in a population of viable cells before and after exposure to low temperatures were determined with antibodies that correspond to their different stages of differentiation. The degree of resistance of keratinocytes to action of cooling to low temperatures was evaluated by their ability to form a multilayer stratum in culture, which indicates preservation of viability of the cells treated with cold. The results of this study show that the resistance of human epidermal cells to low temperature differs depending on their stage of differentiation both in situ and in vitro. The epidermal stem and transitory cells are more stable than the differentiated cells. |

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.
