| Abstract | Endometrial stem cells provide a readily accessible source of adult stem cells suitable for various stem cell based therapies. The first essential step in the process of stem cell isolation, sorting and culture is tissue dissociation into single cell suspension. Tissue dissociation efficiency determines the number of resulting viable cells which in turn could affect the feasibility of the subsequent stem cell application. Microfluidic based platforms could provide several advantages over current conventional tissue dissociation techniques (e.g. mechanical or enzymatic or both) and help the optimization of the process towards a better reproducible cellular outcome. Objective: To develop a simple miniaturized platform for endometrial tissue dissociation which can be used to evaluate and optimize experimental conditions necessary for producing single cell suspension with minimal cell damage. Methods: A Poly-DiMethylSiloxane (PDMS) channel microfluidic platform was designed. The platform includes a tissue dissociation chamber where raw endometrial tissue was incubated. Trypsin was delivered through an inlet channel while another inlet enabled parallel delivery of a cell suspension medium and an outlet channel received the downstream dissociated endometrial cells. A cell size based filtration step is designed to trap large debris using two rows of posts. A viability stain is used to test the viability of cells produced at different enzyme-tissue contact durations. Conclusion: We present a simple microfluidics based platform for endometrial tissue dissociation that can be used for subsequent endometrial stem cell research applications and can be further applied to other tissues. |

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.
