| Abstract | Diabetes mellitus affects millions of people in the world. Islet replacement strategies are becoming increasingly attractive options for patients at risk for severe diabetic complications. A major limitation of these approaches is the limited number of organs and the efficacy, safety and supply that restrict the available for islet transplantation. Recently, scientists have reported that stem cells promise a plentiful and flexible source for transplantation therapy. Here we used 10 ng/mL hepatocyte growth factor (HGF), 10 µM nicotinamide in PRMI 1640 to induce human embryonic germ cells (hEGCs) to differentiate into insulin producing cells. The results demonstrate that HGF and nicotinamide can promote the efficacy of insulin-secreting cells formation derived from embryoid bodies (EBs) derived hEGCs. The percentage of Dithizone (DTZ) positive, insulin, PDX-1, CK-19, Nestin positive in induced groups were significantly higher than the control. More importantly, levels of insulin-secreting after stimulation with high concentration glucose in inducing cells were significantly higher than the control (P<0.01). These results showed that cells derived from hEGCs expressed markers of definitive endoderm, pancreatic β cells, with the ability of glucose sensing and production of mature insulin. These cells integrated functions necessary for glucose responsive regulation of insulin in vitro. These findings suggest that hEGCs derivatives may eventually serve as a source of insulin producing cells for the treatment of diabetes. |

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.
