| Abstract | Mouse and human fibroblasts have been transformed into induced pluripotent stem (iPS) cells by retroviral transduction or plasmid transfection with four genes. Unfortunately, viral and plasmid DNA incorporation into chromosomes can lead to disruption of gene transcription and malignant transformation. Tumor formation has been found in offspring of mice generated from blastocysts made mosaic with iPS cells. To proceed with iPS cells for human therapy, reprogramming should be done with transient gene expression. Recently, adenoviral vectors have been used to produce mouse iPS cells without viral integration. Here, we report the successful creation of human iPS cells from embryonic fibroblasts using adenoviral vectors expressing c-Myc, Klf4, Oct4, and Sox2. After screening 12 colonies, three stable iPS cell lines were established. Each cell line showed human embryonic stem cell morphology and surface markers. Southern blots and polymerase chain reaction demonstrated that there was no viral DNA integration into iPS cells. Fingerprinting and karyotype analysis confirmed that these iPS cell lines are derived from the parent human fibroblasts. The three human iPS cell lines can differentiate to all three germ layers in vitro, including dopaminergic neurons. After s.c. injection into nonobese diabetic-severe combined immunodeficient mice, each human iPS line produced teratomas within 5 weeks postimplantation. We conclude that adenoviral vectors can reprogram human fibroblasts to pluripotent stem cells for use in individualized cell therapy without the risk for viral or oncogene incorporation. |

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.
