| Abstract | Most parthenogenetic embryos (PEs) in mammals die shortly after implantation, and this failure to develop is associated with genomic imprinting. We have examined the influence of human recombinant basic fibroblast growth factor 2 (FGF-2) and human recombinant insulin-like growth factor II (IGF-II) on the development of (CBA×C57BL/6)F1 parthenogenetic mouse embryos. Embryos were treated in vitro at the morula stage with different doses of FGF-2 and, after their development to blastocysts, transferred to pseudopregnant recipients. The optimal doses of FGF-2 did not affect the number of forming and implanting blastocysts, but increased, from 20 to 42%, the number of embryos developing to somite stages. PEs (18–21 somites) treated with an optimal dose of FGF-2 were explanted for further development in culture by treatment with the second growth factor, IGF-II. Eighty-three percent of those embryos cultured with IGF-II (2.5 μg/ml) developed to 35 or more somites, as compared with 36% of embryos cultured without any growth factors (P<0.01). Also, a significantly higher proportion of PEs developed to 40–50 somites in this case. These results show that the in vitro treatment of PEs with FGF-2 at the morula stage increases the number of somite embryos, and the second treatment of somite PEs with IGF-II in culture medium prolongs their development significantly. |

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.
