| Abstract | Wound healing and the grow-in of free tissue grafts critically depend on blood vessel growth, i.e., on the angiogenic invasion of endothelial cells, which is critically reduced in smokers, in patients suffering from microangiopathies (e.g., in diabetes), or in those who are treated with immunosuppressives. Although several angiogenic factors have been tested to accelerate wound healing in such critically patients, their combinations have not yet been systematically investigated. This study was done to reveal which combination of proangiogenic with promaturating factors is the most effective in an endothelial wound closure assay. Human umbilical vein endothelial cells were isolated, cultured to confluence, and subjected to a scratch wound assay with the addition of vascular endothelial growth factor (VEGF)-A(165), platelet-derived growth factor (PDGF)-AB, angiopoietin-1 (ANG1), or ANG2 and all of their 16 possible combinations. VEGF-A(165) plus ANG1 was most effective at accelerating endothelial scratch closure. Moreover, VEGF-A(165) stimulated wound closure in all combinations tested, while it was attenuated by PDGF-AB. Thus, with respect to their effects on endothelial cells, a combination of VEGF-A with ANG1 is the most promising and is superior to combinations with PDGF-AB. |

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.
