| Abstract | Vascular niche plays a critical role in regulating the cellular phenotypes in cells around the niche. Because physiological parameters (e.g., flow & pressure) directly influences the functional status of vasculature, which then influence the surrounding cellular phenotypes, it is essential to study cell behaviors in a realistic, physiologically relevant system in order to better understand the interactions between the surrounding cells and the vascular niche. Here we report the design and construction of a dynamic flow co-culture system in which vascular cells and the surrounding cells can be co-cultured in the system and allowed to communicate with each other via soluble factors and cell-cell contact. The system is able to accurately replicate any pre-defined shear stress waveform and apply it to the cultured vascular cells. To validate the performance of the system, an investigation of the reaction of human umbilical vein endothelial cell (HUVEC) co-cultured with human smooth muscle cells to different shear stress environments is presented. Further investigation includes the effects of the different resulting HUVEC gene expression on cell types that are found adjacent in the vascular niche to the surrounding cells such as smooth muscle cell (SMC). A procedure was developed to provide consistent results when applying the shear force that match in vivo conditions... Overall cell morphology, alignment, growth proliferation, and RNA expression are reported of both cell lines. |

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.
