| Abstract | INTRODUCTION: Bioscaffolds derived from animal organs are promising materials for xenotransplantation and regenerative medicine. For effective generation of biological scaffolds from diverse organs, there have been many technical challenges. In this study, we introduced a novel approach to create multiorgan bioscaffolds through systemic decellularization. METHODS AND MATERIALS: To obtain acellular bioscaffolds, the healthy adult rats were systemically perfused with ionic detergent through the carotid artery. Additional liver perfusion was set up to prevent potential obstruction from the influx of the decellularized debris via the portal vein. The perfusion system was controlled to maintain a constant physiological cardiac output of approximately 50 mL/min and was designed to minimize air entrapment. After decellularization, every organ designated for bioscaffold was harvested for evaluation of vascular structure and histology. RESULTS: The perfusion times were different for each organ. In our histological analysis, the decellularized bioscaffolds harvested from most organs including major solid organs (ie, heart, liver, and kidney) as well as the others (such as stomach, intestines, spleen, etc) represented no evidence of residual cellular materials. Furthermore, the well-preserved collagen materials and intact vascular structures were also confirmed. CONCLUSION: The results from this study suggested that this systemic decellularization has the advantages to obtain a variety of bioscaffolds from single donor, and we can even decellularize organs with complex influx vascular structures. This method may also be used to study organ bioengineering for patients who need simultaneous combined organ transplantation. |

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.
