| Abstract | Basement membrane (BM) has been investigated widely and applied in the field of bio-synthesized scaffold design in tissue engineering. However, this respect of investigation has seen scarcely in the field of esophageal tissue engineering. This study reports BM's basic topographic characters and quantification of structural and major proteins involving collagen IV, laminin, entactin, proteoglycans of porcine esophagus. Several methods were adopted to strip epithelium from mucosa tissue. For example, ethylene diamine tetraacetic acid, sonication, dithiothreitol, cold sodium chloride (NaCl), mechanical force of glass coverslip, and cold trypsin and so forth. Assessed experimental results under different conditions, the optimal condition to isolate epithelium from BM was established. After the reaction of cold trypsin at 4°C for 15 h, the BM was isolated from epithelium and exposed integratedly. Hematoxylin and eosin staining and immunohistochemical staining verified the effectiveness of epithelium removal and the integrity of BM. The topographic features of the exposed BM were observed under transmission electron microscopy and scanning electron microscopy. It displayed a rugged surface and 3-D topography consisting of pores and fibers with sub-100 nm range via ImageJ software. The major proteins existing in BM were quantitatively analyzed by enzyme-linked immune sorbent assay. All these results will provide references for the design of synthesized scaffolds and protein modification in esophageal tissue-engineering research. |

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.
