| Abstract | Highly porous poly(d,l-lactide-co-glycolide) (PLGA) scaffolds for cartilage tissue engineering were fabricated in this study using the fused deposition manufacturing (FDM) process and were further modified by type II collagen. The average molecular weight of PLGA decreased to about 60% of the original value after the melt-extrusion process. Type II collagen exhibited sponge-like structure and filled the macroporous FDM scaffolds. An increase of the fiber spacing resulted in an increase of the porosity. The storage modulus of FDM scaffolds with a large fiber spacing was comparable to that of the native porcine articular cartilage. Although the FDM hybrid scaffolds were swollen in various extents after 28 days of in vitro culture, the seeded chondrocytes were well distributed in the interior of the scaffolds with a large fiber spacing and neocartilage was formed around the scaffolds. The study also suggested that a low processing temperature may be required to produce PLGA precision scaffolds using FDM. |

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.
