| Abstract | Tissue engineering is one of the major challenges of orthopedics and trauma surgery for bone regeneration. Biomaterials filled with mesenchymal stem cells (MSCs) are considered the most promising approach in bone tissue engineering. Furthermore, our previous study showed that the multi-phase poly [ε-caprolactone]/thermoplastic zein-hydroxyapatite (PCL/TZ-HA) biomaterials improved rabbit (r) MSCs adhesion and osteoblast differentiation, thus demonstrating high potential of this bioengineered scaffold for bone regeneration. In the recent past, CD271 has been applied as a specific selective marker for the enrichment of MSCs from bone marrow (BM-MSCs). In the present study, we aimed at establishing whether CD271-based enrichment could be an efficient method for the selection of rBM-MSCs, displaying higher ability in osteogenic differentiation than non-selected rBM-MSCs in an in vitro system. CD271+ cells were isolated from rabbit bone marrow and were compared with rMSCs in their proliferation rate and osteogenic differentiation capability. Furthermore, rCD271+ cells were tested in their ability to adhere, proliferate and differentiate into osteogenic lineage, while growing on PCL/TZ-HA scaffolds, in comparison to rMSCs. Our result demonstrate that rCD271+ cells were able to adhere, proliferate and differentiate into osteoblasts when cultured on PCL/TZ-HA scaffolds in significantly higher levels as compared to rMSCs. Based on these findings, CD271 marker might serve as an optimal alternative MSCs selection method for the potential preclinical and clinical application of these cells in bone tissue regeneration. |

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.
