| Abstract | In this study we hypothesized that as a simulation of endochondral bone formation, bone marrow stromal cell (BMSC) provide a sequential chondro-osteogenic differentiation potential. A chondrogenic priming of BMSC leads to a spontaneous three-dimensional cell formation. BMSC were chondrogenically differentiated prior to an osteogenic stimulation. Duration of cell culture was 28 days, whereas in group A BMSC were chondrogenically differentiated for 1 day, followed by an osteogenic differentiation for 27 days. In group B BMSC were chondrogenically differentiated for 14 days prior to an osteogenic differentiation of 14 days and group C BMSC were differentiated chondrogenically for 28 days serving as a chondrogenic control group. Chondrogenic priming induced a spontaneous three-dimensional cell formation. To survey the stability of the osteogenic phenotype in the absence of an osteogenic stimulus, investigations were performed in vivo in a specially adapted chorioallantoic membrane model of fertilized White Leghorn eggs. Histology and real time polymerase chain reaction revealed a higher amount of osteogenic extracellular matrix synthesis and significant higher expressions of osteogenic marker genes in group B after 14 days of chondrogenic and 14 days of osteogenic stimulation. Matrix calcification in vivo in the absence of an osteogenic stimulus could be demonstrated. The results of the present study support the theory of a sequential differentiation potential of BMSC. A chondrogenic priming of BMSC stimulated into the osteogenic lineage result in a stable osteogenic phenotype in a scaffold-free, three-dimensional tissue engineering application. |

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.
