To regenerate the complex tissue such as bone-cartilage construct using tissue engineering approach, controllable differentiation of bone marrow stromal cells (BMSCs) into chondrogenic and osteogenic lineages is crucially important. This study proposes to test a minimum common osteochondrocytic differentiation medium (MCDM) formulated by including common soluble supplements (dexamethasone and ascorbic acid) used to induce chondrogenic and osteogenic differentiation. The MCDM coupled with supplemented growth factors was tested for its ability to differentiate BMSCs into osteogenic and chondrogenic lineages in both 2-dimensional (2D) and 3-dimensional (3D) culture systems. When transforming growth factor β3 (TGF-β3) was added to MCDM, BMSCs differentiated to chondrocyte-like cells evidenced by the expression of glycosaminoglycans and type II collagen, whereas osteogenic differentiation was induced by supplementing osteogenic protein-1 (OP-1), resulting in detectable expression of osteopontin and osteocalcin. These chondrogenic and osteogenic differentiation markers were significantly enhanced in the 3D cultures compared to the 2D monolayer cultures. The results achieved in this study lay a foundation for future development of osteochondral graft, which could be engineered from bilayered scaffold with spatially loaded growth factors to control BMSC differentiation.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
