제목 The effect of dynamic compression for cartilaginous tissue formation with bone marrow stromal cells
초록 The mechanical stimulation is a very important factor for formation of articular cartilage. The objective of this study is to evaluate the effect of dynamic compression for differentiation of bone marrow stromal cells (BMSCs) within an elastic scaffold and cartilaginous tissue formation. Highly elastic scaffolds were fabricated from poly (L-lactide-co-carprolactone)(5:5) by a gel-pressing method. BMSCs were seeded onto the scaffolds and the continuous compressive deformation was applied to them with 0.1Hz and 5% strain for 10 days in the chondrogenic media. Also, the chondrocytes-seeded constructs were implanted in nude mice subcutaneously to investigate their biocompatibility and cartilage formation. From the results, the periodic application of dynamic compression can encourage bone marrow stromal cells to differentiation to chongenic lineage and to maintain their phenotypes. Consequently, it may improve the quality of cartilaginous tissue formed in vitro and in vivo.
