| Outline of Final Research Achievements |
The objectives of this study were to determine (1) culture conditions that enable human fibroblasts to trans-differentiate into chondrocytes and osteocytes, and (2) culture conditions that enable mesenchymal stem cells (MSCs) to maintain proliferation and multilineage differentiation potential in vitro long-term culture. We found a combination of culture supplements that enabled to trans-differentiate human dermal fibroblasts into osteocytes and adipocytes, but not chondrocytes. Furthermore, we found a combination of culture supplements that enabled to maintain proliferation potential of bone marrow-derived MSCs (BM-MSCs) in vitro. The long-term cultured MSCs kept osteogenic, adipogenic, and chondrogenic differentiation capacity and expressed the lineage-specific differentiation markers. These results indicate that the extended culture conditions enabled to maintain proliferation capacity of BM-MSCs while retaining their multipotent differentiation capacity.
