[iPS cells for the generation of cartilage and for regenerative medicine and disease modeling of cartilage diseases].

The development of induced pluripotent stem cells(iPSCs)has enabled the acquisition of patient-specific chondrocytes by converting somatic cells, such as dermal fibroblasts or blood cells, from patients to iPSCs and then differentiating them toward chondrocytes. We can further generate cartilage tissue from iPSC-derived chondrocytes. Studies on iPSC-derived chondrocytes/cartilage for the regeneration of articular cartilage injury are ongoing. These studies will in the future use autologous iPSCs and allogenic iPSCs from an iPSC stock prepared from donor cells. Drug discovery research for related diseases such as skeletal dysplasia is also being conducted.
