| Outline of Final Research Achievements |
To investigate pathogenesis of polymyositis and dermatomyositis, intrinsic abnormality of the patient muscles has to be studied. From peripheral blood from the patients, we have established human iPS cells that express the MyoD protein inducible with doxycycline. When doxycycline was added in the culture medium, the cells became spindle-like cells and gained characteristics of muscle cells. They produced a wide variety of inflammatory cytokines that are produced reportedly from regenerating muscle cells.
