| Outline of Final Research Achievements |
To investigate the pathogenesis of moyamoya disease, we induced smooth muscle cells from iPS cells derived from moyamoya disease patients. First, we induced neural crest cells from iPS cells. We found more than 99% of the cells were positive for p75. Next we differentiated these neural crest cells into smooth muscle cells, however, the cells become senescent during differentiation. Although surviving cells were almost positive for α-SMA and SM22, these cells could not be used for next analysis because of cell senescence. Improvement of the protocol is necessary to prevent cell senescence in the future.
