| Outline of Final Research Achievements |
We established cleidocranial dysplasia (CCD)-derived iPS cells (CCD-iPSCs) and also established Revertant-iPSCs in which RUNX2 mutation of CCD-iPSCs was corrected by CRISPR / Cas method. These iPSCs had pluripotency. In osteogenic induction analysis, expression of osteoblast differentiation markers such as ALP, OSX, OCN, and DLX5 was increased only in Revertant-iPSCs. In the rat calvarial bone defects transplantation experiment, the bone closure delay was observed in the CCD transplant group, and both bone volume and bone mineral content were lower than Revertant transplant group. From the above results, it was confirmed that the established CCD-iPSCs exhibited bone mineralization disorder accompanying osteoblast differentiation abnormality.
