| Outline of Final Research Achievements |
We considered which ECM component (i.e., Collagen typeⅠ, gelatin, fibronectin, collagen typeⅣ) combined with each inducer (bone morphogenetic protein (BMP)-2, -4, -7) was the most suitable to support the proliferation of human induced pluripotent stem (iPS) cell lines and their differentiation into odontoblast-like cells. The results showed us that 10% gelatin combined with BMP-4 was most suitable.
On the other hand, we tried to generate iPS cells with three episomal plasmid vectors (including four factors) for reprogramming human gingival fibroblasts. They were transfected with electroporation and have been confirmed by the expression of reprogramming genes by qPCR.
