Research Abstract |
Induced pluripotent stem (iPS) cells were produced by threetransduction systems, retroviral vectors, lentiviral vectors, and adenoviral vectors. The highest production efficiency was obtained when lentiviral vectors were used. This is because lentiviral vectors could show the highest transduction efficiency. When HoxB4 gene, PPARγ gene, and Runx2 gene were transduced with adenoviral vectors with the CA promoter, hematopoietic progenitor cells, adipocytes, and osteoblasts were efficiently induced, respectively, in comparison with conventional differentiation methods. These results demonstrate that adenoviral vectors could be a useful tool for efficient differentiation from iPS cells.
