Pluripotent stem cells that can be any cells, such as iPS cells and ES cells are attracting attention in regenerative medicine. On the other hand, research to directly produce target cells by introducing specific reprogramming factors into somatic cells (direct reprogramming) is also been actively conducted. Since iPS cell preparation is not performed, the time required to obtain target cells is short, and it is expected that manufacturing costs will be reduced.

Stealth RNA Vector (SRV) can load many transcription factors and have the outstanding characteristic of being able to erase SRV in a short time as a cell reprogramming vector.
Tokiwa Bio Inc., promotes research on stem cell creation technology using Stealth RNA Vectors (SRV) that can contribute to regenerative medicine worldwide.
