If they’re making induced pluripotent stem cells, I can’t imagine them using them for any other reason except making hair inductive DP cells. The way I see it, there is no other use for these cells in hair regeneration research apart from doing an SB-like procedure.
That said, I don’t know where the SB “10 year” time frame came from. Is that a definitive statement by the institute itself, or just people on the forums speculating?
Also, I think we’re still missing a lot of facts here. I think Shiseido’s original materials were probably in Japanese and then translated, and the translations were incomplete because as a cosmetics company, they’re mainly interested in PR and marketing, rather than in communicating scientific information.
I also think that they may not have researched this, but rather they jumped on the commercial oppprtunity when Replicel saw what SB had done, and this is how they got the idea.
Once the cat is out of the bag about this stuff, it’s not rocket science to try to replicate it. It may be hard, but it’s not rocket science.
