I didn't say he was money hungry. Scientific research is driven by hype and grants. People/governments/organizations are more likely to want to fund his other research initiatives while they are generating hype from a pre-clinical program.Forgive me for entering the speculation / amateur psychologist mode, but I suspect that Tsuji might not be money driven. People who excel in their profession are usually possess genuine passion, because Dollar / Yen signs in your eyes only get you that far. Add the honor driven culture of Japan, which I do not know enough about unfortunately, and I can imagine they would release the cure even if it would break even financially. Would your life feel complete if it would revolve around this research, while never being able to deliver the big promises? That is why I don't believe in scenario's where they need money and are totally unreasonable towards potential partners, thus resulting in no offers being made.
Also, they don't just look for one partner, but are open to a wide array of cooperations. You can explain that positively by suggesting that they have big plans and need a lot of assistance for those. Given that they haven't shown a PoC of it working in humans, I don't think they need partners for a mass rollout. I think they just, ehm, need a lot of assistance.
Again, hopefully, in time people will be able to laugh about this post given how wrong it was.
If we want to talk about money though, how about the fact that he put this entire thing on hold while he launched 3 cosmetic hairloss topicals that don't outperform minoxidil?
