Yeah pretty much. We are likely not going to have access to Tsuji 2020, despite that being everyone's pipedream. Tsuji of course in making great progress, and still has a few problems to solve. But even if the tech were ready by tomorrow, which it is not, scaling up takes time. Their labs need to be able to have high throughout to culture everyone's samples. The optimised protocol needs to be established. This is clearly more involved than an fue, if you want to control hair density, growth direction, etc. for a nice result.
Imho, some people here misunderstand the 2020 deadline. Its likely that they aim to start human trials by then. Now I know that Japan's laws allow early release, but again scaling up and having high throughput facilities is a sizable engineering challenge (which is still much easier than a research challenge in which the answers are unknown and need to be discovered). Commercialization necessitates high throughput. But that's also not Tsuji's job though. He is the lead researcher is all.
The good news though is that the degree of balding of the patient appears to have no bearing on the treatment effectiveness, and of course the treatment is poised to be a full cure. Good stuff.
