Yes but that's not what they'll be doing for a phase 1 safety test & proof of human concept test, otherwise that's exactly what I just said. The phase 1 test is going to be patches of hair on bald scalp, similar to the Stemson or Tsuji mice pictures. Would pictures of 10 follicles in one spot after 90 days encourage you to drop 750k if you knew nothing else about the science?
Tsuji told you this, or someone else at RIKEN? I would have thought they'd do at least one full scalp procedure in phase I to show off. They should all be full scalp procedures. Preclinical would be just a one cm spot, then the clinical trials should be exactly what they are going to do in the clinic, otherwise it's not a true test.

Make no sense to goo ful head of hair on first try.
So many thing could go wrong . They should do at first 1 square cm then see that there no weird reaction and the hair come out in normal direction and there is no ingrown hair which would be horrible .. they need to do baby step when its come to human . Until they prefect it .

Before doing a phase I they do a smaller safety test in humans. This will be where they test 1cm².

"Phase 0 involves exploratory, first-in-human (FIH) trials that are run according to FDA guidelines. Also called human microdose studies, they have single sub-therapeutic doses given to 10 to 15 subjects and yield pharmacokinetic data or help with imaging specific targets without introducing pharmacological effects. Pharmaceutical companies perform Phase 0 studies to decide which of their drug candidates has the best pharmacokinetic parameters in humans."

So stemson will do it as well? After the pig trails?

Sometimes in phase 1 they literally give people a single dose of a medication. For BAY & Kintor's KX they dosed the back/abdomen of patients with a single doage, no where near the scalp or hair for either one. I would be very surprised if phase 1 was anything more then a patch of hair.

Maybe, maybe not. Nobody here is going to be getting it regardless

There are various types of human hair shafts, which play a role in protection from the outside world, perception, and social communication. The basic structure of the hair follicles that create each hair shaft is the same. The fate of this hair type is determined by the fetal body plan and is remembered by the dermal papilla. Planting hair follicles elsewhere does not change the fate of the hair species.

In other words, moving an occipital hair to the top of the scalp doesn't change the fact that it's resistant to miniaturization.

So they pretty much know by their own research that hair restoration with multiplication will clear Androgenetic Alopecia out!? That's satisfying and terrifying at the same time... Cool!

Wait what do you mean clear Androgenetic Alopeicia out, I'm confused lol

There plenty of evidence that even the the hairs from the donor zone thinned in a matter of 2-3 years after the transplant . A time period that way faster to thinned rather then if it would never been extract from donor zone.

That's probably because they are being taken from areas where the person was already prone to miniaturization (ie the NW5-6 zone) and then get blasted by scalp DHT plus shock damage on move. Even with FUT, I see strip scars in the NW6 zone on the sides all the time.

Hang around the transplant world for long enough and you hear plenty of those reports. Transplanted hairs thinning and donor area thinning. It's not a consistent thing but it definitely happens. Severe baldness takes no prisoners. The "safe zone" is not 100% safe, it's just being hurt less severely.

Some guys even report their transplanted hairs thinning faster than the rest of the donor hair it came from. It's not unheard-of.

The guys who got early plug grafts (like 4mm chunks) used to report a "donuting" problem where the center of the grafts would bald out compared to the perimeter. I don't think that has ever been explained very well. Just catch-all explanations like "reduced circulation due to scarring". IMO the phenomenon seemed too specific for that to cover it.

Nope im taking about the safe one the real donor zone.

Then they have dupa/retrograde or another type of hair loss that extends to the new follicles like a scarring alopecia that was never treated. This isn't a one size fits all.
