For now only: Replicel and Histogen!
They were just injected into mice.. the cells were from human origin. So, this is definitely different than, "just another mouse study".

I concur.

Jahoda solved the trichogenicity problem partially. You and I debated this before.
The Chinese are saying they have taken up where Jahoda left off and improved on the degree of trichogenicity.
Also, have you taken a look at Kerastem? Do you recall that you said the problem with adipose derived stem cells is that they don't stay in the injected area. Well, you were right...that is the problem.
Kerastem may solve this problem and it does appear that it is producing some solid results. Plus the FDA has authorized a phase 2 study already.

Do you mind explaining the difference between gene expression and Trichogenicity?

Sure. Trichogenicity just means the ability to induce a hair follicle. That's what Jahoda already achieved. Yet after expansion of the cells, genetic information was lost in the process. The cells still were able to induce a hair follice, but the resulting hair wasnt cosmetically viable: it was thin and without colour and I think it didnt even reach the surface.

Thanks. Do you mind me asking what you do? You seem pretty knowledgable on this stuff, and I'm trying to learn.

So 8 passages just means they managed to make 256 dp cells out of just 1 dp cell and all those cells still were able to induce a hair follicle.
I guessed that was what a passage was, but what I was ultimately wondering was how far away this is from becoming a viable treatment, ie. how many passages is needed?
And is that really true, you only need 1 dp cell to grow a whole follicle? Did they grow 256 follicles? Or 1 follicle using all 256 cells? Or something in between?

Some posters at various sites are saying the new Chinese technique is NOT producing better hairs than Jahoda did but that is not my interpretation of the Chinese results. Some are saying that the hairs are still without color and aren't the right size and other such
problems. But my understanding is that the Chinese are saying that they are producing hairs that are good quality. Am I missing something? I haven't seen the whole study.

i'm not sure, but i think this achievement probably means nothing, again.
but we will never know anyway, as they never dare injecting it into a human scalp.
they will be playing around with mice for another decade.
also, if it's true, according to roger_that (you know him well), even sanford&burnham messed up because they misinterpreted their results. the resulting grown hairs were mouse hairs, although they injected the human cells into the nude mice. this is a huge dissapointment as it seemed as the real deal a few months ago. if sanford burnham really messed this thing up, then shame on them. they received millions of funds, probably also because of the latest breakthrough, but if the achievement wasn't real at all, then it's pointless anyway.
i learned that nothing will come from all those researchers worldwide who tinker around with hanging drops and other crap. probably we would already have found a cure if they would finally set up a small human trial. but it will not happen in the next 10 years.
kerastem is also a scam. it's time to face the truth. aape, prp, and now kerastem which is just a slightly advanced form of the adipose thing, this all is useless. it might be beneficial to some degree, but the results are negligible. we simply can't revive the dormant hairs with fat cells and growth factors.
replicel is the only thing left. if it turns out to be ineffective as well, then NOTHING will help us in the next 10 years. mark my words.

That's what I think too. All this stuff is interesting but not relevant for us anyway. Highly experimental, not working yet and years and years of testing needed. Not going to happen within the next 10 years. And who knows, it might even take way longer than that.
