Human ESC-Derived Hair Inducing Cells for Hair Regeneration

Arashi, Swoop, Desmond? What do you guys think about this?

This line of investigation promises to avoid the dp culturing issue.

They directed human embryonic stem cells to generate first NC cells and then hair-inducing DP-like cells in culture.

this is exactly what we need!!!
Dr. Xu described this as the next missing piece as so far he was only able to create ephitelial cells from iPS, but DP cells from iPS was the next step. when those both cell types come together, a new hair follicle is formed. so it turns out that Dr. Xu doesn't have to figure out this step anymore, thus no further crowdfunding required.

i didn't think that this DP cell from iPS creation was coming so fast. that's awesome.

there's one other issue though. iPS cells are currently created by gene editing. although gene editing is very promising and relatively safe to some certain degree, it's still im development, but very fast progressing.
Dr. Xu mentioned that he hopes iPS cells can be created from skin cells by adding different chemical pieces like proteins and so on. this would be easier and more cost effective. (if you remember: unfortunetaly, the story about dipping blood into acid to get stem cells turned out to be untrue).
the other thing is: stem cells are often mixed up, because there are human embryonic stem cells (ethically questionable) and iPS cells which are very similar but not exactly the same. both types are stem cells and have great potential for being transformed into every other cell type like DP cells and so on. but there are a few differences, so it could turn out that iPS cells are not suited for every transformation, or vice versa. it could also be the case that iPS is better for some use cases, compared to embryonic stem cells.

so this is to be seen, and if this last question is answered, then i really don't see why we can't start some fu**ing human trials to create some nice denovo hairs.

First time I've read an article where mice aren't mentioned. Hopefully this goes straight to humans... you know, make it APPLICABLE in the real world.

Yeah, pretty exciting stuff.

Here is something very important:

"Subject-specific iPSC-derived DP-like cells represent a unique unlimited source of syngeneic (i.e. immunologically identical) cells for transplantation therapies to induce hair growth in humans."

That means they are after an autologous (using our own cells) therapy.

Sounds interesting. But I don't get why this hasn't really got a lot of attention before? The article you linked to in the OP is posted on Oct 6, 2014.

This is good news but thing is, when things like these don't get a lot of attention immediately I sort of automatically assume it's nothing special...

it's not really a long time. 3 months only until one of us stumbled across that news.
or are you referring to the usual hairloss cure headlines which should pop up all over the news? =) it's only a matter of time til we see such headlines.
however, i think this is great news. all the talks about retaining lost gene expression during DP culturing is irrelevant in my opinion. i don't think that one of the researchers will ever be able to multiply perfect DP cells with the traditional route, so the route via stem cells, creating fresh fully potent DP cells in unlimited numbers is far more promising.
the only remaining thing, like mentioned, is how to get the stem cells. (gene editing or not?).
as stem cells research is growing exponentially all over the world (as it is the cure to almost everything) i have no doubt that we will see an easy way to achieve this. and even if the way has to be through gene editing, i don't see it as a showstopper. some months ago scientists presented a way how they can exactly control/edit genes very precisely. with such a method you can cure practically every disease.

i would like to here sdsurfin's opinion on it. are you still in contact with Dr. Xu? would be interesting what he has to say about that achievement... and how to proceed with creating iPS cells etc.

i can smell it. the cure gets closer and closer... still some years away, but we're by far not talking about 20 years anymore. if practiced in japan, a cure with stem cells should and could come in the next 5 years, otherwise...

My opinion is that this is another baby step, but we are in the very beginning days of these treatments. Look how long it took replicel to go from a solid idea to where they are now. its been ages and they still don't have anything useable. I have no doubt that new cell therapies are coming, but probably not for most of us on here. Also bimatoprost apparently now is proven to have pretty ****ed up side effects (eye swelling) in most patients, so I'm really not too hopeful for anything in the near future regarding hair loss. Replicel is the only thing with any promise near term, and i have serious doubts about them. The CEO keeps harping on the fact that they will test dosage and repetition, but their new tests do not have a higher dosage, and there is only a second injection. I highly highly doubt that the results will be much better than the first time around. I would still get the treatment if it maintained most hair, but who knows if they will even bring it to market if that is the case.

a baby step? the DP culturing problem is what it's been all about for years. every researcher is trying to retain the quality of DP cells... jahoda, TU berlin, etc.
it's still not possible to multiply them in millions in a traditional way because they lose their gene expression. DP cells creation from stem cells gives you unlimited fresh supply of these cells which alone can trigger the formation of a new hair when implanted into the skin.

did you forget about dr. Xu? why he tried to create those cells from iPS?
i'm wondering how you can call it baby step =)
this is practically the best news since years and will likely lead to the cure on a long-term.

I found out about this experiment on this forum actually and it blew my mind: https://www.youtube.com/watch?v=Qc3fPeNZooA. I wonder if they could use a similar procedure to clone hair follicles. Dr. Xu really seems like a good guy who is open to feedback from hair loss sufferers, maybe some one should bring this experiment to his attention. After all, it was conducted in his state of Pennsylvania.

I can't tell if you are being serious about the eye swelling. You aren't putting it in your eyes for your hair..Secondly, you don't even know Replicel's results from the first time around, so you have no basis to be critical of them.
