RIKEN Announcement: Succeeded in Developing Tech for HF Regenerative Medicine: Study to be Published Feb 10

It all depends if Stemson can utilise MHRA's ILAP pathway, and its been looking like they're going to attempt to go down that route for at least one of the products they try to commercialise.

While Tsuji may have a confirmed pathway to clinic, he hasn't got funding still (that we know) so its hard to believe that they're closer. A realistic expectation is confirmation of a partnership this year for Tsuji and co IMO.

They're probably going to use the MHRA ILAP pathway for their initial product while trialing the secondary one through the regular channels, that's how the pitch deck read to me anyways. I say they're on the market 1-3 years prior to Tsuji, without counting the commercial availability of later stage trials in Japan.

This is assuming the process actually works, of course.

 

[trialAcc]

Hopefully the UK gov will give them an innovation passport, even if they don't meet the criteria exactly it seems the gov is willing to bend a little if you've got substantial investment from the UK. Still a chance they could get turned down though.

I highly doubt they get turned down, but we'll see. This is the exact type of treatment a country like the UK wants to welcome in with open arms post brexit. They want to establish themselves as a new innovation hub after getting free of the EU restrictions.

True. I hope they do. We are waiting on Tsuji to get funding and Stemson to take advantage of ILAP. I just don't think it's going to take Tsuji much longer to get funding. I think middle of the year and then start trials first quarter next year. They said within a year of getting funding, which is probably closer to six months. That would put them at mid 2023 for market launch, which is going to be hard for Stemson to beat even if they do take advantage of ILAP in the UK.

Yep Organ Tech, forgot the name, that's why I put a ? behind it and Tsuji didn't start yesterday, it took him 10 years to get to this point and we gotta see how much time will pass until this will be ready for a broad spectrum for people. So 10-15 years ain't the fastest ever, maybe for such a research it's a short period, but not fast.

Kyocera is far from bankrupt, and they are still working with RIKEN. It is Organ tech that was supposed to conduct the trials but went under. Who exactly is faster than Tsuji? Tsuji has been ready for human clinical trials since 2020, He will probably still beat Stemson to human trials, and almost certainly beat them to market.

 

[Mighty]

the drug Belzutifan has received approval according to ilap. They only continued the studies up to 2a. If Stemson starts the study early next year and starts the second study in the same year, they could make it by 2023. By 2024 at the latest

"latest"... Do you wanna bet?

I see some hype around here. I hope that, whatever it is, this time the company succeeds.

 

[Joxy]

Stem Cells/iPSCs, CRISPR-Cas9, 3D/4D bio printing open new tremendous possibilities in science, but they are all in very early stage of research.

I will never understand why companies who can grown 5 hairs gets 15-20 million dollars investments, but on other hand Dr.Tsuji is begging people to donate money, so he can continue with research...

 

[Joxy]

Yeah, not really sure what this means "If this clinical study reveals its safety and efficacy, it can be implemented in society as a paid clinical study."

However, they said they'd start their trials within a year of receiving the necessary funding, not just within a year, so who knows how that'll go.

It means that they must firstly proof and verify their technology through legit clinical trials.

I guess they have other techniques than mice to see how their technology will translate on humans

I dont think so, they're going to do a full human study but it just wont be a full procedure, instead they will probably transplant full density into patches of 1cm/sq. If successful & safe, they will open it in a clinical setting and allow willing customers to come get the full procedure done with the condition that they are part of the phase 2/3 trials.

"Change the fate of the "top of the head" to the "occipital region" ...?​

In order to put hair follicle regeneration into practical use as regenerative medicine, it is necessary to develop a technology that stably increases the two types of stem cells that make up the origin of hair follicles in vitro. Over the course of more than 7 years, we have developed a technology to stably increase two types of cells in vitro.

In particular, androgenetic alopecia is known to be caused by dermal papilla cells, which are "mesenchyonic stem cells", among the two types of stem cells. Considering this, it is possible to change the fate of the transplanted hair follicles on the crown to the "occipital type" by using the dermal papilla cells of the "occipital region" that do not cause alopecia."

I think that this approach is really interesting and actually effective for Androgenetic Alopecia, meanwhile stemson tries to achieve their mesenchymal cells/DP cells from neural crest cells, and those again from hESCs, so not the certain occipital cells, just randomized cells. can't gather anything from Stemson's sience in terms of achieving occipital-like follicles.

Nevertheless it is hard to cultivate DP cells, there will be amplification problems, so I wonder how Dr. Takashi Tsuji does it!? When trying to multiply or cultivate DP cells, they lose their hair inducing function.

In conclusion: Tsuji's apporach seems more valuable and complex than Stemson's. And in the end more effective for Androgenetic Alopecia.

 

[Pls_NW-1]

DP cell cultivation isn't a problem.

Also, in terms of scientific value.. stemsons is arguably more valuable as it only requires blood to be drawn.

Also there's never been conclusive evidence of hair follicles being resistant to balding in the occipital, the literature actually points more to it being the tissue in the occipital, more so than the follicle. There's also been studies showing that taking dp-cells from occipital and placing them in balding areas doesn't change the trascriptinome of balding follicles.

Either would be a massive step forward, no point trying to compare them though.

I thank you very much for your reply, yadonkey!

May I ask why's it then that hair transplants last for a long time - life time!?

Edit;
Oh, I see you were referring to something RepliCel does, placing DP cells into the balding scalp. Sure that it does not help much.

This in vitro study revealed that androgen-insensitive follicles still respond differently to androgens than androgen-sensitive follicles after being isolated from surrounding tissue, proving that androgen sensitivity is programmed within the follicle itself.

Androgens trigger different growth responses in genetically identical human hair follicles in organ culture that reflect their epigenetic diversity in life​

Hair follicles were isolated by carefully following each follicle from the hair bulb toward the epidermis, removing adjacent epidermis, dermis, and subcutaneous fat (Fig. 1D) (9), and collected into sterile Petri dishes

variations in androgen response are presumably a result of location‐specific epigenetic differences in gene expression, likely established within developing hair follicles by site‐specific variations in exposure to paracrine regulatory molecules during embryogenesis.

If anyone really believes that androgen sensitivity is in the skin and not the follicle then they shouldn't worry about Tsuji or Stemson because hair multiplication won't work. They won't be transplanting occipital scalp tissue along with the hair germs.

 

[pegasus2]

I just glanced at that study, but it doesn't prove that epigenetic differences in balding scalp during embryogenesis don't lead to transcriptome changes later in life. Then again, maybe this is why Tsuji can't get any money. They know his hair germs won't grow in balding scalp.

DNA methylation patterns established in youth, in combination with other epigenetic marks, were able to accurately predict changes in transcript trajectories with aging. These findings are consistent with the developmental origins of disease hypothesis and indicate that epigenetic variability in early life may explain differences in aging trajectories and age-related disease.

Early-life DNA methylation profiles are indicative of age-related transcriptome changes - Epigenetics & Chromatin

"Hair Loss Will be Cured Within Ten Years"​

Probably not lol :')

"Hair Loss Will be Cured Within Ten Years"​

Probably not lol :')

Ya almost definately not. Honestly it's amazing how much conjecture we can get from so little information though. Does the entire biotech sector seem as botched as companies focused on hairloss or is it just hairloss research? It seems so strange to me that after 20 years of continuous research these labs run out of resources or just something that didnt happen ever before ends up happening right when the going gets good. Is that strange or normal occurrence?

 

[Pls_NW-1]

I really ask myself where the money is really going, is it really going into research or just the pockets of the scientists.

It definitely goes into research.
But the questionmark lays there, where the research is going to... lol.

Ultimately, Where goes the research!?

The last couple of years it went literally into NOTHING.

 

[pegasus2]

"Hair Loss Will be Cured Within Ten Years"​

Of course it will. I wouldn't bet my life on this working, but I would bet my house. There's little chance of it not working in humans

 

[Pls_NW-1]

I mean, you guys assume that when putting Tsuji's hair into a balding scalp/area, it won't grow, because it starts acting as a balding follicle due to the tissue being placed in.

We do know that when you plant a scalp hair follicle onto your arm, it will start to bald at some point, and we do know that hair transplant's last for a long time. Consider the fact that we are talking here about an endless supply. The science is there, if it won't work on humans,... that'll be very weird. However, we are indeed far away from such interventions.

He's not saying that, he's saying the opposite.

Sorry I wasn't referring to someone certainly. Just in general sorry for some miss-info or negative vibe, didn't meant that.

I thought that the bet was about when the cure will become available for most ppl...

Will a treatment like Tsuji's be released in the next years? Probably. Will it be available for the "common" ppl? Probably not. We will have to wait for the rich and the bald men that believe that their soul resides in their hair to be cured first.
