Shiseido’s Dermal Sheath Cup Cell Hair Multiplication Treatment Has Arrived

Today might be among the five most important days in the hair loss world since I first started writing this blog in 2013. Shiseido’s decade-plus-long much awaited dermal sheath cup (DSC) cell hair multiplication (cell culturing and implantation) procedure is finally here for patients starting July 1, 2024. Albeit only in Japan, where they have favorable regulations for faster in-clinic use when it comes to regenerative medicine and stem cell based technologies.

Shiseido (Japan) completed small-scale Phase 3 equivalent trials for this hair multiplication technology in 2023. The results were positive but modest, with no major side effects. I hope the results will improve as they use this autologous DSC cell transplantation process in more patients and gain experience.

For now, you should only expect existing scalp hair thickening and perhaps minimal hair regrowth if you are lucky. Thicker hair in and of itself could lead to a slowdown in further damage from the ravages of dihydrotestosterone (DHT).

You can read today’s full announcement here (h/t “Theo” for the super find). The technology is described as having been developed by Tokyo Medical University Hospital, Kyorin University Hospital, and Shiseido. Interestingly, they leave out any mention of Replicel (Canada), with which Shiseido has had past legal issues after a technology sharing agreement went wrong.

S-DSC® Hair Regenerative Medicine

Shiseido has also created a new website related to S-DSC hair regenerative medicine, where the “S” stands for Shiseido. The about S-DSC page is very interesting. S-DSC® treatment promotes hair growth by supplementing the thinning areas of your scalp with your own cultured DSC cells.

They only make claims that existing hair will get thicker and more voluminous, while scalp inflammation will be reduced. Perhaps they also want to temper expectations, even if some people may get good regrowth? Interestingly, women might get better results then men.

The key person who led the development of this technology is Professor Emeritus (Department of Dermatology, Tokyo Medical University) Dr. Ryoji Tsuboi. I feel like a genius for using his image as my main one on my global hair loss research page from the get go. I originally picked Dr. Tsuboi over Dr. Takashi Tsuji just due to a more interesting image of the former at a white board.

Hair Regenerative Outpatient Treatment Begins in Japan on July 1, 2024

Associate Professor Shiro Niyama of the Department of Dermatology at Toho University Ohashi Hospital will start offering this “hair regenerative treatment for thinning hair” using cultured autologous hair bulb root sheath cell products (S-DSC®) from July 1st 2024. Patients will be required to get a referral, and also be responsible for their own costs due to the elective nature of the procedure. Note that this treatment is available for both men and women.

In the procedure itself:

  1. First, healthy scalp tissue of about 5 mm diameter is taken from a non-balding area such as the back of the head.
  2. From this, DSC cells are isolated.
  3. S-DSC is produced after about 6 weeks of culture and quality inspection (a total of 7 vials of S-DSC can be produced).
  4. Once production is completed, patients will return to the hospital and the cultured DSC cells will be injected with a special syringe.

Also check out the November 2023 study from the same team that is titled: “High migratory activity of dermal sheath cup cells associated with the clinical efficacy of autologous cell-based therapy for pattern hair loss.” The conclusion was that ITGA6-positive DSC cells, with superior migratory activity, may promote cell migration into nearby hair follicles.

Aderans and Intercytex: Hair Multiplication Failures

In a first for this blog, I am updating a post from ten years ago! Perhaps I should change the title and remove the word “failure”? I wonder how many of the original 15 commentators are still visiting this site?

Update: March 9, 2024

Stemson Therapeutics and Aderans Announce Licensing Deal

Earlier today, Stemson Therapeutics (US) and Aderans (Japan), the parent company of Bosley® and HAIRCLUB®, announced a partnership agreement (licensing deal).

This arrangement secures Stemson the exclusive global rights to research, develop and commercialize hair regeneration therapeutic products based on Aderans’ proprietary hair regeneration cell therapy technology. Note that Aderans and and Intercytex represented the only two major hopes for a hair loss cure throughout the 1990s and early 2000s. And then companies both folded and made me originally write this post a decade ago.

Stemson today likely represents the number one hope for a hair loss cure, although there are a number of other contenders in China, Japan, South Korea and the US. At least when it comes to much improved hair loss treatments

Getting back to Stemson, the company is developing a proprietary cell therapy for reversing hair loss that is based on induced pluripotent stem cells (iPSC). Per the press release, it now:

“Gains a complementary technology through this agreement. Stemson will resume Aderans’ Phase 2 clinical stage cell therapy hair regeneration program, integrate the technology into its existing hair loss cell therapy development pipeline, and provide multiple products for patients experiencing hair loss.”

What a great development. Aderans is back from the dead. It also seems like a backup plan for Stemson in case its main iPSC technology does not pan out. Moreover, Stemson seems to want to resume Phase 2 trials for Aderan’s hair regeneration technology. And Japan has more favorable regenerative medicine sector regulations when it comes to trials and in-clinic use.

Quote from Stemson CEO Geoff Hamilton:

“The synergies between the Aderans technology and Stemson’s in-house technology will help us accelerate timelines across our programs.”

Quote from Aderans CEO Yoshihiro Tsumura:

“We look forward to working with the Stemson team to enable their development efforts and to support the commercialization through our global network of clinics serving hair loss patients.”

Quote from the evergreen Ken Washenik (Chief Medical Officer of Bosley Medical and former CEO of Aderans Research Institute):

“Our pioneering work at the Aderans Research Institute to develop the first ever cell therapy solution for hair loss showed tremendous promise in clinical trials to treat early stage Androgenetic Alopecia in men and women. We believe Stemson, with their advanced expertise in hair follicle cell and tissue engineering, is ideally positioned to successfully complete development and commercialization of this exciting hair regeneration solution.”

Aderans and Intercytex: Hair Multiplication Failure

All the great news this year related to hair loss research, trials and potential cures has made people very optimistic. However, a lot of hair loss sufferers are becoming excessively passionate about a select few companies (especially Histogen and Replicel) or about the results from a select few clinical trials.

I therefore decided to write this post as a warning from past experiences of putting too much faith into any one or two entities. Something as simple as lack of sufficient funding despite successful stage 2 clinical trials can cause a company to stop pursuing highly promising products.

In the early-to-late 2000s, two companies named Aderans (Japan) and Intercytex (UK) caused tremendous excitement in all the online hair loss forums. Both were involved in groundbreaking research related to hair cloning and hair multiplication.

Moreover, Aderans’ research was led by the renowned Dr. Ken Washenik through the Aderans Research Institute. He made numerous presentations about their technology at various conferences. Below are two of those:

However, in 2013, Aderans decided to liquidate its research institute. Spencer Kobren had a segment about this on his usually weekly Bald Truth show. Also starring legendary hair loss sufferer and caller “Joe from Staten Island”.

Intercytex abandoned its dermal papilla cell culturing work in 2010 due to financial difficulties, despite positive results from phase 1 trials. According to the company’s website, in 2010 the Intercytex name and ICX-RHY were purchased by private investors and relaunched as Intercytex Ltd. ICX-RHY is a skin repair product.

As of 2014, Aderans’ research is focused on wigs and hair replacement. They purchased US-based hair restoration market leading companies Hair Club in 2013 and Bosley in 2001. Intercytex as a company is no longer in existence.
