Hanging Drop Hair Cell Culturing

199 Comments

Some important developments in the hair loss world this month.

Hanging Drop Hair Cell Culturing Method

I have covered Dr. Colin Jahoda and his 3D spheroid culturing of dermal papilla cells on this blog before. Mr. Jahoda has been a pioneer in the hair loss research world since the 1980s, but his best years are likely over. Thankfully, the Chinese are continuing from where he left off. A team from Southern Medical University (China) and Dr. Malcolm Xing (Canada) just published an interesting update on their work with 3D spheroids. They have improved somewhat on Dr. Jahoda’s work with a novel hanging-drop method. I am glad that they are continuing this area of crucial research. Note that when I interviewed him, Dr. Xing gave Dr. Jahoda a good deal of credit.

Dormant Phase Crucial for Hair Rejuvenation

Dr. Elaine Fuchs, just published an important article summarizing how stem cells get activated to produce new hair. Forkhead box C1 (FOXC1) is a key transcriptional regulator of hair follicle stem cell activity and bulge maintenance. Also see another summary of the same study. One of the interesting conclusions of the article seems to imply that premature hair loss is also correlated with premature hair greying. Something I have noticed in many people. “Hair follicle stem cells influence the behavior of melanocyte stem cells, which co-inhabit the bulge niche,” explains Fuchs. “Thus, when the numbers of hair follicle stem cells declined with age, so too did the numbers of melanocyte stem cells, resulting in premature greying of whatever hairs were left.”

Other Hair Related News and Developments

— Meiji Seika Pharma (Japan) and Dr. Takashi Tsuji, head of the Laboratory for Organ Regeneration at the Riken Center for Developmental Biology (Japan), have entered into an important partnership. Their goal is “to develop treatments to regrow lost hair.”  Apparently 12 million adult men in Japan suffer from hair loss. The partnership will focus on regenerative medicine rather than on any kind of drug development. Japan’s new laws will also help speed up clinical trials in the regenerative medicine sector.

— Also in Japan, a new article on Shiseido mostly covers things we already know and confirms that they will start trials this year. However, the ending is of interest: “The fee to receive the treatment will be at least 100,000 yen ($887).”  A lot cheaper than I expected.

— Tiny Singapore might have a stagnant and small population, but they still care about hair loss. Their scientists (and others from Stanford) recently published a paper covering the gene Axin2 and autocrine Wnt/β-catenin signaling. Complicated stuff to understand for a non-scientist such as myself.

— Antonio Conte’s hair transplant seems to have turned out pretty good.

And now on to medical items of interest:

I will shorten this section for this month since the hair loss one was so lengthy.

— An interesting recent video discussion between Dr. Aubrey de Grey, Dr. Bil Andrews and Elizabeth (Liz) Parrish. All three of whom I have covered on this blog before.

— Another recent one with just Dr. Bill Andrews.

— How long until we can print human faces in the lab?

Biotechs Target Baldness Market

Biotechs Target Baldness Market

— The latest issue of Nature Biology has an interesting article titled “Biotechs target stagnant baldness market.” My favorite and at the same time least favorite sentence from the article: “It’s been 25 years since Propecia (finasteride), from Merck of Kenilworth, New Jersey, was approved by the US Food and Drug Administration (FDA) in 1992.”

— Thanks to commentator “nosyu” from Japan for posting a link with news from today regarding hair and skin focused Japanese company Adjuvant Cosmetics. It is partnering with Dr. Takashi Tsuji (RIKEN Center for Developmental Biology) and Organ Technologies to conduct joint research on product development for hair and scalp problems.

— Of all the researchers and companies involved in the hair loss world, Replicel has provided us with the most regular updates. This past month has been no exception. Here is a new video with Replicel’s CEO Lee Buckler starting his presentation at 16:11. The presentation was part of the Japan External Trade Organization (JETRO)’s “Investing in Japan” conference in Toronto, Canada that took place on January 29th 2016. The focus of the conference was on Japan’s booming regenerative medicine market. Lee also discusses Replicel’s partner Shiseido.

— Study from Japan suggests that COL17A1 (collagen gene) could be a new target for therapy in preventing hair loss.

— Kerastem clinical trial page was updated at the end of January 2016. Go under the locations section of that page to see if there is a clinic near you where you can volunteer. US only for now it seems.

— Excellent new article summarizing latest hair loss treatment options. One of the co-authors is the famous Dr. Antonella Tosti.

— Polichem (which is working on a topical Finasteride product called P-3074) was purchased by Spain’s Almirall. Also see this new positive study from Italy on P-3074.

— Irish men are increasingly opting for hair transplants like Wayne Rooney. Is a reduction in alcohol consumption next?

And now on to medical items of interest:

— Partisanship in the US hurting 21st Century Cures Act. Thank goodness for Japan, Canada, UK and probably some other countries by now.

— I have discussed Dr. Anthony Atala and the Wake Forest Institute for Regenerative Medicine several times on this blog before. This week, both were widely covered by the media due to the completion of their 3D bioprinter that can make bone, cartilage and muscle (a culmination of 10 years of work it seems). Full journal article here. No mention about hair in there, but a Canadian team’s 3D bioprinter related article from 2014 mentions the eventual feasibility of adding hair follicles to the new skin. Some quotes from Dr. Atala here.

— UK scientists get gene editing go ahead. Now western scientists may become less prone to criticize the Chinese too much like they did last year.

— Oldest heart transplant recipient dies 33 years after getting a new heart. Amazing story. In another article I read, his son said that he died from kidney problems and still had no heart problems.

— If you have older family members that you want to live longer, you might want to find a sketchy doctor who can help remove their senescent worn out cells without government approval.

— A major boost for cryonics.

— A major boost for cancer treatment (using immune cells).
