So apparently there's already a company behind this, called Surrozen (their website).

Link to press release. There are some really impressive people behind this.

Surrozen Launches Into Regenerative Medicine With $33 Million in Series A Financing Led by The Column Group
Founded on key discoveries from Stanford University that enable selective Wnt pathway activation, Surrozen advances novel regenerative medicines with broad applications for human health

SOUTH SAN FRANCISCO, Calif., Feb. 15, 2017 /PRNewswire/ -- Surrozen Inc., a newly formed biopharmaceutical company focused on discovering and developing drugs that promote the repair and regeneration of human tissues, has closed a $33 million Series A financing led by The Column Group, a science-driven venture capital firm based in San Francisco. The funds will be used to implement a broad-based drug discovery platform aimed at unlocking the therapeutic potential of Wnt signaling, which plays a central role in organism development, stem-cell maintenance and tissue regeneration.


"Wnt proteins profoundly impact the formation of tissues and their repair after injury, representing an enormous opportunity for innovative drugs that can address organ degeneration and refractory healing conditions," said Tim Kutzkey, Ph.D., acting CEO of Surrozen and managing partner of The Column Group. "Owing to their poor solubility, Wnt proteins themselves have never been successfully advanced as therapeutics. However, technology developed in the lab of Dr. Chris Garcia, co-founder of Surrozen, has overcome this previously insurmountable hurdle, enabling the generation of active Wnt 'surrogates' with attractive, drug-like properties."

Surrozen's founders include world leaders in the scientific research community and bring complementary expertise in Wnt biology, protein engineering, and stem cells. They are:

  • K. Christopher Garcia, Ph.D.
    Dr. Garcia is a Howard Hughes Medical Institute (HHMI) investigator, professor of Molecular and Cellular Physiology and Structural Biology at the Stanford University School of Medicine, and member of the National Academy of Sciences. He is the principal inventor of Surrozen's surrogate Wnt technology.
  • Roeland Nusse, Ph.D.
    Dr. Nusse is an HHMI Investigator, Virginia and Daniel K. Ludwig Professor of Cancer Research and a professor of Developmental Biology at Stanford University School of Medicine. He also chairs Stanford's Department of Developmental Biology, is director of the Stanford Cancer Stem Cell Research Program, member of the National Academy of Sciences and recipient of the 2017 Breakthrough Prize in Life Sciences. Dr. Nusse co-founded the Wnt field with the discovery of the first Wnt gene (Int1) with Harold Varmus in 1982.
  • Calvin Kuo, M.D., Ph.D.
    Dr. Kuo is the Maureen Lyles D'Ambrogio Professor of Medicine and a professor of Chemical and Systems Biology, leader of the Cancer Biology Program at the Stanford Cancer Center, and vice chair for Basic and Translational Research in the Department of Medicine.
  • Claudia Janda, Ph.D.
    Dr. Janda is a senior scientist at Surrozen and former research scientist and postdoctoral associate in the Garcia Lab at Stanford University. She is co-inventor of Surrozen's foundational technology.
"Wnt pathway activation has been a biochemical puzzle for decades. Our technology opens the door to address fundamental biological and therapeutic questions in tissue repair for the first time," Dr. Garcia said. "I am confident that our team's deep expertise in many complementary areas will drive these important scientific advances into useful drugs."

Surrozen's board of directors includes: Tim Kutzkey, Ph.D., acting chief executive officer of Surrozen and managing partner of The Column Group; David Goeddel, Ph.D., managing partner of The Column Group; Harold Varmus, M.D., co-recipient of the 1989 Nobel Prize in Physiology or Medicine and Lewis Thomas University Professor of Medicine at Weill Cornell Medicine; and Wen-Chen Yeh, M.D., Ph.D., chief scientific officer of Surrozen. In addition to the company's academic founders, Surrozen's scientific advisory board includes Dr. Varmus; Hans Clevers, Ph.D., professor of Molecular Genetics at the Hubrecht Institute in Ubrecht, the Netherlands; and Bart Williams, Ph.D., professor for the Program in Skeletal Disease and Tumor Microenvironment at the Van Andel Research Institute.

"There is perhaps no field within human biology that has more exciting and untapped potential than Wnt signaling," said Chief Scientific Officer Wen-Chen Yeh, M.D., Ph.D., formerly the scientific executive director at Amgen. "Surrozen's foundational technology has the potential to generate a broad pipeline of Wnt pathway agonists that elicit tissue regeneration for a diverse array of conditions with great medical need. Our vision includes gaining a comprehensive understanding of tissue-specific mechanisms guiding the repair process, including the timing of the response and other signals that may be involved."

Between The Column Group and Surrozen, these people are no lightweights and will not be wasting their time on hype and snake oil. But start ups take time and then they will have FDA bullshit to deal with, an automatic 2-3 year jackoff.

I'll say to 3 to 5 years. This is very promising by the looks of things. Garcia is a research prof at HHMI of which Elaine Fuchs was a researcher for a number of years. She also did some work on Wnt pathways and hair biology wrt cancer research. These people are heavyweights for sure.

"Wnt pathway activation has been a biochemical puzzle for decades. Our technology opens the door to address fundamental biological and therapeutic questions in tissue repair for the first time," Dr. Garcia said. "I am confident that our team's deep expertise in many complementary areas will drive these important scientific advances into useful drugs."

Drugs. Some day.

Not really following them, but I'd be surprised if it ever hit the market for hair loss. Results were just too weak.

still in trials.
Anyway even if results were "weak", there was regrowth. And we know that in term of density a low percentage of regrowth can make all difference between visible thinning and a normal looking full head of hairs. On the other side I am obviously always skeptical for drugs to regrowth something on receding hairline or bald crown. But for diffuse pattern, or people in early stages of hairloss this could be something... mby...
Also I have no idea if we can definitely talk of maintenance(!) with such drugs but with my (very) limited knowledge and after I read your post this angle controls miniaturization. right? So...

Personally I believe Samumed would be a spectacular maintanance/ slight regrowth drug. I'd do something to get a lot of hair back them maintain with this.

Drugs have saved more lives than any other medical technology in history. Drugs are the only thing so far that have grown hair during "in the man" clinical trials. Our cellular biology works by molecular signalling, so it is perfectly reasonable to use small molecule drugs to try and correct malfunctioning cells. Our bodies use big molecules, like proteins and sugars as building blocks and smaller molecules for signaling and inhibition. A newer class of drugs called jak-inhibitors are not going away and will be used for a number of immune-related disorders including Alopecia Areata, Alopecias universalis and totalis. And who knows, they may even work for Androgenetic Alopecia. We will know soon enough.

Here’s a study https://www.sciencedaily.com/releases/2017/08/170814134816.htm
Shows that JAK-stat pathway signaling, which produces excess lactate is beneficial for hair regrowth.

"An ideal anagen-inducing therapy would be effective via topical application, but in this study, we delivered Rspo2 via intradermal injection. Transdermal delivery of a 22 kD hydrophilic protein is impractical (Bos and Meinardi, 2000); therefore, alternative delivery methods would have to be devised. Microneedles porate/permeabilize skin in a relatively noninvasive manner, and might be suitable for this purpose (Hultstrom et al., 2014; van der Maaden et al., 2012). Once into the dermis, Rspo2 would likely have to be protected from degradation by proteolytic enzymes, perhaps by liposomal packaging. Whether such a formulation of Rspo2 remains active within the HF remains to be tested."

Don't fly too high with your expecations with studies like this,cause you'll crash badly.
There are thousands,possibly millions mechanisms,pathways,substances involved in normal hair growth,just discovering yet one more of them
is not a big deal.

I'm mostly concerned about the huge role that wnt plays in the human body...
I see a lot of cancer research involving the wnt pathway.

And how many of those "thousands" of pathways and substances discovered were followed up with clinical trials "in the man"? When they submit an IND application, they have to show reasonable expectation for safety and efficacy through basic research done in the lab with animal models. Can anyone point us to clinical trial results for those thousands of old hunches? I think the science is getting better with geneticists like Christiano, Christofk etc discovering new pathways and identifying drugs to target these pathways as a result. And it looks like big pharma is now willing to scoop up the research and try it in people. Mice are nice, but the science isn't complete without people trials. Technological breakthroughs happen when scientists are willing to try new things in different ways and with unpredictable results.

Couldn't agree more.
Research should be emphasized on freshly harvested scalp tissues.In vitro studies and studies on mice are totally useless for male pattern baldness search.

I feel nostalgia for the times when genious scientists like Tesla,Einstein,Max Planck etc. lived on the planet.
