research Paracrine TGF-β Signaling Counterbalances BMP-Mediated Repression in Hair Follicle Stem Cell Activation

321 citations , January 2012 in “Cell stem cell”

This study identified TGF-β2 as a crucial signal in hair follicle stem cell regeneration, highlighting its role in counteracting BMP signaling to promote tissue regeneration.

research Androgen‐inducible TGF‐β1 from balding dermal papilla cells inhibits epithelial cell growth: a clue to understanding paradoxical effects of androgen on human hair growth

190 citations , October 2002 in “The FASEB journal”

In this study, androgen did not affect keratinocyte growth in coculture with androgenetic alopecia-derived dermal papilla cells, but did significantly suppress keratinocyte growth when androgen receptor was overexpressed in the papilla cells.

research Human bone marrow mesenchymal stem cell-derived exosomes stimulate cutaneous wound healing mediates through TGF-β/Smad signaling pathway

139 citations , May 2020 in “Stem Cell Research & Therapy”

In this study, human bone marrow mesenchymal stem cell-derived exosomes significantly accelerated cutaneous wound healing in rats by modulating the TGF-β/Smad signaling pathway.

research Conditional epidermal expression of TGFβ1 blocks neonatal lethality but causes a reversible hyperplasia and alopecia

103 citations , July 2001 in “Proceedings of the National Academy of Sciences”

This study found that conditional expression of TGFβ1 in mice affects epidermal and hair follicle growth, with chronic expression causing severe alopecia and a negative feedback loop involving Smad7.

research Dermal Blimp1 Acts Downstream of Epidermal TGFβ and Wnt/β-Catenin to Regulate Hair Follicle Formation and Growth

85 citations , June 2017 in “Journal of Investigative Dermatology”

This study found that Blimp1 plays a key role in promoting hair follicle morphogenesis and growth by mediating inductive signaling pathways in dermal papilla cells.

community A new study by Deng and colleagues set out to explore differences between balding and non balding scalps...

39 upvotes 4 years ago

Balding scalps have more androgen receptors, leading to increased TGF-beta, which causes blood vessel loss and hair follicle miniaturization. Blocking androgen signaling and TGF-beta may help prevent hair loss.

community Possible topical option for preventing BDNF-related hair loss

6 upvotes 2 years ago

The conversation discusses hair loss linked to BDNF-increasing nootropics like Semax and Lions Mane. Suggested topical treatments include capsaicin, beta-glucan, and ginseng to counteract TGF-B activation.

community My Theory Of Androgenic Alopecia

16 upvotes 10 months ago

Hair loss is linked to cellular physiology and the IGF-1 to TGF-B1 ratio, not just androgen sensitivity. The theory lacks evidence, while finasteride and minoxidil are effective treatments.

community Article on the newest baldness cure(prolactin drug)

7 upvotes 5 days ago

A new hair regrowth treatment involving a prolactin drug is discussed, with some users questioning its role in hair loss compared to DHT. The conversation also mentions other factors like Wnt/b-catenin and TGFb in hair loss.

community Update about Hair Follicle Glucose Metabolism: New Clinical Data Collection with Ex-President Of American Board Of Hair Restoration Surgery.

39 upvotes 2 years ago

David Barreto shared that a London-based research group is conducting a 12-month trial for a new nutraceutical treatment for pattern hair loss, designed with Dr. Carlos Puig. The trial aims to provide robust data, with results expected in 1-2 years, potentially representing a significant advancement since finasteride’s introduction in 1997.

Protein that blocks activin, a growth-regulating signal

learn SCUBE3

What do clinical trials say about the safety and effectiveness of SCUBE3 for hair regrowth? No clinical trial of SCUBE3 for hair regrowth has been registered on ClinicalTrials.gov or published, so there is no human safety or effectiveness data. The evidence is limited to one 2022 laboratory and mouse study reporting that SCUBE3 activates hair follicle stem cells through TGF-beta signalling.
How does SCUBE3 work on hair follicles compared to treatments like minoxidil or finasteride? Laboratory research in mice reports that SCUBE3, a protein released by dermal papilla cells, signals dormant follicles to grow through the TGF-β pathway downstream of Hedgehog; minoxidil and finasteride instead work on blood flow to the follicle and on DHT, and unlike SCUBE3 they have decades of human trial data behind them. SCUBE3 has not been tested in human clinical trials and is not available as a medicine.
