research Planar cell polarity effector gene Intu regulates cell fate-specific differentiation of keratinocytes through the primary cilia

19 citations , August 2012 in “Cell death and differentiation”

This study found that disrupting the inturned gene in developing mouse epidermis halted hair follicle formation due to impaired keratinocyte differentiation, highlighting primary cilia's role in tissue-specific planar cell polarity signaling.

IL-9 Mediated Human Primary Keratinocytes Invasion Is Dependent on MLC Controlled Contractility and Independent of MMP Activity

research 879 IL-9 mediated human primary keratinocytes invasion is dependent on MLC controlled contractility and independent of MMP activity

April 2018 in “Journal of Investigative Dermatology”

This study found that IL-9 influences the behavior of human primary keratinocytes by promoting motility while reducing invasion potential through a novel mechanism independent of matrix-metalloproteinases.

Generation of Human Hair Follicle Organoids In Vitro and Ex Vivo by Co-Culture of Primary Human Hair Matrix Keratinocytes and Dermal Papilla Fibroblasts

research 773 Generation of human hair follicle organoids in vitro and ex vivo by co-culture of primary human hair matrix keratinocytes and dermal papilla fibroblasts

June 2020 in “Journal of Investigative Dermatology”

This study observed that human primary adult hair matrix keratinocytes may have the potential to generate hair follicle organoids, suggesting possible applications in hair follicle neogenesis and preclinical hair growth agent screening.

research Comprehensive RNA sequencing in primary murine keratinocytes and fibroblasts identifies novel biomarkers and provides potential therapeutic targets for skin-related diseases

17 citations , October 2021 in “Cellular & Molecular Biology Letters”

This study identified novel biomarkers through gene expression differences between keratinocytes and fibroblasts in newborn mice, which may aid in developing therapies for skin conditions.

research Use of primary keratinocyte cultures from plucked human hairs for analysis of gap junctional intercellular communication

3 citations , January 1991 in “Toxicology in Vitro”

This study reports that hair follicle cultures are effective for gap junctional intercellular communication studies and can be used to assess the tumor-promoting activity of certain environmental chemicals.

community Is Vitamin D the cause of my baldness or slow regrowth?

in Is this regrowth? 1 upvotes 10 months ago

The conversation discusses hair loss treatments, including oral finasteride, topical minoxidil, and microneedling, and the potential impact of Vitamin D and folic acid deficiencies on hair regrowth. It suggests that while male pattern baldness is the primary cause, addressing vitamin deficiencies may aid in improving regrowth.

community Bile Acid-Mediated DHT Dysregulation Hypothesis

in Research/Science 13 upvotes 1 year ago

Elevated bile acids can inhibit the enzyme AKR1C2, leading to increased DHT levels, which may accelerate hair loss in those predisposed to androgenetic alopecia. Treatments mentioned include topical minoxidil and finasteride.

community Topical Finasteride Doesn't Directly Reduce 5ar Enzyme on Scalp

in Finasteride/Dutasteride 72 upvotes 3 years ago

Topical Finasteride doesn't directly reduce 5ar enzyme on scalp and has the same mechanism as oral, needing to go through the liver. Users debate the accuracy of this information and discuss various studies and experiences.

community Primary Care Provider told me to not be concerned and just take biotin.

in Finasteride/Dutasteride 2 upvotes 1 year ago

A 19-year-old was advised by their primary care provider to take biotin for hair loss instead of minoxidil or finasteride due to potential side effects and age concerns. The user is considering seeking a second opinion from a dermatologist.

community GT20029 China Phase II Trial For AGA Reached Primary Endpoint

133 upvotes 2 years ago

The GT20029 tincture, a topical androgen receptor degrader, showed significant hair growth and good safety in a China Phase II trial for male androgenetic alopecia (AGA), with the 1% dose twice weekly identified as optimal. The company plans to initiate Phase III trials in China and Phase II in the U.S., and the treatment also shows promise for acne.
