research Exosomes derived from dermal papilla cells mediate hair follicle stem cells proliferation through the Wnt3a/β-catenin signaling pathway

January 2022 in “Figshare”

In this study, researchers found that dermal papilla cell exosomes can enhance hair follicle stem cell proliferation and reduce apoptosis through the Wnt3a/β-catenin signaling pathway, offering insights for potential hair problem treatments.

Overexpression of Nanog in Amniotic Fluid-Derived Mesenchymal Stem Cells Accelerates Dermal Papilla Cell Activity and Promotes Hair Follicle Regeneration

research Overexpression of Nanog in amniotic fluid–derived mesenchymal stem cells accelerates dermal papilla cell activity and promotes hair follicle regeneration

14 citations , July 2019 in “Experimental and Molecular Medicine”

This study suggests that the secretome from amniotic fluid-derived mesenchymal stem cells overexpressing Nanog could stimulate hair growth and increase follicle density, potentially aiding in alopecia treatment.

research Platelet-derived growth factor signaling modulates adult hair follicle dermal stem cell maintenance and self-renewal

37 citations , April 2017 in “npj Regenerative Medicine”

This study found that platelet-derived growth factor signaling is crucial for maintaining the hair follicle dermal stem cell pool and supporting their regenerative capacity.

research Exosomes Derived from Dermal Papilla Cells Mediate Hair Follicle Stem Cell Proliferation through the Wnt3a/β-Catenin Signaling Pathway

2 citations , January 2022 in “Oxidative Medicine and Cellular Longevity”

This study suggests that exosomes from dermal papilla cells can regulate hair follicle stem cell proliferation via the Wnt3a/β-catenin signaling pathway, potentially informing treatment for human hair problems.

research Hair follicle dermal stem cells and skin‐derived precursor cells: Exciting tools for endogenous and exogenous therapies

30 citations , April 2017 in “Experimental Dermatology”

This review explores the role of hair follicle dermal stem cells in skin regeneration and restorative therapies, but it reports no new experimental results.

community Hair Multiplication Projects in China - Promising clinical trial results on Mice

34 upvotes 1 year ago

A breakthrough in hair follicle cultivation using induced pluripotent stem cells (iPSCs) has been achieved, producing large hair follicles suitable for transplantation. Clinical trials for this hair multiplication technology are planned in partnership with Yinguan Biotechnology.

community A Theory on Why Microneedling Works

175 upvotes 6 years ago

Microneedling may enhance hair regrowth by transferring stem cells to dormant follicles, improving the effects of minoxidil. Users discuss using microneedling with needle lengths around 1.5mm to stimulate hair growth.

community Anyone Try Microneedling with Exosomes/AAPE?

2 upvotes 4 years ago

User asks where to purchase exosomes/AAPE for microneedling hair loss treatment. Links to research on hair regeneration therapy, stem cell therapy, exosome therapy, and dermal exosomes provided.

community Everything you ever wanted to know about Pelage Pharma's PP405: how it works and what to expect

126 upvotes 3 months ago

PP405 may encourage earlier hair growth and slightly increase visible hair count but does not reverse hair follicle miniaturization in male pattern baldness. It does not address damage to the dermal papilla or broken Wnt signaling.

community We already know how to permanently fix hair loss. The science is done. The only thing missing is the funding to run one experiment.

in Technology 613 upvotes 4 months ago

A permanent hair loss solution could involve reprogramming hair follicles to resist DHT using mRNA and siRNA. However, high costs, safety concerns, and the pharmaceutical industry's preference for ongoing treatments over one-time cures are major obstacles, with finasteride and minoxidil remaining standard treatments.

What is Platelet-Derived Growth Factor Beta Polypeptide, and how does it help stimulate new hair growth? PDGF-BB is a growth factor that signals to dermal papilla cells and promotes blood-vessel formation; mouse studies report it can push follicles into the growth phase, and human evidence comes only indirectly from PRP trials. No PDGF product is approved for hair restoration and there is no published human trial of PDGF-BB on its own.
