The Enhancement of Dermal Papilla Cell Aggregation by Extracellular Matrix Proteins Through Effects on Cell–Substratum Adhesivity and Cell Motility

research The enhancement of dermal papilla cell aggregation by extracellular matrix proteins through effects on cell–substratum adhesivity and cell motility

44 citations , June 2009 in “Biomaterials”

In this study, fibronectin coating on a low-adhesive substratum increased cell aggregation, growth, and motility, enhancing the formation of hair follicle dermal papilla spheroids.

research The effect of ovine secreted soluble factors on human dermal papilla cell aggregation

3 citations , January 2016 in “International Journal of Trichology”

This study found that soluble factors secreted by ovine dermal papilla cells enhance the aggregative behavior of human dermal papilla cells, potentially improving their follicle-inductive properties for hair replacement therapy.

research Knockout of p16INK4a promotes aggregative growth of dermal papilla cells

2 citations , October 2017 in “Revista Da Associacao Medica Brasileira”

The study found that silencing the gene p16INK4a in dermal papilla cells promotes their growth and aggregative behavior, suggesting a potential therapeutic target for androgenetic alopecia.

research Evaluating the Characteristics of Human Hair Follicle Dermal Papilla Cells in Aggregation Culture Procedure

April 2026 in “Biomedical and Biotechnology Research Journal (BBRJ)”

In this study, researchers observed that using microtube-based forced aggregation, human hair follicle dermal papilla cells formed stable, compact spheroids at higher cell densities, showing enhanced expression of specific markers compared to 2D culture.

Molecular Functional Analyses Revealed Essential Roles of HSP90 and Lamin A/C in Growth, Migration, and Self-Aggregation of Dermal Papilla Cells

research Molecular functional analyses revealed essential roles of HSP90 and lamin A/C in growth, migration, and self-aggregation of dermal papilla cells

10 citations , May 2018 in “Cell death discovery”

This study found that the interaction between heat shock protein 90 and lamin A/C is crucial for the growth, migration, and self-aggregation of dermal papilla cells, suggesting a potential role in alopecia areata mechanisms.

community HairClone (UK) finally begins offering its Dermal Papilla Cell Hair Multiplication procedure to humans. In Guatemala.

149 upvotes 6 months ago

HairClone is offering a Dermal Papilla Cell Hair Multiplication procedure in Guatemala, raising questions about its effectiveness and regulatory reasons for the location. Users express skepticism and curiosity about the treatment's success and potential costs.

community New Peer-Reviewed Publication Further Validates RepliCel's Use of Dermal Sheath Cup Cells to Treat Pattern Baldness - Paper entitled "Hair Follicle Dermal Stem Cells Regenerate the Dermal Sheath, Repopulate the Dermal Papilla, and Modulate Hair Type" published journal Developmental Cell

13 upvotes 11 years ago

A new treatment using dermal sheath cup cells may regrow hair and could require repeat treatments every 8 years. Users discuss ongoing trials and plan to use finasteride and minoxidil until the treatment is available.

community [Nov 2019] The peptide AC 2 isolated from Bacillus-treated Trapa japonica fruit extract rescues DHT (dihydrotestosterone)-treated human dermal papilla cells and mediates mTORC1 signaling for autophagy and apoptosis suppression

23 upvotes 6 years ago

A peptide from Japanese water chestnut fruit may help with hair loss by suppressing DHT's effect on hair follicle cell death, potentially serving as a finasteride alternative. The treatment's effectiveness and safety in humans remain uncertain.

community New Hair Loss Cure: AMP-303 Is Back. It’s what PP405 should have been.

7 upvotes 5 months ago

AMP-303 and AMP-601 are new hair loss treatments targeting dermal papilla cells, with AMP-303 showing early efficacy in transitioning vellus hairs to terminal hairs after one injection. Further clinical trials are planned, and these treatments are seen as promising due to their biologic approach and less frequent application compared to daily treatments.

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

126 upvotes 2 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.
