Glossary Dermal Papilla Cells

specialized cells at hair follicle base crucial for hair growth

Dermal Papilla Cells (DPCs) are specialized cells located at the base of hair follicles. They play a crucial role in hair growth and regeneration by interacting with surrounding cells to regulate the hair growth cycle. These cells are essential for the formation of new hair follicles and are a key focus in research on hair loss treatments and regenerative medicine.

research Sox2-positive dermal papilla cells specify hair follicle type in mammalian epidermis

338 citations , July 2009 in “Development”

This study demonstrates that Sox2-positive dermal papilla cells specify particular hair follicle types by showing heterogeneity in gene expression and pathway activation in these cells.

Microenvironmental Reprogramming by Three-Dimensional Culture Enables Dermal Papilla Cells to Induce De Novo Human Hair-Follicle Growth

research Microenvironmental reprogramming by three-dimensional culture enables dermal papilla cells to induce de novo human hair-follicle growth

256 citations , October 2013 in “Proceedings of the National Academy of Sciences of the United States of America”

This study found that altering cell culture conditions to form three-dimensional papilla spheroids can restore the ability of human dermal papilla cells to induce hair growth in adult skin.

research Balding hair follicle dermal papilla cells contain higher levels of androgen receptors than those from non-balding scalp

227 citations , January 1998 in “Journal of Endocrinology”

This study found that dermal papilla cells from balding scalp hair follicles have significantly higher levels of androgen receptors than those from non-balding follicles, supporting their in vivo androgen response.

research Dermal papilla cell number specifies hair size, shape and cycling and its reduction causes follicular decline

211 citations , April 2013 in “Development”

In this study, researchers found that the number of dermal papilla cells in hair follicles determines hair size and shape in mice, suggesting potential avenues for addressing hair loss.

Cultured Peribulbar Dermal Sheath Cells Can Induce Hair Follicle Development and Contribute to the Dermal Sheath and Dermal Papilla

research Cultured Peribulbar Dermal Sheath Cells Can Induce Hair Follicle Development and Contribute to the Dermal Sheath and Dermal Papilla

208 citations , December 2003 in “Journal of Investigative Dermatology”

This study found that dermal papilla and peribulbar dermal sheath cup cells in mice can both induce hair follicle formation, suggesting they may have similar functional roles in hair growth.

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.

learn SCUBE3

a signaling molecule from dermal papilla cells being actively researched

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.

learn Platelet-Rich Plasma

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.

learn Centella

Not eating well lately and your hair’s falling? A centella-based supplement might give your roots the boost they’re begging for. There is no published human trial showing that an oral Centella asiatica (gotu kola) supplement stops hair shedding caused by poor nutrition; the evidence is laboratory work on dermal papilla cells, inflammation and collagen, and community reports mention centella only in topical products.
