This study identified three genes with significantly higher expression in androgen-sensitive beard dermal papilla cells compared to androgen-insensitive scalp cells, suggesting potential novel signaling pathways in hair follicles.

This research reviews the roles of dermal papilla signaling in hair follicle development and suggests new genetic tools could advance bioengineering therapies for alopecia, but it reports no new results.

This review discusses recent advances in understanding the molecular landscape of the dermal papilla, particularly focusing on Blimp1's role in hair follicle development and potential therapeutic targets for hair regeneration, but presents no new clinical results.

This study suggests that policosanol may prevent androgenetic alopecia in mice by regulating hormone levels and suppressing premature hair follicle entry into the regression phase.

Using a combination of specific cell cycle regulators is better for safely keeping hair root cells alive indefinitely compared to cancer-related methods.

In this study, researchers established three specific cell lines from Cashmere goat hair follicles and found that cytokeratin 13 might be a novel biomarker for identifying dermal sheath cells.

This study found that dermal papilla cell-conditioned medium can protect against UV-induced skin aging in a mouse model by modulating ferroptosis pathways, highlighting its potential for treating oxidative stress-related skin conditions.

This study found that age-related changes in scalp dermal fibroblasts, including increased MMP-1 and reduced ECM components, may significantly affect the hair follicle environment and contribute to hair aging.

Protease Nexin-1 is found in human hair growth cells and is affected by male hormones.

This study reports that in aged mice, hair follicle dermal stem cells exhibit diminished self-renewal and preferential differentiation into dermal sheath cells, contributing to age-related hair loss.

In this study, researchers found that crude extracts from Avicennia marina and its component avicequinone C inhibit mechanisms contributing to androgenic alopecia in vitro, including 5α-reductase activity and DHT-AR interactions, potentially promoting hair growth and delaying the catagen phase in human dermal papilla cells.

This study found that using gallate-containing formulations like EGCG or tannic acid increased the solubility and controlled release of finasteride in microspheres, enhancing its dermal penetration in pig skin by 10 to 50 times compared to a control.

This study found that low-level laser therapy may improve hair growth in patients with androgenetic alopecia, either as a standalone treatment or combined with minoxidil or finasteride, without reported adverse reactions.

The researchers reported that hair follicle germinative epidermal cells can form complex structures when associating with papilla cells in culture, unlike other types of epidermal cells.

This study found that a novel 3D in vitro culture condition improved stemness markers and proliferation potential in human dermal stem/progenitor cells compared to traditional 2D methods.

This study found that dermal EZH2 plays a crucial role in controlling fibroblast differentiation by regulating Wnt/β-catenin and retinoic acid signaling during skin development.
