This study reported that baicalin activates the Wnt/β-catenin signaling pathway in mouse hair follicles, suggesting its potential as a topical treatment for hair loss.

The study found that up-regulating β-catenin signaling in CD 133-positive dermal papilla cells enhanced their ability to promote hair follicle regeneration both in vitro and in vivo.

This study found that colchicine treatment significantly reduced hair fiber elongation in cultured hair follicles and altered protein expression and activity in dermal papilla cells, suggesting a role for the ubiquitin-proteasome system in its effects.

This study explored the effects of a new narrow-band red LED light on hair growth in mice, showing potential benefits compared to existing laser therapies.

This study found that injecting autologous dermal sheath cup cells significantly increased hair density and diameter in male and female pattern hair loss compared to a placebo for up to 9 months.

This study suggests that icariin promotes hair follicle growth in mice by enhancing IGF-1 expression in dermal papilla cells.

This study found that adding Wnt-10b to the culture medium of dermal papilla cells maintained their ability to induce hair follicles over 100 days in vitro.

Androgen effects on hair follicles vary by skin area.

This study reports that versican expression plays a crucial role in maintaining the anagen phase and hair inductive properties, as shown in a transgenic mouse model and hair growth assays.

This case study reported a diagnosis of dermatophytic pseudomycetoma in a Persian cat with dermal nodules, highlighting potential heritable predisposition and suggesting systemic antifungal therapy for fair prognosis.

This practical guide introduces methods to study human dermal white adipose tissue but does not report new clinical results, emphasizing available techniques and staining protocols.

This study found that fibroblast behavior switching between proliferation and ECM deposition is vital for dermal architecture, where cell migration is primarily important for tissue repair during wound healing.

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 identified a gene expression signature in mouse embryonic dermal fibroblasts that depends on Wnt/β-catenin activity, potentially influencing dermal fibroblast identity and function.

This study successfully established an immortalized human dermal papilla cell line that maintains characteristics of original cells without malignant transformation, potentially benefiting hair research.

This study found that hypoxia increases the proliferation of dermal papilla cells and highlighted the important role of lactate dehydrogenase in this process.

This study suggests that androgens enhance growth factor production in dermal fibroblasts, which in turn may alter keratinocyte differentiation and contribute to acne lesion formation.

This study found that the water extract of Cinnamomum osmophloeum Kanehira leaves enhanced hair growth in vitro and in a mouse model, suggesting potential use for treating hair loss.

This study found that angiogenin is expressed in human dermal papilla cells, where it might stimulate hair growth by promoting cell proliferation and local skin angiogenesis.

This study suggests that miRNAs, particularly miR-195-5p, may regulate the loss of hair follicle inductivity in cultured dermal papilla cells by suppressing the Wnt/β-catenin pathway.

This study found that proteins secreted by early-passage dermal papilla cells, including SDF1, MMP3, biglycan, and LTBP1, may play significant roles in hair follicle regeneration.

This study found that using layer-by-layer encapsulation techniques on dermal papilla cells can support their function and may help treat hair loss when used in conjunction with freshly isolated epidermal cells.

This study found that dihydrotestosterone (DHT) may shorten the hair growth cycle through mechanisms like cell-cycle arrest and β-catenin downregulation in rat hair follicle cells.

TGF-β1 increases androgen receptor activity in hair loss, but Hic-5/ARA55 can counter this effect.

This study observed that mast cells and increased collagen and elastic fibers in the scalp may contribute to male pattern hair loss, but additional research is needed for further understanding.

This study observed that testosterone inhibits hair follicle epithelial cell proliferation in adult stumptailed macaques only when dermal papilla cells from bald scalps are present, with antiandrogen RU 58841 reversing this effect.

This review discusses using cultured dermal papilla cells to investigate hair follicle biology, emphasizing their potential to inform treatments, but reports no new clinical results.

This study found that dermal papillae in alopecia areata, including clinically normal follicles, exhibited ultrastructural abnormalities that suggest an early pathological role in the disease's development.

This study found that dermal papilla cells from balding follicles exhibit distinct growth characteristics compared to non-balding cells, suggesting their potential as a model for understanding androgenetic alopecia.

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.
