This study found that Dermal Fibroblast Progenitors have repressed chromatin profiles which hinder their ability to reform skin in allograft assays despite their differentiation potential.

This study identifies a bipotent stem cell in adult hair follicles that self-renews and contributes to dermal sheath and papilla cell populations, potentially aiding hair regrowth after injury, disease, or aging.

This study found that minoxidil stimulates hair follicle growth by promoting dermal papilla cell survival and activating ERK and Akt pathways, which leads to increased proliferation and reduced cell death.

This study found that treatment with mesenchymal stem cell extracellular vesicles enhanced hair growth in mice and stimulated dermal papilla cell activity and growth factor production in vitro.

This study suggests that the postnatal loss of hair follicle formation in wounds may be due to elevated Wnt/β-catenin activation in the dermis, affecting fibroblast function in mice.

This study found that Sonic Hedgehog secreted by hair follicle transit-amplifying cells is essential for dermal adipogenesis and hair follicle growth by acting on adipocyte precursors.

This study proposes the miR-22-5p-LEF1 axis as a novel pathway that may regulate hair follicle stem cell proliferation.

This study found that testosterone and 5α-dihydrotestosterone induced apoptosis in dermal papilla cells from nonbalding scalp regions, suggesting a high androgen stimulus can trigger cell death related to androgenetic alopecia.

In this study, mice exposed to prolonged space conditions demonstrated skin atrophy, altered hair follicle cycles, and significant changes in the gene expression associated with skin muscle health.

This study found that using 3D dermal papilla spheroid models enhances extracellular matrix production and hair follicle marker expression, providing insights into hair follicle biology and potential for drug screening.

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.

This study suggests that new cells are incorporated into the dermal papilla during the early anagen phase of the hair cycle, which may influence hair growth consistency and follicle size changes.

This study found that combining herbal extracts with PRP increased human dermal papilla cell proliferation via ERK and Akt protein regulation, suggesting its potential for developing hair growth therapies.

This review discusses recent advances in the role of dermal papilla cells and adipocyte lineage cells in hair regeneration, but it reports no new clinical results.

This article explains the preparation methods and applications for various vesicle and particle systems used in transdermal drug delivery, highlighting their effectiveness and potential for further development in this field.

This study found that four microRNAs, which were significantly upregulated in balding hair follicle papilla cells, could play a role in the development of male pattern baldness.

Finasteride potentially treats hair loss by reducing DHT production.

This study found that dermal papilla cells cultured in vitro can promote hair follicle regeneration and maintain hair growth, with stronger ET-1 and SCF expression enhancing this regenerative ability.

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 review discusses the use of derma rollers for cosmetic purposes and their potential in transdermal drug delivery by summarizing evidence on their design, efficacy, safety, and concerns from preclinical and clinical reports.

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 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 injecting a combination of human cultured dermal papilla and epithelial cells induced hair growth in a mouse model.

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.

This study found that chi-miR-30b-5p was more expressed in the telogen phase than in the anagen phase and inhibited dermal papilla cell proliferation by targeting CaMKIIδ.

This study suggests that the long noncoding RNA H19 helps dermal papilla cells maintain their hair follicle-inducing ability by activating the Wnt signaling pathway, potentially offering a therapeutic target for androgenetic alopecia.

This study identified proteins that are differentially expressed in balding versus non-balding dermal papilla cells, potentially aiding the understanding and treatment of androgenetic alopecia.

This study found that transplanted cultured epithelium from adult rat sole keratinocytes can respond to growth signals from dermal papillae and form follicular structures, especially with dermis support.
