In this study, researchers differentiated human induced pluripotent stem cells into dermal papilla-like cells and observed gene expression dynamics during five stages of dermal differentiation, demonstrating the potential of these cells to interact with epidermal cells in functional assays.

This review critically analyzes recent literature on the use of nanotechnology in alopecia treatment, reporting promising results for improving drug delivery and hair growth, though challenges in maintaining physical stability may limit large-scale commercialization.

This study suggests that a specific region upstream of the TGF-β1 gene may play a key role in androgenetic alopecia by regulating gene expression in a cell-specific manner.

This study found that topical minoxidil modestly extended the anagen phase in mice by activating β-catenin activity in dermal papilla cells.

In this study, dermal papilla cell-derived exosomes accelerated hair follicle growth in mice, suggesting potential for treating hair loss by modulating key signaling pathways.

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

This review indicates that most studies reported positive effects of platelet-rich plasma injections for treating androgenic alopecia, with no major side effects, suggesting it may be a safe alternative to Minoxidil and Finasteride.

This review discusses the potential of endogenic and exogenous exosomes in dermatology and cutaneous aesthetics, highlighting their capacity to repair and rejuvenate skin tissue, but reports no new experimental results.

This review discusses the steroidogenic properties of human skin and suggests that impaired steroidogenesis may be linked to conditions like acne, rosacea, atopic dermatitis, and androgenic alopecia, but reports no new clinical results.

This review discusses potential cell sources and bioengineering strategies for regenerating hair follicles with functional cycling, reporting no new results.

This study suggests that mesenchymal stem cell-induced dermal papilla-like tissues can generate new hair follicles in mice, indicating potential for developing hair cell therapy using stem cells.

This study found that hydroxysafflor yellow A-rich Carthamus tinctorius extract promoted hair growth and gene expression linked to hair proliferation in both cell cultures and mouse models.

This study found that combining minoxidil and retinol additively promoted hair growth in vitro, enhancing Erk- and Akt-dependent pathways and preventing apoptosis in dermal papilla cells and keratinocytes.

This study found that white wax and its extract may promote hair growth in a mouse model of androgenetic alopecia by inhibiting 5α-reductase activity and increasing cell proliferation, with efficacy surpassing finasteride.

This study found that 3-Deoxysappanchalcone may stimulate hair growth in mice by promoting proliferation of hair follicle dermal papilla cells through WNT/β-catenin and STAT signaling modulation.

In this study, quercitrin was reported to promote hair growth and cell viability in cultured human dermal papilla cells by enhancing cellular energy metabolism and growth factor production via MAPK/CREB signaling.

This study found that arctiin, a compound from Arctium lappa, demonstrated protective effects against oxidative stress-induced dysfunction in human hair dermal papilla cells, suggesting potential therapeutic use for alopecia.

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.

This study found that lymphatic vessels promote hair follicle growth in mice and may represent new therapeutic targets for hair loss conditions.

This study found that DHT treatment led to reduced cell growth, increased cell death, cell cycle arrest, ROS production, and senescence in normal human dermal papilla cells, potentially mediated by altered miRNA expression.

This review discusses various approaches to treating alopecia, including drug therapy and hair transplantation, but reports no new research findings; the authors highlight the need for novel techniques like cell culturing.

This study identified distinct gene expression patterns in wool follicle bulbs that may play important roles in wool follicle cycling and regeneration in sheep.

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

This study found that 6-gingerol, a component of ginger, suppresses hair growth rather than promoting it, both in vitro and in vivo, suggesting potential use in hair removal treatments.

This study identified a specific subpopulation of hair follicle stem cells in mice and humans that are essential for long-term hair regeneration, highlighting the potential for regenerative therapy.

In this study, intradermal injection of botulinum toxin was associated with increased hair growth in men with androgenetic alopecia through the suppression of TGF-β1 secretion from dermal papilla cells.

This study found that a newly developed hemi-vascularized sandwich method significantly improved the regeneration and maturity of hair follicles compared to other transplantation approaches in rat models.

This study found that neural stem cell extract enhanced hair growth in mice and cells by stimulating hair follicle niches and activating signaling pathways like TGF-β and BMP.
