This study suggests that human dermal fibroblasts can be converted into dermal papilla cell-like cells using microencapsulation, which may facilitate hair follicle regeneration in mice without chemical or genetic reprogramming.

This study observed that alopecia areata can be induced and serially transferred in C3H/HeJ mice using skin grafts, providing a useful model for studying the disease in humans.

This study demonstrated that prevascularized human skin constructs containing engineered hair follicles can successfully induce human hair growth when grafted onto mice by promoting blood supply to the grafted skin.

The study suggests that vaccination with soluble keratin peptides K71 and K31 significantly delayed the onset and progression of autoimmune alopecia areata in mice by inducing T cell anergy.

In this study, topical 5% roxithromycin was effective in restoring hair growth in about half of individuals with androgenetic alopecia without causing adverse effects.

Hair follicle stem cells can become neural cells using different methods, with varying efficiency.

In this study, researchers developed EPO-derived peptides that enhanced hair growth by stimulating dermal papilla cells and increasing IGF-1 expression without triggering systemic erythropoietic effects in tested models, indicating a promising approach for treating hair loss.

p14ARF and p16Ink4a cause hair follicle stem cell aging and dysfunction.

This article reviews the use of laser and light technologies in hair treatments, highlighting their potential and challenges, but provides no new clinical findings.

This study reported that robotic-assisted and specialized tool techniques for FUE hair transplantation have specific indications for different hair types and scalp areas, particularly benefiting patients undergoing multiple transplants.

This review introduces the morphological and molecular principles of hair follicle development but reports no new experimental results, focusing on recent insights and forming a working hypothesis.

In this study, researchers differentiated induced pluripotent stem cells into cells with dermal papilla-like properties, demonstrating their potential role in hair follicle bioengineering and drug testing for hair growth.

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.

This study found that back skin mesenchyme from mouse embryos can induce hair follicle formation even before dermal condensate formation, but R-spondin-1 alone or with a Bmp receptor inhibitor was not sufficient for hair follicle induction.

In this study, neonatal mouse mesenchymal cells showed hair-inducing capabilities, which were lost during in vitro propagation but could be partially restored through specific high-density culture methods.

This commentary discusses the role of the epidermis in hair follicle induction and reports no new research findings.

This study demonstrated that stress inhibited hair growth in mice, likely through substance P-dependent activation of immune cells, highlighting a brain-hair follicle connection.

This study found that downregulation of EGF and KGF signaling is necessary for hair follicle initiation in placodes, revealing a new role for KGF in hair follicle formation in mice.

This study demonstrated that intact adult human dermal papillae can induce hair growth when implanted into mouse hair follicles, highlighting their potential for advancing hair follicle biology and therapeutic approaches.

This study reports that AS101 induced hair growth in mice and suggests potential for treating chemotherapy-induced alopecia in humans, which was observed in case report studies with three adolescents.

This study observed that epidermal growth factor and fibroblast growth factor have distinct roles in sheep skin, with EGF involved in differentiation and FGF in bulb proliferation and fiber growth.

This study reported that exposure to 1,763 MHz radiofrequency radiation stimulated hair growth in vitro by inducing insulin-like growth factor-1 expression in cultured human dermal papilla cells.

In this study, the researchers found that using a core-shell assembly of adipose-derived stem cells and dermal papilla cells reconstructed hair follicle cellular arrangements more effectively than mixed assemblies, enhancing hair formation in vivo.

In this study, Waved-5 mice with reduced EGFR signaling showed nearly normal skin and hair follicle function but experienced a transient reduction in subcutaneous fat.

Laser therapy helped new hair grow in scarred skin for three patients.

This study found that cultured mouse dermal papilla (mDP) cells can induce hair follicle neogenesis in de novo regenerated skin tissues grafted onto mice.

This study found that modulating epithelial and mesenchymal cell interactions in vitro enabled nearly 100% efficient induction of hair follicles, suggesting potential applications for understanding and testing hair growth and graying.

This study observed that incorporating human follicle dermal papilla cells into fibrin microgels increased cell viability and the formation of hair follicle structures in in vitro skin cultures compared to traditional dermal papilla spheroids, suggesting a promising approach for hair follicle regeneration therapies.

This study found that Dkk4-knockout mice exhibited disrupted hair follicle patterning, including a lack of the first wave of hair follicles in the lateral back skin.

This study reported that Dkk4-knockout mice showed disrupted hair follicle patterning, suggesting a WNT-DKK axis may influence regional specificities in hair follicle induction related to androgenetic alopecia.
