This study found that rat whisker follicle stem cells can be expanded in culture and transplanted to form functional hair follicles, demonstrating their multipotency and potential for regenerative medicine.

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.

This study demonstrated that multipotent stem cells in adult mice whisker follicles migrate to produce whisker growth, and that this process requires precise control of stem cell trafficking.

In this study, Chinese Herbal Hair Renewal Liquid significantly improved microcirculation disturbance in mice's auricles induced by adrenaline compared with 75% ethanol.

OCT4 helps hair stem cells renew and fight aging, potentially aiding hair regrowth.

In this study, researchers discovered that ROR2, a Wnt receptor, plays a crucial role in regulating hair follicle stem cell self-renewal and maintenance, compensating for the absence of β-catenin.

This study found that the transcription factor Gata6 plays a crucial role in adult mouse hair follicle regeneration by promoting the renewal and preventing DNA damage of rapidly proliferating progenitor cells.

This study found that type II diabetes inhibited hair follicle regeneration and skin cell proliferation in mice, potentially explaining reduced skin renewal and chronic wound formation in diabetes.

This study found that OCT4-overexpressing human hair follicle mesenchymal stem cells show promise for artificial hematopoiesis by enhancing self-renewal through cytoskeletal remodeling and the beta-catenin-dependent adherens junction pathway.

This study found that platelet-derived growth factor signaling is crucial for maintaining the hair follicle dermal stem cell pool and supporting their regenerative capacity.

This study found that Dab2 conditional knockout mice experienced delayed hair follicle cycles and reduced hair follicle stem cell activity, suggesting Dab2's crucial role in regulating stem cell activation and anti-aging process in hair follicles.

This study found that in mice, inactivating beta-catenin in the dermal papilla reduces hair follicle progenitor proliferation and disrupts the hair cycle.

This study found that human hair follicle stem cells formed more colonies and adhered more rapidly, while transit-amplifying cells showed significantly greater mobility.

This study reports that BMP2 expression in goat skin is higher during late telogen and early anagen phases, indicating a potential role in hair follicle regeneration.

This study suggests that label-retaining cells in the hair follicle contribute to follicular renewal, indicating a specific role in the hair cycle by proliferating during the late telogen phase.

This study reviews melatonin's diverse roles in dermatology, highlighting its potential to protect skin from UV damage and oxidative stress, enhance DNA repair, and influence hair follicle cycling, suggesting therapeutic applications in skin care and hair renewal.

Activating cAMP and ATP improves hair growth and strength.

This review discusses how the p53 tumor suppressor gene helps maintain adult tissue homeostasis by promoting the removal of DNA-damaged cells, with implications for treating age-related diseases and p53-deficient cancers; it reports no new results.

This study found that ionizing radiation primarily affects keratinocyte stem cells in the hair follicle, suggesting they play a central role in radiation-induced hair graying, rather than melanocyte stem cells.

This study found that altering cyclin-dependent kinase 4 (CDK4) levels in the bulge region of hair follicles affects the balance of stem cell numbers, potentially influencing hair follicle self-renewal and proliferation.

Human hair follicles can provide stem cells for regenerative medicine.

This review explores the mechanisms of adult stem cell self-renewal, using skin as a model, and reports no new results but raises important unanswered questions in the field.

This study established a new in vitro culture system that supports the growth and dynamic self-organization of hair follicle stem cells and their progeny, promoting a stable population equilibrium.

In this study, the researchers discovered that specific polyamine depletion enhances stemness in hair follicle stem cells through a mechanism independent of mRNA translation.

The researchers noted that cell therapy using dermal papilla cells may be a future strategy for treating androgenetic alopecia.

This review highlights the complexities of hair graying and the limitations of current models to fully replicate hair follicle pigmentary unit function, suggesting that technologies like organoids and bioprinting show promise but require further development for effective hair repigmentation interventions.

This review discusses the process and benefits of Platelet-Rich Plasma therapy for hair restoration, emphasizing its safety and potential for encouraging hair growth, but reports no new clinical results.

This study from PRP Bristol suggests that PRP therapy may stimulate hair growth by revitalizing dormant follicles, noting its rising popularity as a non-surgical option for hair restoration.
