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.

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.

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 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 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 review summarizes recent advances in understanding the molecular mechanisms of hair follicle formation and discusses potential future clinical applications for treating hair loss and skin tumors, but it reports no new clinical results.

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 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 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.

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.

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.

Results are not reported in this abstract, which outlines research investigating why diabetic mice experience suppressed hair follicle stem cell activation, potentially contributing to chronic diabetic wounds.

Activating cAMP and ATP improves hair growth and strength.

This study found that human hair follicle-derived mesenchymal stem cells maintained their proliferation and differentiation potential when cultured with acidic fibroblast growth factor, basic fibroblast growth factor, or epidermal growth factor.

This study reviews the potential of rosemary for hair loss treatment, highlighting its beneficial bioactive compounds that may support healthier scalps and promote hair growth, though inconsistencies in formulations and lack of long-term safety data suggest more research is needed.

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

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 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 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 found that while calcium can substitute for the Vitamin D receptor in maintaining epidermal keratinocyte differentiation, it cannot compensate for hair follicle dysfunction caused by the absence of the receptor.

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.

This study found that GDNF promotes hair formation and wound repair in mice by enhancing the function of bulge stem cells.
