This study found that stimulating the olfactory receptor OR2AT4 in human hair follicles with a synthetic sandalwood odorant promotes hair growth ex vivo by decreasing apoptosis and increasing IGF-1 production.

This article reviews the role of stem cells and cytokines in hair growth and discusses existing and potential treatments, but it presents no new clinical data.

In this study, researchers observed that the sebaceous gland niche in mice allows for Wnt-induced hair follicle differentiation, unlike the non-permissive bulge.

This study found that PDCD4 protein expression is reduced in various skin cancers compared to normal skin, suggesting its potential role in preventing or treating certain skin cancers.

In this study, researchers reported that specific immunoreactivity patterns observed in hair follicle stem cell markers suggest different origins for trichilemmoma, basal cell carcinoma, and squamous cell carcinoma in human skin tissues.

This study found that PGF 2α receptors were predominantly present in the inner root sheath of the bulb and stem of human eyelashes during the anagen phase.

This study reports that human hair follicle stem cells express different surface markers than mouse stem cells, facilitating their isolation and potentially aiding in the development of cell-based skin treatments.

This study found that when human hair follicles were grafted onto mice, they progressed through dystrophic stages and returned to normal growth, with stem cells aiding in recovery.

This chapter reviews the anatomy and physiology of hair follicles but reports no new research findings or clinical results.

This study demonstrates that dermal white adipose tissue regulates human hair growth and pigmentation through hepatocyte growth factor secretion, highlighting potential therapeutic targets for hair-related disorders.

In this study, OCT showed strong nuclear binding in certain skin cells, suggesting similar genomic effects to vitamin D with potential therapeutic benefits due to its lower calcaemic effect.

In this study, researchers developed a method to differentiate human iPSCs into cells that can generate all lineages of hair follicles, potentially aiding treatments for hair loss and skin disorders.

This review discusses melanocytes' role in pigmentation, their clinical significance in conditions like vitiligo and hair graying, and highlights current research on hair follicle regeneration without reporting new clinical results.

This study found that intradermal injections of cultured autologous dermal sheath cup cells for androgenetic alopecia showed hair loss stabilization at 24 months without serious adverse effects and a sustained response in some participants.

This study found that dermal papilla and peribulbar dermal sheath cup cells in mice can both induce hair follicle formation, suggesting they may have similar functional roles in hair growth.

This study found that using a 900-MHz GSM mobile phone for 15 or 30 minutes significantly increased single-strand DNA breaks in human hair root cells near the phone.

This article describes protocols for isolating and expanding human epidermal neural crest stem cells and discusses their potential for cell-based therapies in regenerative medicine, but reports no new clinical results.

This study found that co-culturing adipose-derived stem cells with hair follicle-derived melanocytes, combined with narrowband UVB, significantly improved pigmentary response in treating stable, resistant vitiligo compared to non-UVB treatments.

In this study using genetic mouse models, researchers discovered that senescent melanocytes in nevi secrete osteopontin, which activates hair stem cells, enhancing hair growth; this process is mirrored in human hairy nevi, suggesting a potential therapeutic target for regenerative disorders.

This article discusses melanocyte development from neural crest cells and reports no new experimental results; the authors suggest a broader range of functions for melanocytes than previously recognized.

In this study, researchers identified gremilin-2 as a highly specific gene to the dermal sheath cup, suggesting it plays a key role in maintaining its properties.

This review explores recent findings on the roles of melanocyte and melanocyte stem cells in the hair follicle, highlighting their importance for skin health and potential applications in regenerative medicine, but reports no new clinical results.

This study found that human iPSC-derived melanocytes from vitiligo patients successfully integrated into mouse hair follicles and epidermis, demonstrating potential for personalized therapy for depigmentation.

This review discusses the identification and characteristics of melanocyte stem cells, emphasizing their role in hair pigmentation, greying, and skin repigmentation, but reports no new research findings.

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 review discusses the interactions between melanocyte stem cells and their niche in hair regeneration and repair, but reports no new results; recent studies on molecular pathways are highlighted.

This study found that direct interactions between human dermal papilla cells and melanocytes under low oxygen conditions improved cell functions and could be important for hair regeneration efforts.

This paper provides a comprehensive review of melanocytes' roles in skin biology, focusing on their pigmentation and immune functions, and suggests potential research opportunities for preventing and treating skin disorders.

This study found that non-vitiliginous melanocyte stem cells from vitiligo patients were unaffected by the disease and could effectively differentiate into melanin-producing melanocytes, suggesting their potential for use in cellular therapy for vitiligo repigmentation.

This study applied a new RGB trichrome stain to human skin samples, revealing distinct structural staining in normal tissues and potential proteoglycan-rich zones in hair follicles.
