This study found that mice lacking the Sept4/ARTS gene had more hair follicle stem cells and improved wound healing, suggesting apoptosis regulation as a potential target in regenerative medicine.

This study found that cultured human dermal papilla cells formed into three-dimensional spheres have an increased ability to induce hair follicles from mouse epidermal cells compared to two-dimensional cultures.

This study demonstrated that bioengineered hair follicles reconstituted from embryonic skin cells and transplanted into hosts can restore physiological hair functions, suggesting potential applications for treating alopecia.

This paper argues that the cycling hair follicle serves as a valuable model for systems biology research, highlighting its potential for translational medicine.

This study found that overexpressing the BMP inhibitor Noggin in transgenic mice led to a significant loss of nontylotrich hair follicles, suggesting a critical role for BMP signaling in hair follicle morphogenesis and cycling.

In this study, expressing human K16 in the epidermis of K14 null mice prevented early skin blistering but led to age-related anomalies, indicating K16 and K14 have distinct roles despite their sequence similarity.

This study found that hair follicle stem cells can effectively enhance nerve regeneration and restore function in peripheral nerve injuries in mice, suggesting their potential as a source for autologous stem cell therapy.

This review discusses the use of testosterone therapy for low libido in women, noting mixed evidence on breast cancer risk and a lack of long-term safety data.

This study found that cultured dental papilla cells from various mammals can induce hair follicle regeneration and influence tissue formation, with outcomes dependent on donor age, tooth type, and host environment.

This study found that α3β1-integrin is crucial for maintaining normal hair follicle morphology in mice, as its deficiency leads to severe abnormalities despite not affecting interfollicular epidermal differentiation.

Scarring alopecias are complex hair loss disorders that require early treatment to prevent permanent hair loss.

This study introduces the "HoVert" technique, which generates both vertical and horizontal sections from a single biopsy to effectively differentiate lichen planopilaris from discoid lupus erythematosus in alopecia cases.

This review discusses interventions for chemotherapy-induced hair loss and reports no new clinical results; scalp cooling and nutritional support are considered potential strategies but not yet substantiated.

This article explains the structure and multifunctional roles of the human skin, including its protective, regulatory, and sensory functions, but does not report new research findings.

This study demonstrated that tight junction barriers exist in human hair follicles but are less tight in hair follicle keratinocytes than in interfollicular keratinocytes, highlighting claudin-1's key role in follicle barrier function and growth.

In this study, hair follicle stem cells from ND-GFP transgenic mice were observed to be pluripotent, effectively repairing peripheral nerve and spinal cord injuries in mouse models.

This review discusses madarosis, its diverse causes, and suggests follicular unit transplantation as a useful treatment for scarring types, but reports no new clinical results.

This study demonstrates that keratin K2 is crucial for proper keratinocyte structure and function in specific mouse skin areas, and its deficiency leads to cellular aggregates and skin abnormalities.

This review summarizes the anatomy and physiology of the arrector pili muscle and discusses its potential role in hair loss disorders, reporting no new clinical results.

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 review discusses the role of immune cells in mammalian hair cycle control and highlights their potential relevance to human hair cycling disorders, reporting no new clinical findings.

This study identified somatostatin as a potential secretory factor contributing to the immune privilege of human hair follicles.

This study found that in vitro, cultured bulge cells from human hair follicles possess properties of primitive cells, supporting the hypothesis that hair follicle stem cells reside in the bulge area.

This study observed dynamic changes in CD10 and CD34 expression in fetal and adult human hair follicles during embryogenesis and hair cycling.

This case report describes a 68-year-old woman with metastatic breast cancer who experienced significant improvement in visual acuity after stopping tamoxifen, which was associated with bilateral optic neuropathies.

This review discusses recent advances in the genetic understanding of inherited hair and nail disorders and reports no new clinical results.

This review discusses the use of laser and flashlamp technology for unwanted hair removal and reports no new clinical results, highlighting challenges with light-colored hair and treatment safety for darker skin tones.

This study developed a new protocol to efficiently produce skin dermal stem cells from human induced pluripotent stem cells, which may aid in treating various skin disorders.

This study found that selective downregulation of CD200 in the bulge area might contribute to unusual bulge involvement in a subset of alopecia areata cases.

This paper presents two cases of rare intraorbital ophthalmic artery aneurysms associated with arteriovenous malformations and discusses their clinical presentation, pathogenesis, and management, but reports no new clinical outcomes.
