This review evaluates existing research on Keratin 15 to assess its validity as a marker for epidermal stem cells, reporting no new results.

This study found that activin affects both stromal cells and keratinocytes in skin morphogenesis and repair, with dose-dependent effects on keratinocytes demonstrated through transgenic mouse models.

Hair loss in androgenetic alopecia is caused by genetic factors and androgen excess, and can be treated with combined therapies.

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.

This review discusses the potential markers for identifying and studying stem cells in the epidermis and hair follicles, highlighting their role in understanding skin disease pathogenesis and expanding therapeutic options, but reports no new findings.

This review discusses the roles of immune responses and cells in skin health and disease, emphasizing recent insights into their mechanisms and potential therapeutic applications, but presents no new experimental results.

This study found that the vitamin D receptor is crucial for initiating the postnatal hair follicular cycle in mice, preventing alopecia associated with its inactivation.

This study found that Acvr1b signaling is crucial for both hair follicle development and cycling in mice, with the genetic disruption leading to hair loss and a thickened epidermis.

This article reviews fetal scalp hair formation and related disorders but reports no new research results.

This article discusses stem cell-based therapies for wound healing and highlights their potential for tissue repair and regeneration, without presenting new clinical results.

This review describes the molecular interactions between androgens and Wnt/ß-catenin signaling in androgenetic alopecia but reports no new experimental or clinical findings; the authors discuss potential Wnt/ß-catenin-targeted treatments for hair growth.

This report reviews current advances in hair follicle regeneration for tissue-engineered skin grafts and highlights the feasibility and challenges of creating human hair follicles in this setting, suggesting key bioengineering requirements.

This study found that patients with alopecia areata had significant systemic inflammation and vitamin D deficiency, with both conditions more pronounced as disease severity increased.

This study describes the otolaryngologic manifestations and multidisciplinary management strategies for 12 patients with ectodermal dysplasia, emphasizing the importance of early recognition for effective treatment.

This study validated a protocol for inducing surface ectoderm differentiation from human induced pluripotent stem cells and highlighted the role of TGFβ signaling pathways in this process.

Mesotherapy shows promise for cellulite and facial rejuvenation but has mixed results for body sculpting and hair loss, with more research needed for safety and effectiveness.

This review discusses the unique capacity of fetal skin to heal wounds without scarring and notes that while many factors have been identified, the complete mechanism of fetal wound healing remains unclear.
