This review discusses the cell biological characteristics of the outer root sheath of normal human hair follicles and highlights some similarities and differences with trichilemmal tumors, but reports no new results.

Cyclosporin doesn't stop hair loss.

This review discusses the formation and maintenance of hair follicles through dynamic cellular changes and signaling pathways, presenting a comprehensive overview but providing no new experimental findings.

This study found that the absence of Hes1 in hair follicles delays secondary hair germ activation and shortens the anagen phase, impacting HFSC self-renewal and long-term hair regeneration.

This chapter reviews dermatological drugs and cosmetics, identifying common allergens and preservatives linked to contact dermatitis without reporting new clinical results.

This review introduces the morphological and molecular principles of hair follicle development but reports no new experimental results, focusing on recent insights and forming a working hypothesis.

TGF-β signaling is essential for hair follicle regeneration during wound healing.

This article reviews the stages and regulation of the hair cycle, highlighting molecular regulators involved, but it does not present new research findings.

This review discusses the mechanisms of wound-induced hair neogenesis and its similarities with embryonic hair follicle development, but reports no new clinical results.

In this study, demodicoses were found to be relatively common among immunocompetent patients, with a notable overlap with papulopustular rosacea.

This review indicates that estrogen loss during menopause significantly impacts skin health, while estrogen treatment may increase skin collagen, thickness, and elasticity, though effects on other skin characteristics are inconsistent.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

In this study, four children with recurrent atypical teratoid rhabdoid tumors experienced disease stabilization or regression after treatment with alisertib, suggesting its potential role in future trials for this condition.

This review discusses recent advancements in understanding hair follicles, their disorders, and potential therapeutic opportunities, but it reports no new clinical findings.

In this study, murine follicular cell aggregates developed into hair-like structures in culture, which upon implantation into mice skin matured into complete hair follicles, suggesting potential for treating hair loss.

This study found that epidermal melanocytes can regenerate hair follicles, whereas non-cutaneous or dermal melanocytes cannot, suggesting two distinct melanocyte lineages with potential implications for melanocyte-related diseases.

This review discusses the cutaneous side effects associated with vemurafenib and ipilimumab in metastatic melanoma treatment and emphasizes the importance of dermatologists in managing these skin eruptions; it reports no new clinical results.

This study found that Punica granatum ethanolic leaf extract may alleviate skin fibrosis in rats by modulating inflammation-related pathways and reducing dermal alterations.

This conference proceeding abstract provides no new research results, focusing only on event details from the British Association of Dermatology's Forty-Sixth Annual Meeting held in Oxford in 1966.

This review summarizes the major events and regulators of the hair cycle in mammals but reports no new experimental results; it emphasizes the complex regulation of stem cell activation and differentiation during hair growth.

TGF-β signaling is essential for new hair growth after wounds.

This review explores the mechanism and potential applications of wound-induced hair follicle neogenesis but reports no new clinical results, highlighting the need for further research in hair regeneration therapies.

This study suggests that hepatocyte growth factor (HGF) may play a role in hair follicle neogenesis and that an HGF mimetic could enhance skin substitute development.

This article reviews the role of epithelial-mesenchymal interactions in hair follicle development and discusses the challenges of understanding the signals that regulate this complex process; it reports no new results.

This study characterizes gene expression patterns in embryonic hair follicle progenitors and their niche, identifying signaling pathways like axon guidance that may drive cellular rearrangements for hair follicle formation.

This article reviews the morphogenesis and cycling of hair follicles and the complex signaling pathways involved, without reporting new experimental results.

This article explores how adult mammals can regenerate hair follicles after wounding and suggests that manipulating cell signals during healing might enhance this process, but provides no new experimental results.

In this study, researchers observed that HIF1α is expressed in germ cells throughout fetal and neonatal development, suggesting it may regulate telomerase activity and maintain the undifferentiated state of stem/progenitor cells.
