This study found that mice lacking the 1αOHase enzyme, which is responsible for producing a key vitamin D metabolite, showed impaired epidermal differentiation and delayed recovery of skin barrier function after disruption.

This review discusses how Western diet may contribute to acne vulgaris through insulin signaling and metabolomic changes, promoting a dietary approach for management, but reports no new experimental results.

This review discusses the distinct roles and surprising developmental flexibility of multiple somatic stem cell types in tissue maintenance and repair, reporting no new results but highlighting emerging questions about their regulation and origins.

This study found that matriptase, a membrane serine protease, is crucial for maintaining multiple types of epithelial tissues in mice, with its absence leading to severe organ dysfunction and increased permeability.

This review synthesizes recent research on exosomes, highlighting their role as key modulators in regenerative outcomes and suggesting they may offer advantages over stem cell-based therapies in process and regulation.

This research found that feather pattern formation in birds is regulated by a mechanochemical system involving fibroblast growth factor and bone morphogenetic protein signaling, which is altered in the flightless emu and ostrich.

In this study, human dermal fibroblasts were identified as natural host cells that support productive Merkel cell polyomavirus infection, and the MEK antagonist trametinib was introduced as an effective inhibitor to control the virus.

This review explores how adipose-derived stem cells contribute to skin homeostasis and highlights recent advances in their clinical applications in dermatology, but it reports no new clinical results.

This review explores the development and cosmeceutical applications of microneedles for skin treatment, without reporting new clinical results, emphasizing safety and public perception as key factors for commercialization.

This review explores recent findings on regulatory T cells, focusing on their unique functions in non-lymphoid tissues and new mechanisms of action, but presents no original clinical results.

This study found that Na CMC hydrogel loaded with PEG-coated silver nanoparticles demonstrated superior antibacterial and wound-healing efficacy compared to commercial silver sulfadiazine cream in a wound-healing model.

This review discusses recent findings on the plasticity and regulation of epithelial stem cells and reports no new experimental results.

This article reviews the recognition and management of Staphylococcus aureus toxin-mediated diseases, but it does not present new research findings.

This study found that penetration enhancer-containing vesicles significantly improved minoxidil delivery to the skin compared to traditional liposomes and penetration enhancer-containing ethanolic solutions, with deformability linked to enhanced deposition.

This review discusses the role of the circadian clock in skin functions such as cell proliferation and UV protection and reports no new results; the authors note its potential in studying immune regulation and seasonal behaviors.

This research found that liquid-state liposomes and niosomes may enhance finasteride delivery to pilosebaceous units in hamsters more effectively than gel-state vesicles or hydroalcoholic solution.

This study found that RXRα/RARγ heterodimers are necessary for retinoic acid-induced keratinocyte proliferation in the skin, while normal epidermal maintenance does not require RAR-mediated signaling.

This study demonstrated that stress inhibited hair growth in mice, likely through substance P-dependent activation of immune cells, highlighting a brain-hair follicle connection.

This study found that expressing certain PIN proteins in Arabidopsis root hairs inhibited growth by decreasing auxin levels, while PIN5 slightly stimulated growth, demonstrating differential effects on auxin transport.

The document describes how to tell different types of non-scarring hair loss apart by looking at hair and scalp tissue under a microscope.

This review discusses the potential autoimmune pathogenesis and various contributing factors of alopecia areata, noting that current treatments remain palliative while emerging therapies offer new hope for extensive cases.

This study found that the methanol extract of Eclipta alba showed dose-dependent hair growth promoting activity in pigmented C57/BL6 mice by influencing the transition from the telogen to anagen phase.

This essay discusses the establishment, maintenance, and role of skin stem cells in tissue homeostasis, wound repair, and their relation to skin cancer, without reporting new experimental findings.

This study found that stress increases the number of peptidergic nerve fibers and mast cell activity in mouse skin, suggesting a significant neuro-immune interaction under stress.

This study found that activation or inhibition of Wnt/β-catenin and Notch signaling pathways in rats can alter wound healing, possibly by affecting epidermal stem cell activity and keratinocyte behavior.

This review discusses the potential of ultraviolet (UV) radiation technologies in wound care, highlighting their antimicrobial properties and risks of DNA damage, but reports no new clinical findings.
