Recognizing new allergens can help reduce contact dermatitis cases.

This review discusses the relationship between vitamin K and osteoarthritis, noting that while lower vitamin K levels are associated with increased osteoarthritis, the effects of vitamin K supplementation on the condition remain unclear due to a lack of clinical trials.

This review covers dermatological conditions experienced by ice-skating athletes due to cold exposure, infections, and inflammation, providing no new clinical findings and emphasizing diagnosis and treatment strategies.

Lgr5 is a marker for active, long-lasting stem cells in mouse hair follicles.

This review discusses the biochemical and biological functions of histone demethylases and their potential involvement in human diseases, including cancer, but reports no new findings.

This study found that intradermal adipocyte lineage cells in mice are necessary and sufficient to activate follicular stem cells, highlighting their role in regulating skin stem cell activity.

This study developed molecular signatures for dermal papilla cells and their niche, uncovering novel signaling regulators and genes linked to hair disorders, which may inform future hair development research.

People with hair loss have more androgen receptors and enzymes in certain follicles, with men and women showing different patterns.

This study found that super-enhancers are essential for hair follicle stem cell identity, lineage commitment, and plasticity in mice, with SOX9 being a key regulator of these chromatin dynamics.

This study found that induced expression of mir-302 can reprogram human hair follicle cells into induced pluripotent stem cells through a novel epigenetic mechanism involving global demethylation.

This study reports that hair regeneration in live mice involves spatially regulated stem cell divisions and requires mesenchymal interactions, observed in real-time using a novel non-invasive imaging method.

This review discusses the links between particulate matter exposure and skin diseases, highlighting oxidative stress and inflammation as key mechanisms; it reports no new clinical results.

This study found that the circadian clock regulates the activation state of murine epidermal stem cells, affecting tissue homeostasis and susceptibility to tumorigenesis when disrupted.

This study found that TRPA1-deficient mice exhibited normal cold sensitivity but had decreased mechanical response in nociceptors, suggesting TRPA1's role in mechanotransduction.

In this study, homozygous VDR null mutant mice exhibited nonfunctional vitamin D receptors, leading to growth abnormalities and revealing the limited physiological importance of vitamin D pathways outside the classical receptor.

This study found that adipocytes play a crucial role in skin wound healing by facilitating fibroblast recruitment and dermal reconstruction during the healing process.

This review discusses the biochemical properties and clinical significance of 5 alpha-reductase isozymes and reports no new clinical results.

This study identified a set of wound-induced genes in planarians that play a role in regeneration initiation, with some genes specifically activating within regenerative cells called neoblasts.

This review discusses recent advances in skin penetration mechanisms, specifically focusing on the enhanced understanding of the follicular pathway and its implications for transdermal therapies, immune system targeting, and nanoparticle safety.

This review examines hair cosmetics, including shampoos and conditioners, for their formulations and effects, but reports no new clinical findings; it emphasizes the importance of dermatologist knowledge in treating diverse hair conditions.

This study found that polycomb-group-mediated repression plays a key role in regulating hair follicle stem cell states and lineage progression by distinct mechanisms in adult mouse skin.

This review discusses strategies for developing semi-solid topical generic products to match the quality of reference-listed drugs, using concepts like quality by design and reverse-engineering, but reports no new results.

This study found that adipose-derived mesenchymal stem cells produced more anti-inflammatory and pro-angiogenic cytokines on electrospun scaffolds, which enhanced wound healing and macrophage activity in a rat model.

This study found that Cutl1 mutant mice experienced retarded lung differentiation and abnormal hair follicle morphogenesis, indicating the vital role of CDP in lung development and hair follicle cell-lineage specification.

This study introduces a novel non-invasive method called "differential stripping" to quantify the penetration of topically applied substances into hair follicles.

This study found that different stabilizing mutations in Aux/IAA proteins affect root hair development in Arabidopsis by disrupting the auxin response and suggest a model where the relative abundance of these proteins determines root hair initiation.

This study found that keratin K14 expression occurs early in epidermal cell differentiation, while a hair-specific keratin is expressed later in hair matrix cells, suggesting developmental divergence between the two cell types.

This study found that cathepsin L deficiency in mice led to significant abnormalities in hair follicle development and cycling, including disrupted hair shaft outgrowth and premature hair growth phase entry.

This article discusses the potential benefits of safflower in traditional Persian medicine for various conditions and highlights the need for comprehensive phytochemical research, without reporting new clinical results.

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.
