This study reported the feasibility of detecting six cell-cycle-related nuclear markers in plucked human scalp and eyebrow hair, providing valuable insights for future intervention studies.

New acne treatments show promise as alternatives to traditional therapies.

Human hair follicles have a unique metabolism that changes between growth stages and may contribute to baldness.

This study found that baicalin activates Wnt/ß-catenin signaling in human dermal papilla cells, increasing alkaline phosphatase expression, growth factor expression, and promoting hair growth in mice.

This article reviews sebaceous immunobiology and highlights the complex role of sebaceous glands and sebocytes in skin barrier function and inflammation, particularly in acne pathogenesis, but reports no new results.

This review discusses skin diseases in transgender patients receiving gender-affirming hormone therapy and procedures, highlighting unique conditions and the underdiagnosis that affects their quality of life and mental health.

This study found that women with female pattern hair loss had increased 5α-reductase isozymes and decreased aromatase mRNA levels, potentially affecting their response to treatment.

This study found that prostaglandin D2 reduced proliferation in bulge resident K15+ stem cells but not in other K15+ progenitor cells, suggesting differential impacts on hair follicle stem cell niches.

This study identified a gene expression signature in mouse embryonic dermal fibroblasts that depends on Wnt/β-catenin activity, potentially influencing dermal fibroblast identity and function.

This review examines the role of hormones in acne pathogenesis, the use of hormonal therapies for treatment, and the importance of contraceptive counseling during isotretinoin therapy, but reports no new clinical results.

This study found that dutasteride completely suppressed the formation of 5alpha-dihydro metabolites in cultured human skin cells, suggesting its potential use in acne and androgenetic alopecia.

This study found that human placental extract promoted hair growth and influenced cellular pathways in vitro and rat models, suggesting potential for future hair loss treatments.

This study established an androgen-responsive human organ culture model using hair follicles, demonstrating that women's intermediate facial follicles grow more hair in response to men's higher androgen levels.

This study found that mechlorethamine restored hair growth in mice with alopecia-areata-like disease by eliminating infiltrated lymphocytes and inhibiting certain pro-inflammatory cytokines in treated skin areas.

This study found that dermal papilla cells from balding follicles exhibit distinct growth characteristics compared to non-balding cells, suggesting their potential as a model for understanding androgenetic alopecia.

This study found that extracellular vesicles from low-passage dermal papilla cells may activate hair growth by delivering miR-140-5p, which downregulates BMP2 signaling, suggesting potential therapeutic targets for alopecia.

This study found that Hoxc13-/- rabbits exhibit complete hair loss on the head and dorsum, providing a potential model for understanding human ECTD-9 and related dermatological conditions.

The study found that finasteride increased endoplasmic reticulum stress and reduced fertility in rats, effects that were alleviated by the administration of DA-9401.

This article reviews emerging opportunities and challenges in male reproductive medicine, including advancements and unmet needs in erectile dysfunction, androgen deficiency, and fertility, but reports no new clinical findings.

The researchers reported that minor salivary gland stem cells exhibit stem cell characteristics and respond to tobacco-derived carcinogens, implicating the transforming growth factor beta pathway in their maintenance.

This article discusses the common dermatological issues in adolescence linked to hormone fluctuations, such as acne and excessive sweating, and reports no new clinical results.

This review discusses strategies to regenerate human hair follicles using stem cells and reports no new experimental results; the authors note existing challenges and the potential of hiPSCs for future applications.

The researchers found that HOXC13 regulates different keratin proteins in a mixed manner, with certain SNPs impeding this regulation, while also demonstrating negative-feedback by HOXC13 and positive regulation by LEF1 and melatonin on the HOXC13 promoter.

This study found that the synthetic thyroid hormone receptor modulator KB2115 significantly prolonged the growth phase of human hair follicles in culture without altering mitochondrial activity, suggesting potential as a safer hair loss treatment compared to traditional thyroid hormones.

This review discusses the cosmetic potential of Southeast Asian herbs and highlights the need for more systematic scientific evaluation of their efficacy and safety.

This study reports that epidermal neural crest stem cells from dogs (cEPI-NCSC) can generate neural crest derivatives and may offer a new cell-based therapy for canine spinal cord injury, with potential as a model for human treatments.

This study found that 6-gingerol, a component of ginger, suppresses hair growth rather than promoting it, both in vitro and in vivo, suggesting potential use in hair removal treatments.

This paper reviews the genetic aspects of hair disorders and suggests that understanding these genes could advance treatment and diagnosis; it reports no new experimental findings.

This article argues that lineage labeling with genetic markers is the gold standard for identifying epithelial stem cells, contrary to the view that in vitro methods alone are sufficient.

This study found that ruxolitinib modulated inflammatory changes and stimulated growth factor signals by blocking the JAK-STAT pathway in an in vitro model of alopecia areata.
