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

This study found that keratin 19 may be a marker for skin stem cells, helping to characterize these cells in different conditions and potentially explaining variations in healing rates between children and adults.

This study found that dutasteride more effectively reduced serum dihydrotestosterone levels than finasteride in patients with benign prostatic hyperplasia.

In this study, researchers linked defects in U2HR, an inhibitory region in the HR gene, to Marie Unna hereditary hypotrichosis, suggesting a mechanism for controlling hair growth and addressing hair loss.

This study found that hair follicle-derived dermal stem cells and bone marrow mesenchymal stem cells have similar growth, differentiation capabilities, and surface marker expressions, suggesting hair follicles could be accessible sources for mesenchymal stem cells.

This study found that C8/144B antibody exclusively binds to the hair follicle bulge and not the epidermal stratum basale, with cytokeratin 19 serving as a key marker of certain basal keratinocytes that decrease with age.

This study found that the vitamin D receptor in lampreys, which lack bones and hair, binds 1,25-dihydroxyvitamin D3 and may function to induce enzymes for detoxifying substances.

This review discusses various stem cell compartments in adult murine and human epidermis, examining their expressed markers and characterization assays, and reports no new experimental results.

This study found that traction alopecia risk was higher in adults than children and increased further when traction was combined with chemically relaxed hair.

This study found that labeled galectin-1 binds to specific nuclear sites in human bone marrow stromal cells and keratinocytes, suggesting a role in nuclear function, although only in a small fraction of cells.

This study provides further evidence for a genetic basis of PCOS, showing that polycystic ovarian morphology is a marker of inherited biochemical features in families with PCOS.

This study identified a subtype of itch-sensing neurons in mice, which express Ret and somatostatin, and found that their ablation reduces scratching induced by certain pruritogens.

This study found that the absence of Ctip2 in epidermal keratinocytes led to impaired wound healing in mice, affecting cell migration, proliferation, and hair follicle stem cell maintenance.

In this study, researchers reported that about one-third of men with premature alopecia displayed hormonal shifts and higher insulin resistance, resembling the prevalence pattern of PCOS in women.

This text is an informational content piece about JAMA Dermatology's website and does not contain any research findings or conclusions.

This study identified a distinct gene near the hairless locus on chromosome 8p that is responsible for hereditary Marie Unna type hypotrichosis in a German family.

The gene for Marie Unna hereditary hypotrichosis is located on chromosome 8p21.

This study found that men with early-onset androgenetic alopecia had significantly larger prostate volumes and lower urinary flow rates compared to healthy controls, suggesting a possible link between AGA and prostate-related urinary symptoms.

This study found that a marine-extract dietary supplement significantly reduced hair shedding and increased hair diameter in premenopausal women with subclinical hair thinning or hair loss after 6 months of use.

In this study, the researchers reported extensive gene loss and high pseudogenization rates of α-keratin genes in cetaceans compared to terrestrial mammals, likely linked to hair loss and aquatic adaptations.

This study found that a marine complex supplement significantly reduced hair shedding and increased hair growth in men with thinning hair over 180 days.

This study found significant differences in scalp microbiome composition and volatile organic metabolites between individuals with alopecia areata and healthy controls, suggesting potential microbiome-related therapeutic interventions for hair growth disorders.

This study found that an oral marine protein supplement significantly increased hair growth and reduced hair shedding in women with temporary thinning hair over 90 days compared to a placebo.

This study describes a mouse model for Marie Unna Hereditary Hypotrichosis, identifying mutations in the hairless gene that result in sparse or absent hair and cyst-like hair follicles.

This article discusses advances in hair restoration surgery techniques but reports no new findings, noting potential challenges for new surgeons who face increased demands in time and labor.

In this study, women with PCOS who took 12 mg of Astaxanthin daily for 8 weeks showed a reduction in certain inflammatory markers and apoptosis-related genes, suggesting potential benefits for managing PCOS, though effects on symptoms like BMI and hirsutism were not significant.

This study explores the potential of seaweeds as a source of bioactive compounds for food, cosmetics, and medical applications, while highlighting concerns about toxic element accumulation and suggesting purification and nanoencapsulation techniques to enhance safety and stability.

This study introduces a new multimodal imaging technology to visualize and quantify cell dynamics in natural skin over long durations, demonstrated in GFP bone marrow-transplanted mice, to study dynamic skin regeneration.

This study discusses the rise of commercial direct-to-consumer stem cell therapies, highlighting how they are marketed as biomedical 'lifestyle' products that blend science, medicine, and consumer culture, despite ongoing safety and efficacy concerns.

This study found significantly higher levels of the protein ULBP3 in patients with alopecia areata incognita compared to other hair loss conditions and healthy controls, suggesting ULBP3's potential as a diagnostic marker for AAI.
