This review explores the hypothesis that polycystic ovary syndrome may originate in fetal life due to genetic predispositions and environmental influences, but it reports no new clinical findings.

This paper reviews the complex pathophysiology of polycystic ovary syndrome, exploring how hormonal and metabolic disturbances contribute to its symptoms and related health risks, but it presents no new findings.

This review discusses the mechanisms and potential therapeutic benefits of mesenchymal stromal cell-derived extracellular vesicles delivered via biomaterials, but reports no new clinical results.

This research discusses how epithelial stem cells in the skin maintain normal homeostasis, contribute to wound repair, and highlights the importance of these processes, as defects can lead to skin diseases including cancers, but provides no new experimental results.

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 article discusses the coordinated roles of different epidermal stem cells and other cell types in the skin's wound healing process and reports no new experimental results.

This review explores recent insights into the diverse cell populations involved in skin development, homeostasis, wound healing, and cancer progression but reports no new results.

This study found that while a tip-focused calcium gradient influences localized growth in root hairs and pollen tubes, it is not the primary determinant of growth direction in root hairs of Arabidopsis thaliana.

This study reviewed recent theories on alopecia areata's pathogenesis, highlighting its autoimmune nature due to immune privilege disruption in hair follicles, and noted current treatments have limited efficacy with high relapse rates, underscoring the need for further research into its mechanisms for better therapies.

In this study, biotinidase deficiency in children usually presented with neurological or skin symptoms, while metabolic ketoacidosis and organic aciduria appeared later.

This study reported that spironolactone at 200 mg/day significantly improved facial hair growth in women with hirsutism and showed a sustained reduction in ovarian androgens over one year.

This review discusses epidermal stem cell diversity, revealing previously unrecognized differences in stem cell populations, but reports no new experimental results; it highlights the need for further exploration of stem cell interactions and quiescence.

This study reviewed clinical data from 60 patients with frontal fibrosing alopecia and found increasing prevalence and generally poor response to treatment, with the cause remaining unclear.

This study found that hair follicle stem cells initially contribute to wound re-epithelialization, but long-lasting epidermal cells are primarily derived from a stem cell population in the isthmus portion of hair follicles.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

This review discusses nonclassical 21-hydroxylase deficiency as the most common autosomal recessive disorder in humans and highlights the effectiveness of glucocorticoid treatment in reversing related symptoms.

This review explores the mechanisms of adult stem cell self-renewal, using skin as a model, and reports no new results but raises important unanswered questions in the field.

This review discusses the immune roles of keratinocytes in wound healing and chronic wound inflammation, emphasizing their potential impact on chronic wound pathology and highlighting areas for future research.

This study reports that mutations in the SUR2 gene are linked to Cantu syndrome, highlighting the role of KATP channels in cardiovascular health and potential new therapies.

This article outlines manifestations of systemic lupus erythematosus, noting rapid joint symptom improvement with corticosteroids and antimalarial drug responsiveness for skin symptoms, and links anti-Ro with photosensitive rash and subacute lupus.

This review discusses the diverse roles and characteristics of epidermal and dermal stem cells in skin regeneration and aging, highlighting their potential applications in regenerative medicine and reports no new clinical results.

This review discusses the dynamic, niche-driven regulation of stem cell states in tissue homeostasis and regeneration, focusing on epithelial stem cells in the mammalian skin, intestine, and lung, without providing 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 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 review examines the literature on the molecular and cellular makeup of the hair follicle niche and how it influences stem cell behavior during hair regeneration, but does not provide new experimental results.

In this study of women with hirsutism or androgenic alopecia, diverse underlying endocrine disorders including polycystic ovaries and various enzyme deficiencies were detected, often associated with elevated testosterone levels.

Different types of stem cells and their environments are key to skin repair and maintenance.

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