This study found that direct interactions between human dermal papilla cells and melanocytes under low oxygen conditions improved cell functions and could be important for hair regeneration efforts.

This chapter reviews common drug-related and systemic disorder-induced alopecias, focusing on their epidemiology, causes, symptoms, diagnosis, and treatment, but reports no new findings.

This study found that epigallocatechin-3-gallate (EGCG) may reduce paclitaxel-induced apoptosis in human dermal papilla cells by regulating microRNA expression related to apoptosis and cell proliferation.

This review discusses the state of hair replacement options, highlighting hair transplantation as the gold standard for achieving a natural appearance, and reports no new clinical results.

This study analyzed gene expression data to identify key genes involved in severe forms of alopecia areata, discovering four immune monitoring genes (LGR5, SHISA2, HOXC13, S100A3) with potential for early diagnosis and better understanding of the disease's biological mechanisms.

This review discusses the role of dermal macrophages in stress-induced hair regeneration and reports no new clinical findings, highlighting the need for further research into macrophage dynamics for potential hair loss therapies.

This study suggests that dietary decanoic acid may manage hyperandrogenism and insulin resistance in PCOS, as observed in animal and cell model experiments.

This study demonstrated that blocking S100A3 in mice inhibited hair growth by delaying the anagen phase and reducing the number of hair follicles, suggesting S100A3 as a potential target for hair loss treatments.

This report suggests that recombinant human erythropoietin use may be linked to alopecia in Southeast Asian women with chronic renal failure.

In this study, 60 mg/day of Cepharanthine significantly reduced the time to a negative COVID-19 test among de novo infected patients with good compliance, though 120 mg/day showed no such effect.

This study investigated the safety and effectiveness of two thioglycolate chemical depilatory creams for full genital hair removal in men and women, finding acceptable dermal tolerance despite some instances of irritation, supporting their use for pubic hair grooming.

In this study, the size of vaginal prolapse was significantly linked to preoperative vaginal length and the length of vaginal excision following the Michigan four-wall sacrospinous suspension.

This study observed that the size of vaginal prolapse in patients was significantly related to both the preoperative vaginal length and the length of vaginal excision during the Michigan four-wall sacrospinous suspension procedure.

This review summarizes the cell type distribution and functional significance of human keratins, emphasizing their roles in tumor diagnosis and potential clinical applications, and reports no new clinical findings.

This review discusses the reuse of molecular mechanisms involved in embryonic skin development for maintaining adult epidermal homeostasis and reports no new results.

This review summarizes how genetic studies using conditional β-catenin loss- and gain-of-function mice have advanced understanding of canonical Wnt signaling's role in embryonic development, adult stem cell maintenance, and cancer modeling.

This study found that Tcf3 and Lef1 differently regulate cell differentiation in multipotent skin stem cells, with Tcf3 promoting follicle-like features and Lef1, when modified, promoting sebocyte differentiation.

This study reports that NIH PCOS is linked to more severe metabolic issues, including higher obesity and insulin resistance, compared to non-NIH PCOS phenotypes.

This study found that apple polyphenol extract, particularly oligomeric procyanidins, inhibited pancreatic lipase activity and reduced triglyceride absorption in both mice and humans.

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 review discusses the role of stem cell progeny as integral components of stem cell niches, offering feedback that may influence different stem cell systems' microenvironments, but it presents no new research findings.

This review discusses the regulation and function of vitamin D and its receptor in skin cells, highlighting their roles in processes such as proliferation inhibition, differentiation, and innate immunity, but reports no new results.

This review covers recent findings on stem cell plasticity under normal and cancerous conditions but presents no new experimental results, highlighting implications for regenerative medicine and cancer treatments.

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 combined loss of Atr and p53 in adult mice led to severe tissue degeneration and delayed regeneration due to the accumulation of highly damaged cells.

This study reports that overexpressing the BMP antagonist noggin in mice inhibits eyelid opening by reducing apoptosis and delaying cell differentiation in the eyelid epithelium.

This study found that plasmacytoid dendritic cells are central to the pathogenesis of alopecia areata, suggesting they may help differentiate it from trichotillomania and androgenetic alopecia.

This article examines the role and composition of integral hair lipids in forming a protective barrier similar to the skin's epidermal lipid layer and reports no new findings about their effects.

This study suggests that higher PDCD4 expression may play a significant role in polycystic ovary syndrome pathogenesis through its association with obesity, insulin resistance, lipid metabolism disorders, and increased granulosa cell apoptosis.

In this study, mouse amnion epithelium was successfully transformed into skin and hair follicles when associated with hair-forming dermis, revealing the necessity of specific influences for follicle formation.
