This review describes the roles of 5α-reductase isozymes in prostate development and pathology and reports no new clinical results.

This review discusses the role of dietary habits and lifestyle modifications in managing polycystic ovary syndrome and reports no clinical results; the authors emphasize the need for tailored diet therapy in affected women.

In this study, a novel mutation in the glucocorticoid receptor gene was identified in a young woman, impairing glucocorticoid signaling and leading to generalized glucocorticoid resistance.

This study found that metformin treatment significantly improved hair growth in women with PCOS and hirsutism compared to a placebo.

This study found that PCL-based nanofiber scaffolds enhanced cell proliferation and extracellular matrix deposition, suggesting they show promise as a cell delivery system for improving skin wound healing.

This study found that simultaneously inhibiting both KLK5 and KLK7 proteases completely rescued skin barrier defects in a mouse model of Netherton syndrome, suggesting both should be therapeutic targets.

This review discusses different preparation and application methods of platelet-rich plasma in dental regenerative medicine and reports no new results, highlighting its potential and associated controversies.

In this study, researchers found that TCDD exposure accelerated differentiation and altered gene expression in human epidermal cells, indicating the epidermal barrier as a target of TCDD-activated AHR.

This review discusses the role of circadian rhythms in stem cell differentiation and tissue regeneration, emphasizing their impact on organ physiology and aging, but reports no new experimental results.

This study found that epidermal Wnt production is crucial for forming the skin's spinous layer through a BMP-FGF signaling cascade, although Wnt from basal cells is not needed for their differentiation.

This review discusses strategies for regenerating cutaneous nerve function in burn patients and highlights the potential role of autologous skin-derived adult stem cells in improving sensory recovery, but reports no new experimental findings.

This study found that downregulation of EGF and KGF signaling is necessary for hair follicle initiation in placodes, revealing a new role for KGF in hair follicle formation in mice.

This study describes the enzymatic processes through which DHEA is converted to active sex steroids in human skin, highlighting an androgenic effect on sebaceous glands and estrogenic effects in the vagina.

This study found that activin affects both stromal cells and keratinocytes in skin morphogenesis and repair, with dose-dependent effects on keratinocytes demonstrated through transgenic mouse models.

This study suggests that the GPX-PDE1 and GPX-PDE2 genes in white lupin enhance root hair development and contribute to Pi limitation acclimation by facilitating glycerophosphodiester degradation.

This review discusses the development and future prospects of biomaterials for in situ tissue regeneration but reports no new research results; it underscores the importance of biomaterials in addressing tissue defects.

This review discusses the use of biotin for hair and nail growth, noting clinical improvement in cases with existing pathologies, but concludes there is insufficient evidence supporting its benefits for healthy individuals.

This review examines the skin exposome, including solar exposure, air pollution, hormones, nutrition, and psychological factors, but reports no new clinical results.

This article reviews the effects of various medications on male fertility, noting that while commonly used drugs can mostly have reversible impacts, conclusive human evidence remains limited.

This study observed specific expression patterns of three zebrafish estrogen receptor genes during development, highlighting robust co-expression of esr2a and esr2b in primary neuromasts, branchial arches, and other tissues.

This study details the isolation and characterization of the human type II 5 alpha-reductase gene, which may play a role in male pseudohermaphroditism, prostate cancer, and benign prostatic hyperplasia.

This review discusses the diagnosis, treatment, and management of atopic dermatitis in developing countries and identifies significant unmet medical needs, particularly in access to care and effective treatments; it reports no clinical results.

This article reviews the role of stem cells in tissue development, tumor formation, and organoid generation, and highlights the potential of epigenetic regulation in advancing regenerative medicine and cancer treatment, without presenting new experimental results.

This review discusses the relationship between estrogen deficiency and skin aging in postmenopausal women, noting potential benefits of estrogen use on skin collagen and elasticity, but reports no new clinical results.

This review discusses the use of dermal regeneration templates for treating burn injuries and other wounds, highlighting their effectiveness in reducing scars and aiding in regenerative processes, but reports no new clinical results.

This review identifies shared interferon gamma-driven immune pathways in vitiligo and alopecia areata, revealing potential targets for new treatments, but reports no clinical results.

This review examines the role of Hairless, a nuclear receptor corepressor, in regulating Wnt signaling during hair cycling and reports no new clinical results.

This study discovered nine human type I hair keratin genes, including a transcribed pseudogene, in a 190 kbp genomic region, revealing three gene subclusters based on sequence homologies.

This study reported that men with more significant hair loss experience greater negative psychosocial effects, particularly noticeable in younger age groups.

This study found that human hair follicle-derived mesenchymal stem cells can differentiate into myogenic, osteogenic, adipogenic, and chondrogenic lineages, although this potential decreases over time and varies by lineage.
