Wnt/β-catenin signaling is crucial for cell fusion in placental development.

This review summarizes recent multidisciplinary advances in sebaceous gland research and highlights potential novel therapeutic strategies for skin diseases, but it reports no new clinical results.

This review discusses the genetic factors involved in hair follicle morphogenesis and cycling and reports no new clinical results; it emphasizes the role of genes in hereditary hair diseases.

This review discusses the essential roles and complex regulation of PP2A in various physiological processes and reports no clinical results; the authors highlight the need for further mouse model research to explore PP2A's therapeutic potential.

This study found that deleting the miRNA processing enzymes Drosha and Dicer from mouse skin epithelial cells disrupted normal hair follicle development and maintenance, leading to follicular degradation and stem cell loss during the growth phase.

This review examines PAK4 signaling pathways in prostate cancer, Parkinson's disease, and melanogenesis, focusing on the potential role of the PAK4-CREB axis, without reporting new clinical results.

This review highlights the potential of extracellular vesicle-based therapies for treating various diseases, but it also notes challenges like the lack of regulatory guidelines that hinder their clinical development.

This study found that sympathetic nerves and arrector pili muscles form a niche that modulates hair follicle stem cell activity, revealing their role in hair follicle regeneration.

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 use of Dermal Papilla cells as in vitro models for studying hair growth modulators, emphasizing their role in aiding the development of new hair treatments, but reports no new clinical results.

Four genetic risk spots found for hair loss, with WNT signaling involved and a link to curly hair.

This study found that mice with a specific loss of DNA methyltransferase 1 showed uneven epidermal thickness, reduced hair regeneration, and progressive alopecia, emphasizing DNA methylation's role in stem cell homeostasis.

This review discusses the potential role of steroid 5α-reductase inhibitors in treating neuropsychiatric disorders related to dopaminergic hyperreactivity but reports no new clinical results.

This study found that in vivo, a novel microneedle system for valproic acid delivery may improve hair regrowth efficacy by upregulating hair follicle development pathways more effectively than topical application.

Acne is caused by genetics, diet, hormones, and bacteria, with treatments not yet curative.

Fibroblasts can be turned into melanocytes for potential skin treatments.

This review discusses the role of Toll-like receptors in wound healing and highlights their potential therapeutic value but notes that their role in human wound healing and chronic wounds is not well understood.

This review discusses the biology of hair follicle stem cells and highlights their potential for applications in regenerative medicine, drug, and gene delivery, but reports no new clinical results.

This article discusses Kennedy's disease, detailing its genetic cause, symptoms, and diagnostic criteria, but reports no new clinical findings and highlights a lack of causal therapy.

This study identified 63 genetic loci associated with male-pattern baldness, uncovering genes and pathways that may help develop treatments and suggesting its connection to other human conditions.

The p53 protein has complex, sometimes contradictory functions, including tumor suppression and promoting cell survival.

This review discusses the dermatological adverse events from immunosuppressive and anti-TNF therapy in IBD, finding increased risks of non-melanoma skin cancer and other skin conditions, and recommends regular cancer screening.

This study demonstrates that c-MYC overexpression in sebaceous glands affects differentiation via a regulatory axis involving the androgen receptor and p53, influencing carcinoma formation outcomes.

This study suggests that a position effect disrupting TRPS1 expression may be linked to hypertrichosis in both Ambras syndrome in humans and a similar phenotype in Koa mice.

This review discusses the complex causes and treatment challenges of chronic inflammatory skin diseases, emphasizing the need for biomarkers to predict treatment responses; it reports no new clinical results.

This review discusses the potential role of Wnt signaling in aging-related heart diseases and reports no clinical results.

This study found that male pattern baldness in European males is strongly heritable and associated with genetic markers linked to earlier puberty, bone density, and pancreatic function.

This review discusses various substances that can impact male fertility and stresses that products should be confirmed 'sperm-safe' through rigorous testing, not assumptions; it reports no new study results.

This study found that testosterone and 5α-dihydrotestosterone induced apoptosis in dermal papilla cells from nonbalding scalp regions, suggesting a high androgen stimulus can trigger cell death related to androgenetic alopecia.

This review discusses how androgens may regulate wound healing and inflammation, noting that testosterone appears to inhibit healing and promote inflammation, but it reports no new clinical results.
