This study identified an unexpected critical role for the FATP4 protein in skin and hair development in mice, linking it to a potential candidate gene for restrictive dermopathy in humans.

This study found that TPA induces apoptosis in pig renal epithelial cells by affecting cell cycle proteins, and activated ras can prevent this process.

This study found that oral tofacitinib significantly reduced alopecia severity and improved quality of life over 12 months for children with moderate to severe alopecia areata, though the authors recommend more research due to the small sample size and absence of a control group.

Enhancing Tregs can protect against alopecia areata.

In this study, three children with severe alopecia treated with systemic tofacitinib showed significant hair regrowth, suggesting it may be a potential option for those unresponsive to conventional therapy.

This case report describes a 43-year-old male with alopecia totalis who successfully regrew all his hair after six months of treatment with tofacitinib, with no relapse at one year.

This study found a specific T cell receptor that may be key in carbamazepine-induced Stevens-Johnson syndrome and toxic epidermal necrolysis, suggesting potential therapeutic targets.

Tofacitinib partially improved hair regrowth in a patient with severe hair loss.

This review summarizes recent advances in understanding the molecular mechanisms of hair follicle formation and discusses potential future clinical applications for treating hair loss and skin tumors, but it reports no new clinical results.

This review discusses the development, lineages, functions, and roles of fibroblasts in fibrosis across four organs, highlighting their capabilities in tissue repair and contributions to fibrotic disorders when aberrantly activated, but it reports no new experimental findings.

This study identified at least four distinct fibroblast populations in adult human skin, each with unique functional properties, suggesting potential therapeutic applications for wound healing and fibrosis-related diseases.

This review discusses the roles of key epithelial-mesenchymal transition factors and potential therapeutic opportunities involving cancer metabolic pathways, reporting no new clinical results.

Nephronectin helps attach muscle cells to hair follicles.

This study found that patterned hair plucking in mice triggers a collective regeneration response in nearby unplucked hair follicles via a quorum sensing mechanism involving immune signaling.

This review discusses the role of epigenetics in colorectal cancer and explains how changes like DNA methylation impact tumor development, but it reports no new results.

In this research, authors found that skin-resident ILCs regulate sebaceous gland function and microbial balance, emphasizing an immune-epithelia system that supports host-microbe symbiosis.

In this study, researchers found that quiescent stem cells resist immune attack due to downregulated antigen presentation, which may help explain the immune evasion of early cancer-initiating cells.

This review discusses the molecular mechanisms involved in hair follicle development and regeneration, highlighting findings from mouse genetic studies, and reports no new experimental results.

This study found that absence of the vitamin D receptor in keratinocytes impairs canonical Wnt signaling and leads to alopecia due to defects in keratinocyte stem cells.

This review examines the role of epidermal stem cells in wound healing, discussing their characteristics and mechanisms, but does not report new clinical results.

In this study, researchers found that extrafollicular progenitors marked by Hic1 are the main contributors to reparative fibroblasts in wound repair, with potential to modulate healing outcomes through genetic and pharmacological interventions.

This review discusses the role of extracellular vesicles in wound healing and explores their potential applications in skin repair and treatment of dermal diseases, reporting no new clinical findings.

This review discusses Wnt signaling pathways in skin development and stem cell regulation, highlighting potential interactions with other pathways but reports no new findings.

This study found that the Wnt inhibitor Dkk4 may play a role in regulating hair follicle development through a feedback loop with canonical Wnt signaling pathways.

This study found that Blimp1 plays a key role in promoting hair follicle morphogenesis and growth by mediating inductive signaling pathways in dermal papilla cells.

This study discovered that a network controlled by the gene p63 is crucial for keratinocyte differentiation and is linked to MYC through cell adhesion-related pathways.

This study found that inhibiting AP-1 activity in mice modified tumor development, leading to transdifferentiation between squamous and sebaceous tumors, with molecular analysis suggesting AP-1's role in maintaining tumor cell identity.

This study introduces a method for long-term expansion of adult mouse epidermal stem cells in vitro using an organoid culture system that maintains the basal-apical organization.

This study found that inactivating CerS4 in mice led to hair follicle stem cell exhaustion and hair loss, indicating its role in regulating hair regeneration through ceramide composition and signaling pathways.
