This review examines how epigenetic dysregulation affects adult stem cell function, noting that impacts range from minor to serious disruptions in tissue homeostasis and potential cancer development.

This article discusses advancements in understanding how skin stem cells and fibroblasts contribute to scar formation, highlighting current and potential therapies aimed at preventing or reducing scarring, yet notes that effective treatments without significant side effects are still lacking.

This study found that squamous cell carcinomas from hair follicle stem cells are more prone to epithelial to mesenchymal transition and metastasis than those from interfollicular epidermis, due to distinct chromatin landscapes.

This study found that Wnt signalling activates hair follicle fate in hair follicle stem cells by relieving TCF3/4–TLE-mediated repression, with β-catenin being crucial for this process.

This study found that keratin 17 and TNFα play interdependent roles in regulating hair follicle cycling, with TNFα required for the anagen–catagen transition and its ablation partially rescuing hair cycling defects in K17-null mice.

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.

In this study, researchers found that substance P triggered premature catagen development and immune changes in human scalp hair follicles, providing a possible biological link between stress and hair loss conditions like telogen effluvium and alopecia areata.

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.

This study found that hair follicle patterning in development may arise from a combination of epidermal prepattern signals and mesenchymal self-organisation, with fibroblast growth factor and bone morphogenetic protein activities playing key roles.

This review discusses the cellular and molecular changes involved in cutaneous wound re-epithelialization and EMT, highlighting their similarities and differences, but reports no new clinical results.
