This study found that mutations in the Foxn1 gene in nude mice affect not only hair but also nail structure and differentiation, offering insights into nail hypergranulosis pathogenesis relevant to human nail diseases.

This article reviews methods to enhance epithelial–mesenchymal interactions for hair follicle bioengineering but does not present new experimental results; it emphasizes optimizing combinations for successful regeneration.

This study found that permanent alopecia can occur after certain chemotherapy treatments and presents as nonscarring hair loss similar to androgenetic alopecia, with specific histological features that could be misdiagnosed without proper clinicopathological correlation.

This research observed that dermal papilla cells have the potential to regenerate hair bulbs under preferred environmental conditions when associated with dermal sheath cells or exposed to specific growth factors.

This review discusses recent advances in scarless wound healing, focusing on strategies to create pro-regenerative scaffolds for repairing damaged skin, and reports no new clinical results.

In this study, UVB irradiation of organ-cultured human anagen hair follicles in vitro reduced hair elongation and increased cell death, affecting hair growth and regulatory processes.

This study found that human hair follicle stem cells formed more colonies and adhered more rapidly, while transit-amplifying cells showed significantly greater mobility.

This review discusses the enhanced understanding of how stem cell niches respond adaptively to systemic signals, aging, and local perturbations, but reports no new research findings.

In this study, red ginseng extract and its ginsenosides enhanced human hair follicle cell proliferation and countered dihydrotestosterone-induced suppression, suggesting potential to promote hair growth.

This review explores the diverse roles and heterogeneity of fibroblasts across different organs, highlighting their potential involvement in both normal tissue functioning and fibrotic diseases, but reports no new experimental results.

This study suggests that loss of DMBT1 and galectin-3 expression may contribute to the development of epithelial skin cancers, indicating potential tumor-suppressive roles in this context.

This study found that maintaining tension-force balance in a human skin equivalent improved characteristics of skin homeostasis and structure, suggesting potential as an alternative to animal models for studying skin physiology.

This study demonstrated that OSA hydrogels enhanced the stability and retention of dermal papilla-derived extracellular vesicles, which significantly improved hair regeneration in both cultured human hair and a mouse depilation model.

In this study, researchers found that changes in the extracellular matrix components, particularly fibronectin, laminin, and type IV collagen, during the rat vibrissa follicle growth cycle, suggest dynamic remodeling related to dermal-epidermal signaling.

This study found that using 3D dermal papilla spheroid models enhances extracellular matrix production and hair follicle marker expression, providing insights into hair follicle biology and potential for drug screening.

This study identified hair shaft progenitors in the matrix that regulate hair growth and pigmentation by creating a niche dependent on stem cell factor, implicating KROX20+ cells in these processes.

This study identified several DPC-specific proteins, including ITGB1, IGFBP3, and THBS1, as potential biomarkers for hair growth modulation through proteomic and network analysis.

This study found that autophagy plays a novel role in human hair growth, with altered autophagic flux during hair development phases influencing hair follicle behavior in a preclinical model.

This study found that while extracellular matrix components like hyaluronic acid promoted larger organoid formation, other matrix components hindered hair follicle germ assembly in an in vitro model.

This study observed that PAI-2 is consistently expressed in differentiating cells of murine hair and nail, suggesting it may function as a marker of differentiation and possibly protect against premature cell death.

This review examines the differentiation potential of epithelial cells from various sources in hair follicle formation, concluding that complex interactions are required for hair-specific characteristics, which were achieved in vivo but not in vitro.

This review discusses the role of fascial mobilization in wound healing and its potential implications for treating chronic skin wounds and scarring, but reports no new clinical results.

In this study, the researchers identified the specific subcellular localization of the protein S100A3 in the endocuticle and cortex of human hair shafts.

This study reported that exposure to 1,763 MHz radiofrequency radiation stimulated hair growth in vitro by inducing insulin-like growth factor-1 expression in cultured human dermal papilla cells.

In this study, researchers detailed how hair follicles regenerate after microsurgical amputation, observing a wound reaction involving dynamic dermal-epidermal interactions and changes in extracellular matrix components.

This study developed electrospun nanofibers containing mupirocin for wound treatment, reporting enhanced antibacterial activity, high water absorption, and accelerated wound healing in a rat model, suggesting potential use for severe skin injuries at risk of infection.

This study suggests that IL-1β produced by dermal papilla cells, regulated by protein kinase C, may inhibit human hair follicle growth through paracrine signaling.

This study suggests that the action of minoxidil in stimulating hair growth likely occurs at the follicular dermal papilla, though it does not induce new follicle formation.

This study identified a nonsense mutation in the zinc-finger domain of the hairless gene associated with congenital atrichia in a Japanese family, indicating a potential genetic cause for this rare form of alopecia.

This study found that specific histologic features in skin biopsies can help support a diagnosis of traumatic alopecia (trichotillomania), but not all markers are distinct to the condition.
