This study found that conditional knockout of N-WASP in keratinocytes of mice led to skin barrier defects, increased immune cell infiltration, and hyperproliferation of keratinocytes, indicating its crucial role in skin homeostasis.

This review discusses the identification and roles of different epidermal stem cell types in skin homeostasis and repair, and reports no new experimental findings.

This study observed that NSPC predominantly differentiated into neurons when exposed to serum fractions with molecules under 100 kDa, particularly with biomaterial and fibronectin, in the presence of basic fibroblast growth factor.

This study found that Frizzled genes Fzd3 and Fzd6 are redundantly involved in controlling hair follicle polarity in mice, but operate through distinct mechanisms, highlighting their complex role in hair orientation.

This article reviews the therapeutic use of interferons and other cytokines in various viral, tumorous, and inflammatory diseases, discussing their biological effects and potential future applications without presenting new experimental results.

This article reviews sebaceous immunobiology and highlights the complex role of sebaceous glands and sebocytes in skin barrier function and inflammation, particularly in acne pathogenesis, but reports no new results.

This study found that adipose-derived mesenchymal stem cells from type 2 diabetes mice were slightly less effective, yet had comparable therapeutic effects on wound healing compared to non-diabetic controls.

This review discusses recent advancements in regenerative medicine, including functional organ regeneration and the creation of mini-organs, and reports no new clinical results.

This study found that synthetic melanin particles applied topically in mouse injury models improved wound healing, showing potential as a therapy for accelerated healing, including in human skin explants.

This study found that silk fibroin gel induced more pro-regenerative macrophages and hair follicle stem cells, leading to almost scarless skin regeneration compared to alginate gel.

This review discusses the migration and colonization of melanocytes from the neural crest in mammals and reports no new experimental results.

In this study, researchers developed a method to efficiently derive contractile smooth muscle cells from human hair follicle stem cells using TGF-β1 and PDGF-BB, which may advance vascular tissue engineering.

This review discusses recent advances in understanding Merkel cell carcinoma biology, including the development of genetically-engineered mouse models and potential therapeutic targets, but reports no new clinical results.

In this study, the researchers discovered that specific polyamine depletion enhances stemness in hair follicle stem cells through a mechanism independent of mRNA translation.

This study found that a 3D co-culture of endothelial colony-forming cells and adipose-derived stem cells restored stem cell properties and improved healing in a mouse model of chronic injury.

In this case report, two plywood mill workers developed allergic contact dermatitis due to exposure to uncured phenol-formaldehyde resin, not sawdust as initially suspected.

In this study, a novel homozygous mutation in the STAT5B gene was identified in a 17-year-old boy with growth hormone-refractory growth failure, severe eczema, and autoimmune disease, suggesting a similarity to known STAT5B deficiency phenotypes.

This study found that in mice, low-dose irradiation causes stem cells in hair follicles to undergo chromatin alterations, which may eventually lead to long-term functional loss in tissues or organs.

This study found that low-level laser therapy increased the expression of proteins in dermal papilla tissues, suggesting it promotes hair growth in male androgenetic alopecia patients.

This study observed that adipose-derived stem cells modified with trichogenic factors have similar properties to dermal papilla cells and show enhanced hair regeneration potential compared to unmodified adipose-derived stem cells.

This study observed that dermal papilla cell aggregates showed increased viability and gene expression on softer 3D substrates, indicating the importance of substrate stiffness in cellular behavior.

In this study, basal cell carcinoma developed in Ptch-deficient mice only after chemical treatment, not skin wounding, suggesting a second unknown event is necessary for tumor formation.

This review discusses the molecular mechanisms driving hair follicle degeneration in skin aging and emphasizes the role of the tissue microenvironment on stem cell function, but reports no new research findings.

This study reveals that β-catenin and retinoic acid are key regulators in the gene networks controlling the fate of skin appendages, such as scales and feathers.

This case report describes an 80-year-old patient whose scalp wound healed by secondary intention, with unexpected hair regrowth observed at 180 days, suggesting hair neogenesis is possible even in older adults.

This review highlighted that in an in vitro setting, 3D spheroid cultures of fish cells offer a promising alternative to traditional monolayer cultures, potentially advancing research in eco-toxicology, immunology, drug screening, and more by better mimicking in vivo conditions.

Lower GATA3 levels in mice help hair regrow by changing certain immune cells.

In this study, umbilical cord mesenchymal stem cell-derived apoptotic extracellular vesicles were found to improve wound healing in type 2 diabetic mice by inhibiting macrophage pyroptosis and reducing oxidative stress levels.

This study found that pelage abnormalities in Harlequin mutant mice are linked to severe AIF deficiency and associated with altered expression of genes related to hair structure.
