This study found that the subtilisin protease Sub3 from Microsporum canis is essential for adherence to the feline epidermis but is not necessary for invading epidermal structures.

This review highlights the significance and future potential of forensic DNA phenotyping for predicting human phenotypes from crime scene DNA but reports no new results.

This review discusses the potential markers for identifying and studying stem cells in the epidermis and hair follicles, highlighting their role in understanding skin disease pathogenesis and expanding therapeutic options, but reports no new findings.

This review examines beta-catenin's role in stem cell renewal, lineage selection, and tumor formation in the epidermis and reports no new experimental findings.

This study found that combining adult germinative epidermal cells with non-inductive dermal cells can stimulate hair follicle neogenesis, effectively altering the cells' status to enhance induction.

This review examines the location and markers of hair follicle stem cells, finding that they are primarily located in the bulge region and can contribute to various skin structures, but challenges remain in distinguishing them from their progeny.

This study found that RANK-RANKL signaling regulates hair renewal and epidermal homeostasis in mice, revealing its role in initiating hair growth cycles and maintaining skin cell activity.

In this study, TCDD administered to male rats down-regulated EGF receptor in liver plasma membranes and increased protein kinase activity, suggesting EGF receptor–mediated toxicological effects.

This study found that the zinc transporter ZIP10 is crucial for epidermal development, as it influences the activity of p63, promoting epidermal morphogenesis.

This study mapped the safety profile of EGFR-TKIs by analyzing FDA adverse event reports, highlighting unexpected reactions like intestinal obstruction and hypokalaemia with gefitinib and erlotinib.

This study found that epidermal and fibroblast growth factors increased proliferation of human hair bulb papilla cells and root sheath fibroblasts in vitro, while hydrocortisone decreased it and minoxidil had no effect.

This review highlights recent advances in understanding how the extracellular matrix regulates epidermal stem cell fate, emphasizing the importance of the hair follicle stem cell niche, but reports no new empirical findings.

This study found that the absence of laminin α5 in adult mice's epidermal basement membrane led to keratinocyte hyperproliferation and immune cell changes, affecting hair follicle development through altered growth factor expression.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

This case report describes a woman who developed extensive nonscarring inflammatory hair loss after two years of gefitinib treatment, highlighting potential cutaneous side effects associated with epidermal growth factor receptor blockers.

Cathepsin L deficiency causes hair and skin issues in mice.

This study found that H-Ras activation in aged mouse skin leads to increased dysplasia and progression to in situ squamous cell carcinoma, highlighting an age-linked connection between immune changes, senescence, and cancer risk.

This study suggests that the susceptibility of hair follicle melanocytes to oxidative stress as they age may be key in the graying of hair due to reduced catalase expression and activity.

This article discusses various types of epidermal nevi and associated syndromes but presents no new research findings.

This study identified altered expression of MMP-19 in the skin's epidermal layers during diseases like psoriasis and eczema, implying a role in disease processes.

This study used electron microscopy to identify a distinct dendritic cell in the human epidermis, similar to the melanocyte, with unique structural features and variable melanin content.

Research on epidermal stem cells has advanced significantly, showing promise for improved clinical therapies.

This study reports that corneal transient amplifying cells can be reprogrammed into epidermal cells capable of forming hair follicles in response to embryonic dermis signals.

This study found that different epidermal stem cell populations contribute to the formation of various skin tumors and new hair follicles following β-catenin activation in the adult epidermis.

In this mouse study, the researchers found that the monoclonal antibody ME1 causes hair follicle inflammation by up-regulating TNFα, which can be reduced by TNFα and interleukin-1 inhibitors.

In this study, expressing human K16 in the epidermis of K14 null mice prevented early skin blistering but led to age-related anomalies, indicating K16 and K14 have distinct roles despite their sequence similarity.

This study reports that human epidermal transglutaminase activity increases with treatment using organic solvents and chemicals without significant molecular weight changes, which may allow modulation of the enzyme in skin diseases.

Injecting lentiviral vectors into early gestation mice effectively targets skin stem cells for potential gene therapy.

This study found that ablating centrosomes in developing epidermis alters keratinocyte division without majorly affecting differentiation, suggesting early epidermal development is driven by high proliferation and cell delamination.
