This review discusses the mechanisms by which laser treatment affects hair structures and growth, highlighting its potential for permanent hair reduction and associated skin damage, but reports no new experimental results.

This study developed in vitro methods to regenerate hair follicles and erector muscles by mimicking their native structures and mechanical conditions, reconstructing hair follicle-like structures and forming muscle-like tissues.

This review explores the complex interactions between epidermal stem cells and their environment, highlighting the critical roles of these cells in skin wound healing and tissue repair processes.

This review discusses vitamin D and calcium signaling roles in epidermal stem cell processes essential for wound healing but reports no new experimental results, emphasizing their potential interdependent regulatory mechanisms.

This review explores the role of Eph receptors and ephrins in skin cell processes, discussing their potential for therapeutic targeting in dermatological disorders, but it presents no new research findings.

In their 1957 study, Neuman and Neuman suggested that magnesium deficiency may inhibit the ion exchange process required for calcium ions to enter extracellular fluid, potentially affecting calcium mobilization.

This review discusses the role of mTOR signaling in the epidermis, emphasizing its importance in skin processes like barrier formation and wound repair, and reports no new experimental results.

This study observed that the expression of certain keratins during human epidermal development marks the tissue's commitment to stratification and keratinization processes.

This study found that lysine carboxymethyl cysteinate helps protect the epidermis from UVB-induced damage by activating autophagy and restoring cornification processes in a skin model.

This review examines the development of research on the role of the Wnt signaling pathway in the epidermal repair process and reports no new experimental findings.

This study found that infused mouse epidermal growth factor induced wool follicle involution through a quasi-physiological process similar to catagen and a separate pathological action, resulting in fleece 'break' or shedding.

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 article compiles various methods and models for studying keratinocytes, epidermal stem cells, and differentiation processes, but it reports no new research findings.

This study isolated and characterized two distinct types of caspase-like proteases from human epidermis, suggesting their involvement in keratinocyte differentiation and apoptosis processes.

This study found that epidermal stem cell-specific Jag1 expression levels are crucial for effective wound healing and scar reduction, and porcine acellular dermal matrix treatment enhances this process in mice by boosting Notch/Jagged1 signaling.

The study observed that mRAGE expression is prevalent in keratinocytes of the healthy human epidermis and may regulate inflammation and apoptosis to maintain skin homeostasis rather than responding to aging processes.

The researchers reported that autophagy, a lysosome-dependent degradation mechanism, plays a significant role in the cellular remodeling of keratinocyte differentiation in the skin, affecting the properties of the differentiation products by altering cellular components during this process.

This study found that Thy1+ keratinocytes in the basal layer of the interfollicular epidermis play a crucial role in epidermal homeostasis and wound repair, with their ablation impairing these processes.

This study observed that the loss of H3K9me3, via the ablation of Suv39h1, Suv39h2, and Setdb1 in embryonic mouse epidermis, disrupts skin development processes such as keratinocyte differentiation and hair follicle formation, highlighting H3K9me3's crucial role in epidermal morphogenesis.

This study found that p21 is much more highly expressed in normal melanocytes compared to melanoma cells, suggesting a potential target for preventing melanoma progression through cell cycle repair processes.

This study used porcine models to isolate and culture stem cells from brain and hair follicles, shedding light on differentiation processes and potential markers for stem cell compartments under lab conditions.

This study indicates that transient Msx2 expression is critical for wound-induced hair follicle neogenesis, with distinct phases in the healing process essential for epidermal competence and hair regeneration.
