This review examines the roles of adenosine and caffeine in regulating hair growth cycles but reports no new results, highlighting unanswered questions about their specific mechanisms.

This study found that thyrotropin-releasing hormone (TRH) acts as a potent stimulator of hair growth in human scalp hair follicles, promoting elongation and prolonging the anagen phase.

This review discusses the heterogeneity and plasticity of epithelial stem cells in skin homeostasis, wound healing, and tumorigenesis, reporting no new results but emphasizing the need for further exploration of key regulatory mechanisms.

In this study, Ser516 phosphorylation of Artemis was found predominantly in the outer root sheath keratinocytes of hair follicles, suggesting a role in regulating human epidermal appendages.

This study suggests that human scalp hair follicles express erythropoietin and its receptor, up-regulating receptor expression under hypoxic conditions, and may mimic another hypothalamus–pituitary axis equivalent involving the TRH-TSH system.

The study found that prolactin expressed in human scalp hair follicles acts as an autocrine modulator, inhibiting hair growth and promoting hair follicle regression, which may contribute to hair loss in hyper-prolactinemia patients.

This study found that peach kernel oil extracted via supercritical fluid extraction had higher quality and antioxidant properties than oil obtained by other methods, effectively protecting human hair follicle keratinocytes from oxidative damage.

This study found no significant differences in hormone levels between postmenopausal women with androgenetic alopecia and healthy controls, suggesting potential alternative causes for the condition.

The document concluded that stem cells are crucial for skin repair, regeneration, and may help in developing advanced skin substitutes.

In this study, researchers found that transgenic expression of the Hairless gene in keratinocytes can restore hair follicle regeneration in Hr-deficient mice by repressing Wise, a modulator of Wnt signaling.

This article discusses the structure and function of the skin's layers, cell types, and tumor development, without reporting new clinical findings, and highlights the growing incidence of skin cancer.

This article discusses the structure and function of the skin, the etiology and increasing incidence of skin cancer, and the types and prevalence of malignant skin tumors, but reports no new research findings.

This review discusses the role of the mineralocorticoid receptor in skin biology, highlighting its potential involvement in keratinocyte and hair physiology, and proposes it may affect the side effects of glucocorticoid use.

This review focuses on the role of the transcription factor Foxn1 in skin biology and discusses its potential implications for regenerative medicine, but reports no new clinical results.

This review discusses the therapeutic potential of mesenchymal stem cell-derived small extracellular vesicles for chronic wound treatment and reports no new clinical results, emphasizing the need for further research on their large-scale production and engineering.

In this animal study, researchers found that the simultaneous deletion of ERBB2 and ERBB3 in mice results in impaired skin differentiation, inflammation, and sebaceous gland alteration, leading to skin lesions, while highlighting potential side effects in cancer therapies targeting these receptors.

The research found that while Dnmt3a and Dnmt3b are not necessary for skin homeostasis in mice, the loss of Dnmt3a increases squamous tumor formation from carcinogens, and combined deletion of both results in more aggressive and metastatic tumors.

This study found that hair follicle stem cells from mice can differentiate into beating cardiac muscle cells, suggesting potential applications for heart regeneration in regenerative medicine.

This study found that treating human dermal fibroblast cells with ginsenoside Rd increased the expression of mRNA associated with the dermal-epidermal junction, suggesting potential as an anti-aging cosmetic ingredient.

This study found that the enzyme Acer1 plays a crucial role in skin health and tumor prevention by regulating ceramide metabolism in mice.

This review discusses the use of bioactive glass in skin tissue repair and highlights its potential to aid wound healing through effects on inflammatory cells and tissue regeneration, but reports no new experimental findings.

This perspective reviews current knowledge about cellular and molecular mechanisms in wound healing from 2023–2025, highlighting inadequately understood pathways associated with conditions like keloids and chronic wounds, and discusses proposed novel therapies for these conditions.

This study found that ATM protein plays a crucial role in protecting human hair follicle melanocytes from oxidative stress, which is linked to the greying of hair.

This study found that the distribution of desmogleins is associated with specific types of keratinization and hair anchorage, as well as hypotrichosis.

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 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 study suggests that vitamin D-upregulated protein 1 (VDUP1) might play a unique role in regulating the differentiation of epidermal cells.

This study found that Plakophilin 1 regulates innate immune responses in keratinocytes by controlling RNA helicase activity, balancing inflammation during epidermal immune challenges.

This paper presents a new methodology combining magnetic tweezers and traction force microscopy to study keratinocyte mechanobiology, but reports no experimental results yet.

The researchers reported that in nonmelanoma skin cancers, the expression of osteopontin splice variants is significantly higher compared to normal skin, with OPN-a elevated in basal cell carcinoma more than OPN-c.
