This study found that AP-2α and AP-2β transcription factors are crucial for maintaining adult skin homeostasis, with their inactivation in keratinocytes leading to impaired differentiation, hair abnormalities, and inflammation, highlighting their key regulatory roles.

In this review paper, the authors explored the composition and role of lipids in human hair, highlighting their importance for hair texture, moisture retention, and tensile strength, while noting that the understanding of hair lipids' functions remains controversial and requires further research.

In this study, researchers found that in growing skin tissue, epidermal wound healing occurs at the expense of normal skin development, as it impairs hair follicle growth and does not activate tissue morphogenesis genes.

This review discusses the roles and characteristics of skin stem cells, their niches, and signaling pathways in skin maintenance, aging, and cancer, highlighting their potential in therapeutic applications but presenting no new clinical findings.

This chapter reviews therapies for skin and corneal regeneration and hair loss, discussing various treatments but presenting no new research findings.

In this review, researchers summarize key factors in constructing skin organoids, including cell source and assembly methods, and emphasize advances such as air-liquid interface culture for improving tissue development, aiming to guide standardized protocols and future clinical applications.

This review found that 3D bioprinting significantly advances skin tissue engineering by enabling the creation of complex, patient-specific skin structures, though technological and regulatory challenges persist, particularly in areas like scalability and physiological mimicry.

This review found that anti-aging peptides show promise in cosmeceuticals due to their targeted actions to rejuvenate skin, but challenges like peptide stability, penetration, and limited clinical data limit their current effectiveness.

This study found that a cellulose membrane significantly shortened the healing time and reduced the ulcer area in patients with chronic venous leg ulcers compared to a standard antimicrobial dressing.

This research found that the microtubule catastrophe factor KIF18B plays a crucial role in promoting spindle orientation in keratinocytes, linking this process to cell fate decisions during hair follicle morphogenesis.

This study found that αvβ6 integrin inhibits keratinocyte proliferation during wound healing and hair regeneration, suggesting its downregulation may enhance recovery and influence epidermal stem cell behavior.

This research found that Foxc1 transcription factor and COL17A1 are critical in regulating quiescence and hair thinning in hair follicle stem cells, with aging-related DNA damage leading to hair loss.

This study found that melatonin exposure promoted hair follicle fiber growth in Cashmere goat cultures, potentially influencing pathways related to the microvascular system and extracellular matrix.

In this study, dogs with hair cycle disorders, especially those with alopecia X, showed a significant increase in the number of kenogen follicles, suggesting impaired induction of new hair growth phases.

This study explored gene expression in Changthangi goats and found that higher expression of keratin-related genes and specific signaling pathways may play a role in the development of Pashmina fiber.

This study found significant differences in gene expression between newborn and adult skin, with infant skin notably increasing processes related to ECM organization, cell adhesion, and collagen fibril organization.

This study demonstrated that dermal papilla cells are molecularly distinct from fibroblasts and identified many novel molecules, including a new member of the CTGF protein family.

This review examines current and potential approaches to managing chronic wound inflammation through macrophage-targeted strategies using ECM-inspired wound dressings, but it reports no new clinical results.

This study found that γδ T cells play a role in regulating stromal behavior, influencing the composition and vascularity of fibrotic tissues during the foreign body response.

The researchers observed that in cichlid fishes with different dental structures, tooth replacement accelerated more than three times following tooth extraction, alongside distinct changes in gene expression and cellular interactions over one week, providing insights into tooth regeneration mechanisms in vertebrates.

This study observed that while alopecia treatment in patients showed some improvements in quality of life and anxiety scores at six months, these changes were not statistically significant.

This study observed that stem cells from the hair follicle dermis share similarities with bone marrow-derived mesenchymal stem cells and have potential to form neural-like cells under specific conditions.

In this review, retinoids are highlighted as promising agents for promoting scarless skin regeneration by coordinating cellular and molecular processes that suppress fibrosis, enhance re-epithelialization, promote angiogenesis, and enable hair follicle formation, potentially advancing functional skin repair.

This article discusses junctional epidermolysis bullosa caused by COL17 deficiency, noting a lack of experimental therapies and the impact of nonsense mutations, but it reports no new clinical results.

This review discusses the development, lineages, functions, and roles of fibroblasts in fibrosis across four organs, highlighting their capabilities in tissue repair and contributions to fibrotic disorders when aberrantly activated, but it reports no new experimental findings.

Nephronectin helps attach muscle cells to hair follicles.

This review explores recent advancements in understanding how various physiological and psychological factors, such as stress and aging, influence epidermal stem cell populations, highlighting their importance in immune-related skin disorders and potential for clinical applications.
