This study found that using a nonablative 1927 nm wavelength laser followed by hydroquinone cream is safe and effective for treating postinflammatory hyperpigmentation in patients with dark skin types.

This study developed polymer nanoparticles with and without chitosan coating to deliver dutasteride to hair follicles for treating androgenic alopecia. Both nanoparticle types showed controlled drug release and enhanced follicle targeting, especially with mechanical stimulus, supporting their potential as effective topical carriers in skin layers.

This study found that keratin 14 may serve as an autoantigen in autoimmune skin diseases, indicated by its altered expression in affected skin and reactivity of patient sera.

This study found that K15 is a useful marker for investigating the role of stem cells in canine hair follicle tumours, while nestin is not optimal.

This study demonstrated that mice lacking skin-specific RXRalpha expression developed hair follicle degeneration and alopecia, indicating the importance of RXRalpha/VDR heterodimers in maintaining hair follicle homeostasis.

This study found that YAP1 localization and expression patterns in human skin xenografts resembled pathological conditions, suggesting that YAP1 may be a potential target for treating skin pathologies.

The new skin organoid system effectively mimics human skin for studying its functions, injuries, and diseases.

This study found that blocking apoptosis during the catagen phase in mice disrupts hair follicle stem cell niche architecture, delaying subsequent hair regeneration cycles.

In this study, high-resolution ultrasound imaging revealed that DHT administration in male C57BL/6 mice leads to increased epidermal and dermal thicknesses and decreased skin elasticity, simulating structural changes associated with Androgenetic Alopecia.

Human hair follicles have a unique cell distribution and differentiation pattern during growth.

This study reports that the fatty acid composition in cell membranes of stratified squamous epithelium varies with keratinization patterns, showing a partial essential fatty acid-deficient state in cultured keratinocytes.

Canine skin has two main layers: the epidermis and dermis, with a supportive subcutis layer.

This study successfully cultured human fetal hair follicle-derived melanocytes, which showed high proliferative capabilities and unique morphological characteristics compared to adult-derived cells, potentially advancing hair disease research.

This review explores how adult skin epithelia preserve stem cell populations for hair follicle regeneration and wound healing, but reports no new experimental results.

This article reviews how various chemical agents affect human hair and skin, suggesting the need for more research on their pharmacologic and dermatologic effects; it does not report new experimental results.

This study found that MK6a-deficient mice showed delayed reepithelialization after superficial wounding but not after full-thickness skin wounds, suggesting MK6a plays a role in activating follicular keratinocytes post-wounding.

Double trichophytic closure effectively repairs thin scalp scars, reducing financial burden.

This study reports the successful differentiation of mouse induced pluripotent stem cells into keratinocytes that can regenerate skin and its structures in an in vivo environment.

This chapter reviews skin components, wound healing mechanisms, and the potential of biomaterials to enhance skin repair and regeneration, without offering new experimental results.

This study found that incorporating human adipose subcutaneous tissue in 3D organotypic skin cultures mimicking hypertrophic scar conditions improved epidermal homeostasis, formed a basement membrane similar to native skin, and reduced myofibroblast presence, indicating an anti-fibrotic effect.

This article reviews the anatomy and pathology of skin and hair to aid in diagnosing skin diseases and discusses potential therapies, without reporting new clinical results.

This review explores recent insights into the diverse cell populations involved in skin development, homeostasis, wound healing, and cancer progression but reports no new results.

This article discusses the interactions between keratinocytes and melanocytes in maintaining epidermal and hair follicle homeostasis, without reporting new experimental results.

This review discusses current concepts on the role of retinoids in keratinization and does not report new clinical results; the authors emphasize the complexity of retinoid effects on skin.

The skin is essential for protection, temperature control, and immune defense.

This study identified and characterized a gene called 4C32, which is expressed in the periderm of embryonic mouse skin and has a structure similar to keratin-associated proteins.

ZPK helps skin cells mature and may affect skin health.

In this study, trichocytes were shown to have potential for alternative differentiation, with mesenchymal cell influences playing a critical role in determining this process.

The document concludes that hair biology is complex and there are still unanswered questions about hair loss and follicle changes.

This review discusses the dynamic changes in chromatin organization and nuclear morphology during cellular processes like differentiation and disease, highlighting recent advances in understanding these epigenetic mechanisms without presenting new experimental findings.
