This article reviews various surgical techniques to improve ocular and cosmetic outcomes in patients with facial paralysis but reports no new clinical results; it emphasizes tailored long-term management strategies.

Sca-1+ cells in newborn mouse skin may become fat cells.

This study found that UV exposure in human skin induces IL-10 production by macrophages, while Langerhans cells are depleted and their IL-12 production is downregulated.

This review discusses the identification and classification of different wrinkle types based on histological features and microanatomy, emphasizing their varying responses to treatments, and reports no new clinical results.

This study describes a protocol for generating hair-bearing skin organoids from human pluripotent stem cells, achieving full complexity resembling fetal skin tissue by day 130 in vitro.

This review highlights the critical role of TGF-β and FGF signaling pathways in the development and regeneration of skin layers, particularly the dermis, and discusses their significance in advancing future clinical applications in dermatology.

This study found significant differences in scalp microbiome composition and volatile organic metabolites between individuals with alopecia areata and healthy controls, suggesting potential microbiome-related therapeutic interventions for hair growth disorders.

This ex vivo study reported that melatonin significantly improved certain aging biomarkers in aged human skin, including reduced mTORC1 activity, increased fibrillin-1, and enhanced collagen and elastic fiber organization, though other key biomarkers remained unchanged.

This study found no qualitative skin differences during development between mutant hairless USP mice and BALB/c mice, except for enlarged cysts in the hairless strain.

This study found that in skin blister healing, hair follicle development is compromised as stem cells repair wounds at the expense of morphogenesis gene expression.

This article outlines a protocol for scanning electron microscopy of murine skin and primary keratinocyte monolayers, providing a guide for sample preparation and examination.

This review discusses various methods for processing and separating human skin samples for research purposes, evaluating factors like processing time and cell viability, but reports no new experimental findings.

This article reviews the functions and locations of skin stem cells and their role in regeneration and differentiation, relating age-associated skin changes to decreased stem cell functionality; it reports no new experimental findings.

In this study, maternal exposure to constant light significantly altered the neonatal skin structure in rabbits, associated with reduced maternal melatonin levels.

This review discusses the use of human-to-mouse xenografting to study human skin processes in vivo, highlighting its importance for understanding skin regeneration and pathology while identifying knowledge gaps and challenges in applying these findings to human skin.

This study found that differentiated cells of the corneal epithelium can be converted to hair and interfollicular epidermis through a multistep process involving dermal developmental signals.

This study found that dermis micrografting improved hair growth and density in patients with androgenetic alopecia over 4, 6, and 12 months, suggesting it could be a novel treatment option.

This study suggests that GATA6 is a key regulator of the upper pilo-sebaceous unit homeostasis and differentiation in human skin.

This review explores fibroblast heterogeneity in the mammalian dermis and suggests potential therapeutic applications by targeting fibroblast subtypes, but reports no new experimental results.

This article outlines a targeted approach for optimal upper facial rejuvenation in male patients but presents no new clinical findings.

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.

This study found that transgenic mice overexpressing HGF/SF are more susceptible to UVA-induced melanoma, with melanin in the papillary dermis interacting with UVA to induce melanoma.

This review examines the diversity and role of stem cells in the adult dermis, noting a lack of precise understanding about their hierarchy and relationship to dermal fibroblast subpopulations, and reports no new results.

This review discusses the cutaneous application of bimatoprost ophthalmic solution 0.03% for enhancing upper eyelash growth and suggests it is both safe and effective; no new clinical results are reported.

This study suggests that the postnatal loss of hair follicle formation in wounds may be due to elevated Wnt/β-catenin activation in the dermis, affecting fibroblast function in mice.

This study found that the HPCH-based formulation P-08–016 may facilitate finasteride deposition in the dermis, potentially offering an alternative to systemic therapy by minimizing systemic absorption.

This study found that activating Wnt/beta-catenin signaling in hair follicles is sufficient to induce adipocyte generation in the dermis, affecting both hair follicle stem cell activation and adipocyte differentiation.

This report documents the second known case of Castleman's disease in the lacrimal gland, diagnosed in an 84-year-old woman through histological examination after excising a left upper lid mass.

In this study, full-thickness wounding on Lanyu pigs led to scar formation and disrupted cell markers, while partial-thickness wounding allowed limited regeneration of rete ridges and papillary dermis.

This study identified a distinct CD49fhigh mesenchymal stem cell subpopulation in the dermis that supports hair follicle development and maintenance via Notch signaling activation.
