This study developed a tissue-engineered model of innervated skin, allowing for examination of how epidermis and capillaries affect nerve growth and offering a tool for further research on skin-related processes.

This study found that in mice, including middle-aged and aged specimens, creating a wound without dermal defects and using adhesive materials to separate the epidermis from the dermis induced new hair follicle formation, suggesting potential applications for treating hair loss.

This study used multi-scale hybrid models to explore how signaling factors affect skin wound healing and embryo development, suggesting that different levels of fibrin clot density influence scar formation.

This study found that a serum-free DMEM-F12 medium with 45% oxygen best supports in vitro development and differentiation of human fetal skin, closely mimicking the in vivo state.

This study suggests that exogenous retinoic acid can alter the morphogenesis pathway of developing skin appendages when applied during the placodal stage, leading to changes like feather formation in atypical regions of chick embryos.

This study showed that coexpression of TG2 and Gbx1 in the epidermis is necessary for esophagus-like mucosal transdifferentiation, with TGF-beta2 in the dermis essential for the process through epithelial-mesenchymal interaction.

This study found that co-transplanting mouse epidermis and dermis cells induced new hair follicle formation, while isolated or cultured dermis cells contributed to follicle-related structures differently.

Hair growth is influenced by interactions between skin layers, growth factors, and hormones, but the exact mechanisms are not fully understood.

In this study, researchers observed that epidermal damage may increase susceptibility to Bacillus anthracis infection, allowing it access through hair follicles and the denuded dermis in mice.

This study reports that follicular cells isolated from murine skin can regenerate hair follicles after being injected into nude mouse skin, with the regeneration process relying on cell interactions, recipient sites, and cell numbers.

This study found that CTIP2 is highly expressed in mouse skin during embryogenesis and adulthood, suggesting it may play a role in skin development and homeostasis.

Retinoic acid causes gland formation instead of hair in mouse skin by altering epidermal and dermal interactions.

This study suggests that the phenotype of melasma in women is influenced by structural and cellular changes across the epidermal-melanin unit, not just melanocyte hypertrophy, highlighting potential roles for dermal damage repair and fibroblast senescence.

This study suggests that age-related changes in skin elasticity reduce its stability against wrinkling, and anti-aging strategies should focus on addressing elastic mismatches between skin layers.

This study identified a group of dermal fibroblasts near hair follicle stem cells in mice that facilitate hair regeneration by creating a biomechanically compliant extracellular matrix, enhancing stem cell activation and promoting a positive feedback loop for tissue regeneration.

This study found that donor age and culture medium significantly impact the quality of human full-thickness skin models, with implications for their use as animal model alternatives in research.

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.

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

This article discusses the role of clinical observation and microscopic correlation in American dermatology training and reports no new clinical results.

This study introduced the concept of spatiotemporal clocks to understand how different phases of mammalian wound healing are coordinated, with a focus on the spatial domains and oscillatory molecular signals involved, while highlighting the potential for regenerative therapeutic strategies.

This review discusses the challenges and contradictions in understanding nanoparticle penetration and toxicity in human skin, emphasizing the need for standardized testing and further research on particles smaller than 10 nm.

In this study, retinoic acid treatments induced glandular and feather formation in embryos by altering positional values and activating specific retinoic acid nuclear receptor gene expression.

This article explores the use of monoclonal antibodies to study the presence and distribution patterns of melanocytes in developing human skin, but reports no new clinical results.

This study found that polyamidoamine dendrimers can permeate skin's current conducting pores and alter the magnitude and direction of electroosmotic flow, affecting drug flux during iontophoresis.

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.

In this mouse study, researchers found that dermal Wnt signaling/β-catenin activity is essential for fibroblast proliferation and initiating hair follicle formation by interacting with epidermal Wnt ligands.

This study found that engineered reconstituted skin can form morphogenetic units that promote tissue patterning and hair regeneration, with certain signaling pathways restoring this ability in adult and fetal cells.

This study found that in stretch-mediated tissue expansion, fibroblasts adopt an embryonic-like, low-collagen state that enhances epidermal stem cell renewal, supporting coordinated skin expansion crucial for reconstructive surgeries.

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.

In this study, researchers discussed how specific protein interactions in reptile skin allow for the development of protective structures like scales and scutes, which facilitated reptiles' adaptation to terrestrial environments.
