This review highlights similarities in the development of thymus and skin epidermis, reporting no new results; the authors emphasize shared molecular mechanisms despite different embryonic origins.

This study found that Ecklonia cava extract increased skin hydration and decreased redness, suggesting potential benefits for protecting and repairing scalp skin from pollutant-induced damage.

In this study, researchers found that hair follicles and dermal fibroblasts, including dermal papilla cells, supported sustained hair growth in transplanted murine models, with RNA-seq analysis revealing active signaling pathways and gene expression patterns.

In this study, mouse models with EGFR deficiency showed that disrupted hair follicle cycling leads to increased mast cell numbers and inflammation, suggesting EGFR's role in managing hair cycle transitions and preventing folliculitis.

In this study, sequences upstream of the TGM3 gene were found to regulate epithelial-specific gene expression in keratinocytes, suggesting potential applications in gene therapy.

In this study, researchers observed that EGFR deficiency in the epidermis affects gene expression related to cell differentiation and structure, highlighting spatial and temporal roles of EGFR during skin and hair follicle development.

In this study, researchers found that disrupting EGFR signaling in mice led to increased inflammation and hair follicle damage but that inhibiting the JAK-STAT1 pathway could restore hair growth and skin function.

This review outlines the functional anatomy, pathology, and molecular mechanisms of androgenetic alopecia, emphasizing the need for multi-omics approaches to better understand this condition's biology.

In this study, a new cell-tissue technology using a patient's own skin to create a full-thickness skin autograft successfully treated a chronic wound larger than 200 cm², achieving complete functional skin coverage within 12 weeks and maintaining results at a 6-month follow-up.

This study found that adipose‐derived stem cells can restore skin barrier function and inhibit photoaging-related responses in UVB-irradiated mice, suggesting a potential therapeutic role in managing skin photoaging.

This review discusses the role of lncRNA Xist in cell growth regulation and disease development, particularly cancer, and reports no new experimental results.

This study confirmed the localization of CK19 and vimentin in skin cells, with CK19 linked to hair growth and vimentin stabilizing fibroblast structure.

In this study, researchers demonstrated that the expression of the oncogene SmoM2 leads to basal cell carcinoma in the ear epidermis of mice but not in the back skin, with differences in susceptibility linked to the composition of the extracellular matrix.

Caspase-7 has functions in skin and hair that are not related to cell death.

This study found that experimentally induced hypothyroidism in rats is associated with impaired skin structure, but topical application of triiodothyronine (T3) improved these changes to resemble normal skin.

In this study, researchers established a mouse model for single follicular unit transplantation and reported successful integration and piloerection of transplanted hair follicles with surrounding host tissues.

This research describes mouse models to explore Kindlin-1's role in skin disorders, including Kindler syndrome, revealing novel integrin-independent pathways potentially leading to skin tumors.

This study suggests that ELF5 plays a crucial role as a regulator and maintainer of stem/progenitor cell functions, impacting normal skin development and homeostasis.

This review explores hypotheses about hair follicle stem cell function in morphogenesis and cycling, highlights the importance of dermal papilla cells and signaling pathways, and provides no new clinical findings.

This study reported the expression patterns and potential functions of long non-coding RNAs in the hair follicle cycle of yak, with insights into their sequence conservation between yak and cashmere goat.

The Dfl mutation in mice causes poor sebaceous gland function and complete hair loss.

This study documents that trichohyalin acts as a multi-functional cross-bridging protein in the inner root sheath of mouse hair follicles, enhancing mechanical strength by linking keratin filaments to the cell envelope.

This study found that fibronectin is crucial for hair follicle stem cell function and regeneration, with its deletion impairing regeneration but restoration by dermal injection of exogenous fibronectin.

This review discusses various in vitro and in vivo models for studying hair follicle function, noting their potential in developing new treatments for hair disorders but reports no new results.

This study developed HA-gel-dex hydrogels with enhanced ECM-like properties and functionality, showing promise for 3D bioprinting, tissue repair, and as wound dressings due to improved cell interaction, cytocompatibility, antimicrobial synergy, and wound healing in mice compared to traditional ECM bio-inks.

This study found that the loss of a functional hr gene in mice leads to premature and abnormal hair follicle regression, disrupting normal hair cycling and architecture.

Hair follicle stem cells rely on nearby blood vessels for their maintenance and function.

This literature review discusses the challenges and potential strategies for creating fully functional hair follicles capable of active cycling, emphasizing the molecular mechanisms, signaling pathways, and innovative regenerative techniques, such as hair micropatterning and three-dimensional printing, crucial for optimizing hair follicle regeneration.

This study found that ultraviolet radiation negatively affects hair follicle functions in human scalp skin, and caffeine application may provide some protective effects against this damage.

This study suggests that skin-derived precursors from Sox2(+) hair follicle dermal cells have the potential to function as dermal stem cells, supporting hair morphogenesis, dermal maintenance, and wound-healing.
