This review discusses strategies for regenerating cutaneous nerve function in burn patients and highlights the potential role of autologous skin-derived adult stem cells in improving sensory recovery, but reports no new experimental findings.

This review highlights various methods of stem cell communication that reflect the unique organization and function of different tissues and reports no new results.

This study found that activin affects both stromal cells and keratinocytes in skin morphogenesis and repair, with dose-dependent effects on keratinocytes demonstrated through transgenic mouse models.

This review outlines various clinical methods for assessing ageing skin and discusses their application in supporting the efficacy claims of anti-ageing treatments, but it reports no new clinical results.

This review explores how androgens and growth hormone influence the development of terminal hairs and sebaceous glands, attributing variability in hirsutism and acne to differing genetic sensitivities to androgens, but reports no new experimental data.

This review discusses recent advances in hair follicle biology, regeneration, and tissue engineering, highlighting emerging therapeutic opportunities, and reports no new experimental results.

This study observed that human hair follicles were able to regenerate fiber-forming structures after the bulb was amputated and transplanted onto athymic mice, suggesting a general regenerative capacity.

This study found that hair thickness and density increased after treatment with human follicle mesenchymal stem cells and platelet rich plasma, associated with enhanced Wnt signaling and platelet derived growth factors.

Hair growth can be induced by certain cells found at the base of hair follicles, and these cells may also influence hair development and regeneration.

This review discusses how macro-environmental factors such as intradermal adipose tissue and sex hormones influence hair and feather stem cell niches, suggesting environmental targets for regenerative medicine, but reports no new clinical results.

This review discusses the role of mechanical forces in skin homeostasis and disease development, including their impact on conditions like keloids, androgenetic alopecia, and acral melanoma, and reports no clinical results; the authors propose modifying these forces as a potential therapeutic strategy.

This review discusses the unique features of dermal white adipose tissue, its interaction with hair follicles, and its role in skin physiology, reporting no new experimental findings.

This study suggests that a novel micropatterned dermal–epidermal matrix (μDERM) enhances keratinocyte function and epidermal morphology, offering potential improvements in skin substitute design for wound healing applications.

This study found that keratin 6hf, a type II keratin, is expressed in specific regions of mouse and human hair and suggests potential interactions with keratin 17, impacting hair development and associated disorders.

This review discusses the development and application of multiphoton microscopy in dermatology, highlighting its advantages and potential future research directions without reporting new clinical results.

This study found that nanostructured lipid carriers with clobetasol propionate significantly enhance follicular drug delivery compared to commercial cream, and manual massage further doubles follicular retention.

This study found that over-expressing Spry4 and Fgf10 modulates feather stem cells to alter feather morphologies in distinct ways, affecting barb branch formation and tissue structure.

The study found that bioengineered hair follicles work when using cells from the same species but have issues when combining human and mouse cells.

This review explores the role of Eph receptors and ephrins in skin cell processes, discussing their potential for therapeutic targeting in dermatological disorders, but it presents no new research findings.

This study suggests that mesenchymal stem cell-induced dermal papilla-like tissues can generate new hair follicles in mice, indicating potential for developing hair cell therapy using stem cells.

This study visualized mitochondrial metabolism in cultured bovine hair follicles and plucked human hairs, finding that ROS and mitochondrial polarization correlate in specific hair follicle regions, particularly near keratin deposition sites.

This study found that hydroxysafflor yellow A-rich Carthamus tinctorius extract promoted hair growth and gene expression linked to hair proliferation in both cell cultures and mouse models.

Keratin patterns in hair follicles help understand hair growth and potential hair and nail disorders.

This study found that dermal sheath stem cell characteristics are lost with aging in humans, affecting skin rejuvenation and structure, and identified specific proteins like Activin A influencing keratinocyte and fibroblast activity.

This study found that extracellular vesicles from stimulated human dermal fibroblasts enhanced hair follicle growth ex vivo by activating dermal papilla cells and involving the Norrin and β-catenin pathways.

This study suggests that the absence of alpha5(IV)/alpha6(IV) chains in certain subepidermal basement membrane spots may relate to interactions with melanocytes in human skin.

This study found that upper wound fibroblasts are crucial for hair follicle regeneration during wound healing and suggests that these cells, along with papillary fibroblasts, migrate within the wound.
