This review discusses various approaches to treating alopecia, including drug therapy and hair transplantation, but reports no new research findings; the authors highlight the need for novel techniques like cell culturing.

Stem cells compete for space using cell adhesion, and mutations can affect their competitive success, with implications for tissue health and disease.

This study found that micro-niches within hair follicles create heterogeneity among stem cells and transit-amplifying cells, leading to specialized progenitors that control tissue morphogenesis and regeneration.

This study found that Lgr5 and Lgr6 stem cells both activated wound-healing genes, but only Lgr5 stem cells changed their identity to contribute to new skin formation during wound repair.

This review outlines recent advances in using stem cells for skin repair and regeneration, suggesting potential for complete skin and appendage regeneration after severe burns, but presents no new clinical findings.

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 canine bulge-derived keratinocytes are highly proliferative and can reconstitute pilosebaceous structures, indicating their potential utility in studying human stem cell biology and hair disorders.

This review examines the potential mechanisms by which stem cell-derived cell-free therapy may prevent skin aging, highlighting various molecular targets and pathways involved in regeneration, oxidative stress regulation, ECM preservation, cell activity modulation, and inflammation.

This chapter reviews the properties and applications of epidermal stem cells in skin tissue engineering and transplantation but reports no new experimental results.

This article reviews how stem cell exhaustion contributes to aging, emphasizing the balance between proliferation and quiescence as crucial for long-term stem cell maintenance, but it reports no new results.

This review summarizes the mechanisms of mesenchymal stem cell-mediated wound healing and highlights engineering strategies that enhance therapeutic outcomes, but it reports no new clinical results.

This review explores the potential of cell-mediated drug delivery systems in dermatology, highlighting their ability to target inflamed or diseased skin while discussing applications in diseases like atopic dermatitis and melanoma, along with challenges such as immunogenicity and manufacturing.

This review discusses mesenchymal stem cells' role in tissue regeneration and skin anti-aging, highlighting their migration to damaged sites and secretome effects, but reports no new clinical results.

This review highlights the potential of stem cell-based therapies, including hair follicle, mesenchymal, and induced pluripotent stem cells, as promising future treatments for alopecia, noting their regenerative and immunomodulatory capabilities as well as ongoing studies evaluating their effectiveness in overcoming current therapy limitations.

This study found that exosomes derived from human umbilical cord mesenchymal stem cells helped preserve melanocyte function and mitigate stress-induced hair depigmentation in mice by activating the Nrf2-ARE antioxidant pathway under acute neurogenic oxidative stress.

This review outlines the potential of mesenchymal stem cells and their derivatives as emerging therapies for atopic dermatitis, but reports no new clinical results; the authors highlight the need for further investigation.

This paper reviews the role of ATP-dependent chromatin remodeling complexes in epidermal homeostasis, hair regeneration, and skin repair, noting contributions to 3D-genomic organization and suppression of UV-induced hyper-proliferation, without presenting new results.

This review suggests that stem cells might be a promising addition or alternative to standard treatments for androgenic alopecia, but larger studies are needed to confirm these findings.

This review found that image-guided techniques in regenerative aesthetic procedures may enhance accuracy and patient outcomes compared to traditional methods, but more high-quality randomized trials are needed to establish standardized protocols.
