This paper reviews signaling influences and niches of epidermal stem cells and compares various types, but does not present new experimental findings.

This study found that cutaneous stem cells in the basal layer of fetal human skin contribute to the development of the epidermis and hair follicles, with specific marker expressions during different stages of skin development.

This chapter describes procedures for isolating and purifying murine epithelial progenitors and assessing their ex vivo propagation capacity, but presents no new experimental results.

This review discusses the evolving understanding of epithelial stem cells, noting how new models challenge old assumptions and suggesting multiple stem cell populations contribute differently to skin and hair follicle regeneration.

This review examines current treatments and the potential role of stem cells in cutaneous wound healing, but it presents no new clinical results and calls for more research on mechanisms.

This study found that in the absence of hair follicles, cutaneous wounds in mice showed delayed reepithelialization but eventually achieved normal wound closure after expanding the activated epidermis region.

In this study, human bone marrow mesenchymal stem cell-derived exosomes significantly accelerated cutaneous wound healing in rats by modulating the TGF-β/Smad signaling pathway.

This study found that the vitamin D receptor is essential for the self-renewal, migration, and differentiation of epidermal stem cells during skin wound healing in mice.

This article discusses stem cell-based therapies for wound healing and highlights their potential for tissue repair and regeneration, without presenting new clinical results.

This study found that KLF4 expression in mouse hair follicle stem cells is important for effective cutaneous wound healing, with its knockdown leading to reduced stem cell populations and delayed healing.

This study reported that black hairy tongue can occur after allogeneic stem cell transplantation and may indicate cutaneous graft-versus-host disease, highlighting the need for histopathologic evaluation.

This study demonstrates that the newly developed portable reflectance confocal microscope (PRCM) offers real-time, noninvasive monitoring of wound healing processes by visualizing skin morphology in both mice and humans.

This study found that implanting HAP stem cells in a mouse model accelerated wound closure and reduced scar formation, suggesting potential for scar-free wound healing.

This study found that exosomes derived from human bone marrow mesenchymal stem cells significantly promote cutaneous wound healing in rats by modulating the TGF-β/Smad signaling pathway.

This study found that activation of the transcription factor Nrf2 in keratinocytes promotes wound healing in mice by expanding hair follicle stem cells, independent of changes in keratinocyte proliferation or migration.

This study found that in obese mice, local antimicrobial activity is reduced due to a loss of adipogenic stem cells and an increase in mature adipocytes, leading to higher susceptibility to skin infections.

This study found that patients with unresectable melanoma treated with AZD6244 experienced skin reactions, including depigmentation and papulopustular rashes, in patterns similar to those caused by EGFR inhibitors.

In this study, intravenous injection of exosomes derived from mesenchymal stromal cells accelerated wound healing and improved skin tissue regeneration in adult male rats.

This study suggests that exosomal miRNAs from human amniotic fluid stem cells may inhibit myofibroblast differentiation and reduce fibrotic scarring in wound healing.

This study found that the absence of Ctip2 in epidermal keratinocytes led to impaired wound healing in mice, affecting cell migration, proliferation, and hair follicle stem cell maintenance.

This study reports that miR-22 promotes cancer progression and metastasis by maintaining Wnt/β-catenin signaling and cancer stem cell function.

This study found that a newly developed injectable hydrogel combined with human umbilical cord-mesenchymal stem cells significantly accelerated wound healing and reduced inflammation in full-thickness cutaneous wounds.

This study found that topical application of nano-Zinc oxide in newborn mice led to the accumulation of nanoparticles within hair follicles, inducing apoptosis of hair follicle stem cells and potentially disrupting skin homeostasis.

This study suggests that damage to stem cells in the bulge region of hair follicles may contribute to scarring in chronic cutaneous lupus erythematosus.

This review discusses advancements in stem cell therapy for cutaneous radiation syndrome, highlighting the potential of various stem cell sources to improve wound healing and reduce symptoms, but reports no new clinical results.

In this study, umbilical cord mesenchymal stem cell-derived apoptotic extracellular vesicles were found to improve wound healing in type 2 diabetic mice by inhibiting macrophage pyroptosis and reducing oxidative stress levels.

This review discusses how dental pulp stem cells and their derivatives may accelerate skin wound healing by modulating inflammation, promoting angiogenesis, optimizing extracellular matrix structure, and enhancing tissue formation, with implications for translating these findings into therapies for skin and mucosal repair.

This study found that bone marrow-derived epithelial cells were abundantly recruited to some skin tumors in mice, indicating a systemic contribution to cutaneous neoplasms.

In this study, researchers found that bone marrow-derived epithelial cells significantly contribute to the development of cutaneous tumors and dysplastic ulcers in mice, indicating a potential systemic role in skin cancer development.

This study found that topically applied nano-Zinc oxide accumulated in hair follicles and induced apoptosis in hair follicle stem cells, indicating a potential risk to skin homeostasis.
