This review evaluates existing research on Keratin 15 to assess its validity as a marker for epidermal stem cells, reporting no new results.

This pilot study suggests that topical melatonin may protect hair follicle stem cells from paclitaxel-induced damage, potentially preventing chemotherapy-induced alopecia and enhancing the effects of scalp cooling caps.

This study identified and characterized progenitor cells from equine feet that may play a role in the pathogenesis and recovery of laminitis, suggesting potential therapeutic targets for treatment.

This article discusses the mechanisms behind chemotherapy-induced alopecia and the potential for permanent hair loss due to irreversible damage to hair follicle stem cells, but it reports no new clinical findings.

In this pilot study, researchers found that ex vivo treatment with topical melatonin reduced chemotherapy-induced apoptosis and DNA damage in hair follicle stem cells of human scalp cultures, suggesting melatonin's potential as a protective agent against taxane-induced permanent hair loss.

This study found that the phenotype of Hedgehog/Gli-driven skin tumors in mice depends on the cell of origin, tissue context, and level of oncogenic signaling.

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

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 study found that marine-derived collagen peptides slightly promoted hair matrix proliferation and prolonged hair growth phase in human hair follicles ex vivo, suggesting potential benefits for hair loss treatment.

This study suggests that bovine and fish-derived collagen peptides may help maintain or prolong the hair growth phase and balance hair follicle stem cell populations, potentially benefiting aging and hair loss conditions like androgenetic alopecia.

This review discusses various stem cell compartments in adult murine and human epidermis, examining their expressed markers and characterization assays, and reports no new experimental results.

This study demonstrated that hair follicle bulge stem cells can form epidermis in a tissue-engineered skin model, highlighting the significance of K5/K17 filaments in slow-cycling stem cell subsets.

This study found that disrupting Smad4 signaling in young mice led to overactivation of follicle stem cells, causing hyperplasia and depletion of the stem cell niche.

This study found that HPV16 oncogene expression in multipotent epithelial stem cells led to abnormal mobilization, altering their quiescence without affecting other stem cell markers, suggesting a distinct stem cell compartment.

TR3 is mainly found in hair follicle stem cells and may be involved in hair loss.

This study demonstrated that VD3 significantly enhanced the proliferation and differentiation of epidermal stem cells in a murine skin defect model, leading to improved wound healing, potentially through activation of the PI3K signaling pathway.

This study found that targeting mTORC1 with rapamycin effectively inhibited skin tumor promotion in a mouse model, highlighting a potential target for cancer chemoprevention.

This review discusses the role of BMP/Wnt signaling in regulating stem cell homeostasis and activation but reports no new experimental findings.

In this study with mouse follicle stem cells, astraglus polysaccharide increased markers of cell proliferation and gene expression, suggesting a potential mechanism for treating alopecia and promoting hair growth.

This study found that epidermal stem cells are located in rats' hair follicle bulge regions, and the methods used to isolate and culture these cells in vitro are feasible.

This study found that extracellular vesicles from mesenchymal and outer root sheath stem cells may inhibit hair follicle stem cell apoptosis, suggesting potential therapeutic benefits for hair loss treatments.

This study found that apple stem cell extract may selectively influence hair follicle bulge stem cell biology without cytotoxic effects in an ex vivo human hair follicle organ culture.

This study observed that nestin-positive, K15-negative cells in hair follicles may play a crucial role in hair follicle regeneration in patients with alopecia areata.

This study found that mice with a specific loss of DNA methyltransferase 1 showed uneven epidermal thickness, reduced hair regeneration, and progressive alopecia, emphasizing DNA methylation's role in stem cell homeostasis.

This study reports that actively proliferating Lgr5+ stem cells in hair follicles do not appear to drive tumor formation in experimental skin carcinogenesis.

This research details a robust method for isolating hair follicle stem cells and epidermal keratinocytes from mouse hair follicles using fluorescence activated cell-sorting technology.

This study outlines a method to isolate hair follicle stem cells from mouse skin using fluorescence activated cell-sorting for use in research models, but reports no experimental findings.

This study describes a method for isolating stem cells and keratinocytes from mouse hair follicles using FACS technology, facilitating the study of stem cell biology.

This study found that the spermidine analog N1-methylspermidine prolonged hair follicle growth and decreased inflammation and oxidative stress in cultured hair follicles, suggesting potential relevance for treating inflammatory scalp diseases.
