In this study, Stat3 activation in transgenic mice led to a decrease in stem cells in the hair follicle bulge, suggesting its crucial role in epidermal growth and stem cell maintenance.

Linalool in fragrances may harm hair follicles and contribute to hair loss.

This study revealed that Vav2 and Vav3 play roles in regulating hair follicle bulge stem cells in normal conditions and cancer stem cell activation and remodeling in mice.

This study found that androgens inhibit hair follicle stem cell differentiation by disrupting the Wnt signalling pathway in dermal papilla cells, but Wnt activation can restore differentiation.

In this study, hair follicle stem cell-derived exosomes enriched with miR-181a-5p accelerated hair regrowth and the transition from telogen to anagen in mice, with up to 90% hair coverage observed, suggesting enhanced activation of the Wnt/β-catenin pathway compared to controls.

This study found that the loss of ASLNC168501 accelerates hair follicle stem cell dysfunction in androgenetic alopecia through activation of the AR/miR-128-3p/IGF-1 pathway, suggesting that restoring ASLNC168501 could be a promising therapeutic strategy for hair regeneration.

This review highlights that chronic inflammation leads to ongoing activation of stem cells, causing DNA damage accumulation, which can promote cancer development and metastasis.

This study found that preconditioning human hair follicle-derived stem cells with valproic acid enhanced their survival and migration in ischemic-like conditions by activating autophagy and inhibiting the AKT/mTOR pathway, suggesting this approach could improve stem cell therapies for ischemic stroke.

In this study, thymosin beta4 was found to stimulate hair growth in normal rats and mice by affecting key processes in the hair follicle cycle, such as stem cell migration and extracellular matrix remodeling.

This review concluded that chronic inflammation can lead to persistent activation of stem cells, accumulating DNA damage and promoting cancer development and metastasis from stem cell origins.

This review concludes that chronic inflammation can lead to persistent activation of stem cells, accumulating DNA damage that promotes cancer development and metastasis, by affecting normal stem cells, cancer stem cells, and cancer cells.

This literature review reports that chronic inflammation can lead to persistent activation of stem cells, accumulating DNA damage, and eventually promoting cancer development and metastasis even before stem cells become cancerous.

This review concludes that chronic inflammation can lead to persistent activation of stem cells, which may accumulate DNA damage and ultimately promote cancer, while also facilitating cancer metastasis.

This study found that FPR2 knockout mice experienced excessive hair loss and abnormal hair follicle structures, suggesting FPR2's protective role in hair regeneration through stem cell activity regulation.

This study found that exosomes derived from human amniotic mesenchymal stem cells enhanced stem cell proliferation and structural restoration in irradiated salivary glands of rats, with significant improvements observed by day 7, suggesting activation of the Wnt signaling pathway.

This study suggests that pilose antler extracts promote hair regrowth in androgenetic alopecia mice by activating the AKT and Wnt pathways, enhancing hair follicle stem cell proliferation.

In this study, preconditioning hair follicle-derived stem cells with valproic acid and/or rapamycin was shown to protect against damage caused by oxygen glucose and serum deprivation, potentially enhancing stem cell therapy efficacy for ischemic stroke by improving cell adaptation to oxidative stress.

This research found that exosome-derived long non-coding RNA AC010789.1, modified by FTO and hnRNPA2B1, enhanced human hair follicle stem cell proliferation against androgenic alopecia through the activation of S100A8/Wnt/β-catenin signaling pathways.

This article explores how extrafollicular environments and stem cell configurations influence hair and feather regeneration but provides no new experimental results.

In this mouse study, NF-κB was shown to play a role in hair follicle cycling and morphogenesis, with specific activity patterns differing by hair type and involving noncanonical signaling for zigzag hair bending.

This study found that in Pomeranians with Alopecia X, key genes in the Wnt and Shh signaling pathways and stem cell markers are downregulated, which may explain the absence of anagen hair follicles.

Platelet Rich Plasma (PRP) shows promise for tissue repair and immune response, but more research is needed to fully understand it and optimize its use.

This review summarizes recent therapeutic advancements in treating various forms of alopecia, including new applications of oral minoxidil, dutasteride, finasteride, Janus kinase inhibitors, and novel hair transplant techniques, without presenting original research results.

This study suggests that age-related regenerative decline in hair follicles may be due to an imbalance of signals affecting stem cell activation, with follistatin potentially promoting renewal.

This study found that topical application of partial proteasomal inhibitors accelerates hair growth by stabilizing β-catenin and disrupting the hair cycle's normal balance of activation and quiescence.

This review discusses the fundamental features of hair follicle biology and its clinical importance, but it reports no new clinical results.

This review highlights advancements in nanotechnology-based treatments for androgenetic alopecia, noting that these strategies could improve targeting and modulation of hair follicle environments compared to traditional therapies like minoxidil and finasteride, but also emphasizes challenges around safety, manufacturing, and regulation.

This paper reviews the emerging role of FGF-7 signaling in hair regeneration, highlighting its potential as a target for new therapies despite limited clinical trial data.

This study found that platelet-rich plasma therapy significantly improved hair density, diameter, and reduced inflammation in androgenetic alopecia patients compared to placebo, though individual responses varied.

This case study observed that high-intensity focused ultrasound treatment significantly improved hair density and reduced hair loss in a female patient with androgenetic alopecia, with no adverse events reported.
