This study found that an ethanolic extract from the microalga Tetrathelmis tetrathele exhibited anti-inflammatory effects, promoted the proliferation of certain skin and hair cells, and inhibited 5α-reductase activity, suggesting its potential as a therapeutic agent for preventing alopecia and enhancing scalp health.

This study found that in mice, chronic stress elevates corticosterone levels, which suppresses hair growth by keeping hair follicles in a prolonged resting phase.

This review examines the potential of stem cells and their derived products, such as exosomes and conditioned media, in improving burn wound healing but presents no new clinical data.

This study highlights that stress-induced activation of the HPA axis in human hair follicles can lead to hair growth arrest, but variability in follicle response complicates potential therapeutic approaches.

This study found that treating aged mice with the Cdc42 inhibitor CASIN restored hair follicle stem cell functionality and improved hair regeneration by inducing anagen onset and increasing anagen skin areas.

In this study, transplantation of rat hair follicle stem cells was associated with reduced infarct volume and enhanced neurological recovery after ischaemic stroke, suggesting therapeutic potential for further clinical development.

This study found that aPKCλ, but not aPKCζ, plays a critical role in maintaining hair follicle stem cell populations and promoting wound healing in the epidermis.

This study found that hair follicle stem cells, when transplanted in a rat model of ischaemic stroke, migrated to affected areas, expressed neuron-specific markers, and reduced infarct volume, suggesting potential therapeutic benefits.

In this study, hair follicle stem cells were reported to accelerate burn wound healing and increase tissue tensile strength in rats.

This study found that Ecklonia cava extract increased skin hydration and decreased redness, suggesting potential benefits for protecting and repairing scalp skin from pollutant-induced damage.

This study found that the PPARγ modulator NAC-GED-0507-Levo may protect hair follicles from chemotherapy-induced damage, potentially offering a strategy to address irreversible hair loss in cancer patients.

This study reports that in mice, retinoic acid mediates communication between hair follicle and melanocyte stem cells by influencing differentiation in their shared niche during hair regeneration.

In this study, the researchers observed that Biofield Energy Healing Treatment significantly increased hair follicle cell proliferation in human dermal papilla culture, suggesting potential as a hair growth enhancer.

This study found that the PPAR-γ modulator AGED can reverse epithelial-mesenchymal transition in hair follicles affected by lichen planopilaris ex vivo, suggesting potential for treating scarring alopecias.

This study found that in laboratory settings, dermal papilla cells cultured as spheroids showed significantly higher hair inductive potential and angiogenic factor expression compared to monolayer cultures.

This study identified a specific subset of macrophages as a key source of oncostatin M, maintaining hair follicle stem cell quiescence during the resting phase in mice, suggesting a potential target for treating hair disorders.

In this study using a transgenic mouse model, Id2 overexpression in hair follicle stem cells prolonged quiescence by affecting gene expression, partly independent from BMP signaling.

This study found that IL-1α and IL-7 secreted from keratinocytes in a genetically engineered mouse model can stimulate the expansion of γδT-cells, aiding in the proliferation of epidermal stem cells for wound healing.

This study found that N-acetyl-GED may protect and partially rescue human hair follicles from experimentally-induced epithelial-mesenchymal transition ex vivo, suggesting its potential in treating scarring alopecias like lichen planopilaris.

This study found that conditioned media from SHED stem cells cultured in STK2 media significantly stimulated hair growth in mice more effectively than media from HFSCs.

This study found that the enzyme Acer1 plays a crucial role in skin health and tumor prevention by regulating ceramide metabolism in mice.

This study found that interleukin-1α and interleukin-7 secreted by keratinocytes enhance the proliferation of γδT-cells and epidermal stem cells, revealing mechanisms of stem cell activation during wound healing in mice.

Hox genes control hair follicle stem cell regeneration in different body regions.

In this study, researchers demonstrated that the Id2 gene acts as a direct target and effector of BMP signaling, playing a key role in maintaining quiescence in hair follicle stem cells in vivo.

This study found that knocking out STAT5 expression in specific mouse hair follicles after tamoxifen treatment initiated uniform hair growth, highlighting STAT5's role in regulating the hair growth cycle.

This study found that hair follicle stem cells can proliferate and differentiate into keratinocytes on chitosan skin-engineered templates, suggesting potential applications in regenerative medicine.

This study confirmed porcine PRP's commercial viability as a fetal bovine serum replacement, showing higher growth factor levels and stability, without increasing human follicle dermal papilla cell proliferation compared to FBS.

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.

This study suggests that 70% ethanol extracts from certain medicinal plants may promote hair growth and be useful for developing hair care products.

This review discusses the roles and characteristics of skin stem cells, their niches, and signaling pathways in skin maintenance, aging, and cancer, highlighting their potential in therapeutic applications but presenting no new clinical findings.
