In this study, CD4+ non-haematopoietic, skin-resident stem cell-like populations were identified in both murine and human epidermis, suggesting they may serve as potential basal cell carcinoma precursors.

This study found that Ift20 is essential for hair follicle stem cell identity and hair regrowth, and it regulates keratinocyte migration during wound healing through focal adhesion integrin recycling, independently of ciliogenesis.

This study reports that tofacitinib, a JAK inhibitor, may stabilize hair loss in patients with classic lichen planopilaris and frontal fibrosing alopecia, though hair regrowth was not robust.

This review discusses recent advances in understanding alopecia areata's disease mechanisms and highlights JAK molecules as promising therapeutic targets, but reports no new clinical results; controlled trials are needed.

This study concluded that human epidermal stem cells cultured in MEM-α and EpiLife media with growth factors show high proliferation potential and plasticity, suggesting potential use in skin regenerative medicine.

In this study, transplantation of hair follicle stem cells and nerve growth factor-modified stem cells significantly reduced amyloid deposition and tau hyperphosphorylation in an Alzheimer's disease rat model, suggesting potential as a treatment option.

This review discusses current knowledge of keratinocyte stem cell dynamics, including their regenerative roles and potential applications beyond wound healing, but presents no new clinical findings.

This literature review discusses the challenges and potential strategies for creating fully functional hair follicles capable of active cycling, emphasizing the molecular mechanisms, signaling pathways, and innovative regenerative techniques, such as hair micropatterning and three-dimensional printing, crucial for optimizing hair follicle regeneration.

The study introduced an advanced skin model, ImmuSkin-MT, which effectively distinguished between different strengths of skin sensitizers by mimicking the interaction of immune cells in skin tissue.

In this study, researchers used 3D bioprinting with skin stem cells and specific hydrogels to create artificial skin that successfully promoted complete wound healing and the regeneration of skin structures, including hair follicles and blood vessels, in mice.

In this study, Erianin was found to significantly suppress alopecia areata in a mouse model by inhibiting effector T cell function, reversing systemic symptoms, and promoting hair growth.

This study suggests that using cell-free dexamethasone-primed stem cell media may offer a promising alternative treatment for systemic lupus erythematosus, showing immunomodulatory benefits and therapeutic efficacy in reducing various complications.

This study demonstrated that in mice, the absence of Jagged-1 expression in skin-resident regulatory T cells significantly delays wound healing by reducing the accumulation of neutrophils, highlighting the role of Jagged-1 in coordinating immune cell recruitment during injury.

In this mini-review, recent insights suggest a possible role of type-2-related immunity in diseases like alopecia areata, vitiligo, and localized scleroderma, though whether this immune response benefits or worsens these conditions remains unclear.

In a keratinocyte-specific knockout mouse model, this study found that deleting GRK2 disrupted hair follicle homeostasis, causing cyst-like structures, abnormal growth patterns, and eventual hair loss, suggesting potential links to immune-mediated alopecias.

This study found that in mice, oral administration of Lactilactobacillus curvatus LB-P9 accelerated hair regrowth and increased hair thickness, hair follicle numbers, and dermal thickness, likely by boosting hair growth factor production and dermal papilla proliferation.

This study found that a catalytically active version of Vav2 significantly altered gene expression patterns in hair follicle stem cells in mice, with these changes varying over the animals' lifespans.

T cells and bacteria in the gut and skin help maintain health and protect against disease.

This study found that inducing miR-205 reduces actin contractility and stiffness in hair follicle stem cells and progenitors, stimulating hair regeneration in both young and old mice.

3D-oxy exosomes may significantly boost hair growth, offering new treatment options for hair loss.

This study provides evidence that innate lymphoid cells-type 1 can induce alopecia areata in human hair follicles, challenging the view that it is solely a CD8+ T cell-driven autoimmune disease.

This study found that type 2 immunity, especially involving ILC2 cells, helps maintain skin homeostasis by regulating the proliferation and community stability of hair follicle epithelial cells in the presence of Demodex mites.

This study examines the use of diphenylcyclopropenone in treating alopecia areata patients at the University Hospital Würzburg and investigates how the treatment affects patients' quality of life.

This chapter reviews the presence and roles of stem cells in various body systems, focusing on their lifelong function in animals and humans, and reports no new experimental findings.

In this study, Wnt-3a was found to play an important role in partially maintaining and expanding epithelial skin stem cells in vitro, suggesting potential for in vitro stem cell culture without feeder cells.

Skin-derived stem cells could help treat skin aging and pigmentation issues.

In this study, the activation of Notch1 signaling in keratinocytes was found to play a key role in recruiting immune cells and facilitating skin repair after injury.

This article discusses the anatomical and biological aspects of hair follicle stem cells in the bulge region but reports no new research findings.

The document concludes that doctors should recognize congenital triangular alopecia to avoid unnecessary treatments, as it does not respond to steroids like alopecia areata does.

This dissertation reported that the loss of Ovol2 impairs hair follicle regeneration and wound repair in mice, highlighting its role in regulating directional migration of epithelial cells.
