This study found no significant difference in serum ferritin levels between individuals with androgenetic alopecia and healthy controls, but reported lower ferritin levels in those with premature alopecia compared to adult-onset cases.

This study found that squamous cell carcinomas from hair follicle stem cells are more prone to epithelial to mesenchymal transition and metastasis than those from interfollicular epidermis, due to distinct chromatin landscapes.

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.

Delta1 is crucial for controlling skin cell growth and preventing tumors in mice.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

This study found that hair follicle and interfollicular epidermis stem cells contribute differently to skin regeneration, with their persistence influenced by factors like spatial constraints and competition moderated by Notch suppression.

This study found that follicular stem cells in hair follicles are more sensitive to the antiproliferative effects of glucocorticoids compared to basal keratinocytes due to incomplete desensitization.

This study found that Lgr6+ stem cells in mice are not major initiators of UV- or chemically induced skin tumors.

Hair follicles are crucial for maintaining skin barrier function.

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.

This case report describes a presumptive case of ichthyosis fetalis in a cross-bred lamb and highlights the need for this rare condition in sheep to be considered by veterinarians in the differential diagnosis of dermatopathies.

This study found that type XVII collagen (COL17) regulates interfollicular epidermis proliferation in both neonatal and aged mice through Wnt signaling, suggesting its potential as a target for anti-aging skin strategies.

This study found that Lgr5 and Lgr6 stem cells both activated wound-healing genes, but only Lgr5 stem cells changed their identity to contribute to new skin formation during wound repair.

This study found that COL17 deficiency in neonatal mice causes abnormal skin cell proliferation due to disrupted Wnt signaling, while replenishing or overexpressing COL17 can reverse this effect in both neonatal and aged skin.

This study found that Krox20 marks a diverse stem cell population in mouse hair follicles, which significantly contributes to the interfollicular epidermis and regulates epidermal homeostasis.

This study found that type XVII collagen is crucial for regulating epidermal cells' proliferation in mice and may be a promising target for anti-aging skin treatments.

This study established a 3D in vitro culture system of canine keratinocyte organoids to study epidermal function and address skin disorders in dogs, though additional growth factors are needed for hair follicle development.

This study identified specific markers that can distinguish between stem cells in different regions of human scalp hair follicles, offering potential strategies for cell sorting and purification based on these markers.

This study identified that the Wave complex proteins ABI1 and Wave2 play a crucial role in regulating epidermal shape and growth during skin development, notably influencing SOX9 expression and Wnt signaling pathways.

This review examines the complex mechanisms that regulate skin stem cell development, activation, and differentiation, emphasizing the molecular signaling pathways that influence their fate and contribute to skin homeostasis.

This review discusses the heterogeneity and plasticity of epithelial stem cells in skin homeostasis, wound healing, and tumorigenesis, reporting no new results but emphasizing the need for further exploration of key regulatory mechanisms.

This study mapped gene expression in different skin structures of dogs, finding similarities to humans that support using dogs as models for human skin diseases.

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 chapter reviews the biology and regulatory mechanisms of epidermal stem cells, emphasizing their heterogeneity and roles in skin homeostasis, cancer, and aging, without reporting new findings.

This study found that in mice, the epidermal microenvironment reverses the oncogenic effects of GNAQQ209L in melanocytes, inhibiting their survival and proliferation through paracrine signals.

This study introduces a method for long-term expansion of adult mouse epidermal stem cells in vitro using an organoid culture system that maintains the basal-apical organization.

In this study, researchers identified Tenascin-C as a marker for touch dome keratinocytes, which maintain themselves and can develop into Merkel cells following injury, showing they share molecular traits with various epidermal keratinocytes.

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.

In this computational study, the researchers observed that compounds in rosemary extract showed promising interactions with proteins involved in androgenic alopecia, suggesting potential for hair growth promotion and hair loss prevention, warranting further in vitro and in vivo validation.

This review discusses skin disorders in women of color, highlighting unique presentations like dyschromias from acne, and underscores the need for more research on racial and ethnic differences; it reports no new clinical results.
