This review discusses the relationship between psoriasis and autoimmunity, focusing on autoimmune co-morbidities, but reports no new research findings.

This study found that disrupting Stat3 in keratinocyte stem cells of mice reduced skin tumor formation by approximately 80%, suggesting Stat3's role in tumor initiation survival mechanisms.

This study found that lymphatic vessels in mice are important for hair follicle development and organization, as their depletion blocks hair growth.

This review discusses the embryonic origins and characteristics of various stem cell populations in the skin, but it provides no new experimental results.

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 sweat gland stem cells primarily maintain sweat gland homeostasis but can trans-differentiate to aid in epidermal healing and regenerate diverse skin structures under certain conditions.

In this study, epidermal Notch activation increased jagged 1 expression, leading to skin changes like thickening and blistering, with these effects inhibited when jagged 1 was absent.

This study found that collagen VI influences hair follicle growth and wound-induced regrowth by activating the Wnt/β-catenin signaling pathway in mice, suggesting potential therapeutic targets for hair loss.

This study suggests that canonical BMP signaling, particularly involving Smad1 and Smad5, plays a critical role in hair follicle stem cell regulation and hair morphogenesis, with distinct roles from pSmad8.

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.

In this study, loss of epidermal Par3 in mice disrupted the skin barrier and affected cell differentiation and stem cell maintenance, highlighting its role in epidermal homeostasis.

This review discusses the identification and roles of different epidermal stem cell types in skin homeostasis and repair, and reports no new experimental findings.

This study found that applying topical imiquimod during mid and late telogen in mice activates hair follicle stem cells and influences immune cell infiltration, promoting hair cycle entry independently of Wnt signaling.

This review explores recent insights into how intrinsic gene oscillations and molecular interactions in hair follicle stem cells contribute to their regenerative potential, with potential implications for regenerative medicine, but reports no new clinical results.

In this study, researchers reported that CD34 expression in the isthmic region of canine hair follicles suggests a potential stem cell compartment in this area.

This article reviews the role of adult stem cells in tissue homeostasis and wound repair, focusing on their regulation within the murine hair follicle's specialized niche, but it presents no new findings.

This review discusses how inflammation influences hair follicle stem cell activities like wound healing and follicle cycling and suggests a potential link between inflammation, stem cell activation, and programmed cell death.

This study found that their system effectively supports the rapid formation of human hair follicle organoids, providing a platform for studying hair regeneration and drug screening.

This study found that the postnatal thymus contains a population of mesenchymal stem cells that may help maintain functional thymic microenvironments.

In this study, researchers discovered that ROR2, a Wnt receptor, plays a crucial role in regulating hair follicle stem cell self-renewal and maintenance, compensating for the absence of β-catenin.

This study found that the patch assay effectively reconstituted mature hair follicles using culture-expanded human fetal cells and may serve as a method to assess cell trichogenicity.

This study provides evidence that long-term deregulation of the circadian rhythm in humans affects the regenerative properties of skin and hair precursor cells by altering clock pathway protein expression.

This review examines the challenges of hair follicle regeneration and outlines strategies for bioengineering human hair follicle models, without presenting new experimental results.

This study found that overexpression of sPLA2-IIA in homozygous mice resulted in cyclic alopecia, a halt in hair follicle cycling, and impaired wound healing due to complete loss of hair follicle stem cells.

This study found that PRC2 plays a non-instructive role in adult hair follicle stem cells, with its loss not affecting quiescence or cell identity, despite upregulation of genes linked to activation.

Different stem cells have benefits and challenges for tissue repair, and more research is needed to find the best types for each use.

This study highlights that human hair follicle dermal papilla cells and glypicans play crucial roles in regulating hair follicle stem cell differentiation.

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 examines the role of hair follicle stem cells in epidermal regeneration during skin soft tissue expansion, proposing a potential method for their cellular and molecular regulation.

In this study, the researchers found that deleting ceramide synthase 4 in the skin's epidermis alters stem cell differentiation, disrupting hair follicle structure and barrier function, potentially leading to immune responses similar to atopic dermatitis.
