This study revealed that in androgenic alopecia, the proximal attachment of the arrector pili muscle to the hair follicle is often lost or significantly reduced.

This study found that immune privilege collapse in the hair follicle bulge and associated immune responses may contribute significantly to the pathogenesis of lichen planopilaris, suggesting a potential autoimmune basis for the disease.

This review examines the literature on the molecular and cellular makeup of the hair follicle niche and how it influences stem cell behavior during hair regeneration, but does not provide new experimental results.

This article discusses the bi-compartmental organization of hair follicle stem cell niches for balancing stem cell cycling and organ growth and proposes similar structures may exist in other adult stem cell niches but reports no new experimental results.

This study found that Wnt/β‐catenin signaling influences the hair follicle regeneration process by prompting quiescent stem cells to enter the cell cycle and is necessary for maintaining the stem cell pool.

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 study found that activating CB1 receptor signaling in human hair follicles increased stem cell proliferation while reducing differentiated cell survival, suggesting CB1's role as a survival stimulus for epithelial stem cells.

Different types of stem cells and their environments are key to skin repair and maintenance.

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

In this study, researchers found that mice lacking the transcription factor FOXC1 in their hair follicle stem cells had increased rounds of hair regeneration but experienced hair thinning due to impaired ability to maintain stem cell quiescence and adhesion.

Nephronectin helps attach muscle cells to hair follicles.

This study identifies a specific cell population, PDGFRα+/Sca1+/CD34+ mesenchymal cells, which play a crucial role in regenerating hair follicles by promoting the downgrowth phase of the hair cycle, offering insights into organ morphogenesis and stem cell niches essential for adult hair regeneration.

This study found that mouse hair follicle stem cells use symmetric cell division for maintenance and fate determination, and identified Gata6 as a crucial factor for their differentiation.

In this study, upper-bulge epidermal stem cells in mouse hair follicles were shown to play a role in forming tactile sensory units by creating an extracellular matrix that supports nerve interactions.

This study demonstrates that hair follicle bulge stem cells can transition into other stem cell compartments, indicating their role in maintaining both hair follicles and sebaceous glands.

This study found that mechanical disruption of the desmosomal cadherin Dsg3 in hair follicle stem cells activates them from quiescence, highlighting its role as a key regulator of stem cell quiescence and epithelial niche integrity.

This study found that depletion of TACE in mouse hair follicles led to impaired stem cell maintenance and hair loss, implicating TACE and EGFR signaling in hair follicle stem cell homeostasis.

This study found that Hopx labels a long-lived progenitor population in hair follicles, which contributes to hair follicle stem cell homeostasis and has an alternative origin from previously thought progenitors.

This review discusses how epidermal Langerhan's cells and dermal cells may influence keratinocyte environments, potentially aiding in the formation of stem cell niches and cellular variety in the basal layer, without providing novel results.

Hair follicle stem cells rely on nearby blood vessels for their maintenance and function.

This study identified several genes highly expressed in germ-line stem cells that are also common in hematopoietic stem cells, potentially aiding the exploration of fundamental stem cell commonalities.

This study found that blocking apoptosis during the catagen phase in mice disrupts hair follicle stem cell niche architecture, delaying subsequent hair regeneration cycles.

This study observed that skin stem cells in dogs could be identified using CD34 and CD200 markers, although further refinement in isolation and cultivation methods is needed for better identification.

This study found that fatty acid desaturation regulated by SCD1 is crucial for hair growth by maintaining hair follicle stem cell niches, with its absence causing abnormal hair growth in mice.

This study found that Shh from neurons signals to Gli1-expressing cells in the hair follicle, cultivating a niche where these bulge cells can potentially transform into epidermal stem cells in wound healing.

Researchers successfully isolated and identified key stem cells in human hair follicles, which could help develop new skin and hair treatments.

Alopecia Areata may involve reduced antioxidant defenses in hair follicles, affecting stem cell function.

This study identified lymphatic vessels as crucial components of the hair follicle stem cell niche, coordinating connections and contributing to hair follicle regeneration in mice.

This study found that stem cells from mouse hair follicles successfully reconstructed the ocular surface in most limbal stem cell deficiency mice, demonstrating potential for treating the condition in a mouse model.

This study reveals that stem cell descendants in mouse hair follicles can return to their niche to retain stemness and function as primary stem cells for future hair cycles.
