This study used single-cell RNA sequencing to create a detailed atlas of human scalp hair follicles and found that early-stage hair graying involves matrix hair progenitor depletion linked to P53 pathway activation.

This study reports that low levels of HDL cholesterol and IGF-1 were associated with a higher risk of hair loss in middle-aged women, but causal relationships remain uncertain.

This study found that AP-2α and AP-2β transcription factors are crucial for maintaining adult skin homeostasis, with their inactivation in keratinocytes leading to impaired differentiation, hair abnormalities, and inflammation, highlighting their key regulatory roles.

This study found that disrupted cholesterol homeostasis impairs hair regrowth in individuals with primary cicatricial alopecia by damaging hair follicle stem cells, highlighting the importance of cholesterol in maintaining stem cell function and hair follicle integrity.

This review discusses potential causes of alopecia and hair overgrowth in pediatric patients, detailing diagnostic techniques and treatments, but presents no new research findings.

Lgr5 is a marker for active, long-lasting stem cells in mouse hair follicles.

Different types of long-lasting stem cells are responsible for the growth and upkeep of the mammary gland.

This study found that differentiated airway epithelial cells can revert into functional stem cells in vivo, suggesting a more general role for this dedifferentiation process in tissue regeneration in higher vertebrates.

This study reports the first instance of skin autotomy in mammals, specifically in African spiny mice, and suggests they may possess a greater regenerative capacity than previously understood, possibly offering insights for regenerative medicine.

This study developed molecular signatures for dermal papilla cells and their niche, uncovering novel signaling regulators and genes linked to hair disorders, which may inform future hair development research.

This study found that castration-resistant prostate cancers resistant to CYP17A1 inhibitors may still depend on steroids and could respond to therapies targeting de novo intratumoral steroid synthesis.

This document extends previous recommendations by the National Lipid Association for managing dyslipidemia, focusing on lifestyle therapies, special patient groups, and strategies to enhance adherence and patient outcomes.

This study found that stabilized beta-catenin is crucial for activating stem cell transition from quiescence to proliferation in hair follicles by influencing gene expression within the stem cell niche.

This review discusses advances in forensic DNA profiling, highlighting new genetic markers and methods for identifying unknown individuals, but reports no new research findings.

This study found that, in mouse tail epidermis, stem cells rapidly activate and regenerate new progenitors to repair wounds, with mechanisms affecting their proliferation, differentiation, and migration.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

This review discusses the cutaneous serotoninergic/melatoninergic system's potential role in skin function and resilience against environmental and internal stresses, but does not report new experimental findings.

This study found that IL-17A-producing γδ T cells play a key role in bone fracture healing by promoting bone formation, with deficiencies leading to impaired repair in mice.

This article reviews the design and objectives of the Rotterdam Study, as well as summarizes major findings, without reporting new results.

This study found that super-enhancers are essential for hair follicle stem cell identity, lineage commitment, and plasticity in mice, with SOX9 being a key regulator of these chromatin dynamics.

This study found that induced expression of mir-302 can reprogram human hair follicle cells into induced pluripotent stem cells through a novel epigenetic mechanism involving global demethylation.

In this study, researchers found that wound healing in mouse skin recruits diverse fibroblasts, including myeloid-derived cells, which contribute to regenerating adipocytes.

This study found that the circadian clock regulates the activation state of murine epidermal stem cells, affecting tissue homeostasis and susceptibility to tumorigenesis when disrupted.

This study found that altering cell culture conditions to form three-dimensional papilla spheroids can restore the ability of human dermal papilla cells to induce hair growth in adult skin.

This study demonstrates that bioengineered lacrimal gland germs can successfully develop and restore tear production and ocular surface protection in a mouse model with lacrimal gland dysfunction.

This study found that Wnt1/βcatenin signaling plays a crucial role in activating the epicardium and cardiac fibroblasts, which supports cardiac repair following acute ischemic injury.

This research found that Foxc1 transcription factor and COL17A1 are critical in regulating quiescence and hair thinning in hair follicle stem cells, with aging-related DNA damage leading to hair loss.

In this study, researchers developed a microfluidics-based method for creating uniform, size-controlled stem cell spheroids that enhance osteogenic differentiation when encapsulated in alginate-RGD microgels.

This study found that adipocytes play a crucial role in skin wound healing by facilitating fibroblast recruitment and dermal reconstruction during the healing process.
