This study found that dermal papilla cells may play a critical role in hair follicle development and cycling by promoting epidermal proliferation and potentially mediating systemic factors that influence follicle behavior.

This review discusses the need for more research on how the chronobiological control systems regulate hair follicle cycling and reports no new results.

This study observed that hair follicle mesenchyme in mice exhibits significant plasticity during the hair cycle, with cell migration and changes in papilla size impacting hair production.

Docetaxel, a chemotherapy drug, was reported to cause psoriasis in a patient for the first time.

This case report describes Rumpel-Leede phenomenon in a patient without underlying conditions, occurring after pneumatic compression for venous thromboembolism prophylaxis, with spontaneous resolution upon stopping compression.

This review outlines the histological structures of the skin, highlighting species and regional differences in dermal absorption and obstacles encountered in toxicological assessments due to epidermal thickness variability, contact dermatitis reactions, and stem cell vulnerabilities.

This study found that capillaroscopic patterns varied among patients with systemic scleroderma, psoriasis, psoriatic arthritis, and alopecia, suggesting potential microcirculation disturbances; however, no correlations were observed with serum angiogenic markers.

This study found that NNAT is localized in both undifferentiated and differentiated cells across various rat tissues and has cell-specific intracellular localization, suggesting distinct functional roles.

This study observed that long-term laser hair removal in women may alter hair follicle structures and stem cell interactions, with dermal fibrosis potentially influencing hair regrowth prevention.

This chapter reviews trichoscopic criteria and diagnostic features for various hair and scalp conditions, emphasizing their utility in non-invasive diagnosis, but reports no new clinical results.

This study used transgenic mice to show that disrupting TGF-β signaling in K14+ progenitor cells led to increased stem cell proliferation in the tongue.

In this study, researchers investigated age-related hearing loss in advanced-age CBA/CaJ mice and found combined cochlear damage from chronic sound exposure and metabolic changes linked to oxidative stress, which may require addressing both etiologies for prevention and treatment.

Pax9 is crucial for proper tongue surface development and preventing skin-like changes.

This review examines the regeneration capabilities of skin, oesophagus, and oral mucosa, highlighting the oral mucosa's unique scarless healing properties and the potential of cell therapy to improve scar reduction in wound healing.

This case study describes a rare cutaneous follicular hybrid cyst intimately associated with syringocystadenoma papilliferum, proposing a potential relationship with the infrainfundibulum based on keratin expression.

In this study, researchers found that bulge cells in mouse hair follicles undergo transient proliferation during early anagen, indicating their role as follicular stem cells. However, another factor beyond dermal papilla proximity may be required to initiate a new anagen phase.

This entry does not provide an abstract or new research findings, so no specific results are available for summary.

This study found that dermal papilla cells exhibit stage-dependent variation in histone methylation during the hair follicle cycle and display distinct chromatin marker expression when transitioning to in vitro culture.

Human epidermal stem cells divide faster than previously thought.

Hair follicle dermal stem cells help control hair growth timing by regulating signals at the hair germ–dermal papilla interface.

This study used cashmere goats to reveal distinct intermediate states of dermal papilla cells, each with specific roles in hair growth, shedding, and regeneration.

This study describes a simplified method for isolating and cultivating human hair follicle papillae that can be easily executed by new lab personnel.

This study reports that platelet-rich plasma therapy resulted in temporary hair growth in patients with stabilized Central Centrifugal Cicatricial Alopecia.

This study found that the presence of premature desquamation of the inner root sheath in noninflamed hair follicles is a relatively specific marker for diagnosing central centrifugal cicatricial alopecia.

This study used cashmere goats to map the differentiation of dermal papilla stem cells and identified key intermediate cell states involved in hair follicle regeneration.

In this study, the researchers found that KAP3.1, KRTAP 8-1, and KRTAP 24-1 genes positively correlated with the growth cycle of cashmere in Inner Mongolia goats, aligning with the observed hair cycle phases.

This study suggests that new cells are incorporated into the dermal papilla during the early anagen phase of the hair cycle, which may influence hair growth consistency and follicle size changes.

In this study, researchers found that epithelial cells exhibit density-dependent metabolic heterogeneity, particularly in the pre-epithelial transition stage, where metabolic patterns correlate with cell proliferation and are influenced by actomyosin contractility.

This review discusses the hair follicle cycle's complex regulation and highlights the potential for targeting catagen control in future therapies without presenting new experimental data.

In this study, researchers found that synchronization between expanding epithelial cells and background mesenchymal cells in the mouse hair cycle may be maintained by inhibitory regulation, with potential mediators of this regulation identified.
