This chapter describes procedures for isolating and purifying murine epithelial progenitors and assessing their ex vivo propagation capacity, but presents no new experimental results.

This case report describes a 46-year-old man who developed folliculotropic mycosis fungoides, a form of post-transplant lymphoproliferative disorder, following renal transplantation.

This study found that both bFGF and herbal extracts significantly induced proliferation in human hair follicle mesenchymal stem cells, suggesting their potential for promoting hair growth.

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.

This study identified a small population of PAX3+/CD34+ cells in human foreskin tissue that may serve as transition cells between melanocyte stem cells and hair follicle stem cells, characterized by specific marker expressions.

This study detailed distinct immunophenotypic stages of alopecia areata in C3H/HeJ mice, providing an immune blueprint that may help identify therapeutic targets for disease pathways in humans.

CD8+ T cells attack hair follicle stem cells, causing scarring and hair loss in Discoid Lupus.

This study found that germinated hemp seeds extract and exosomes from their calli can prevent androgenetic alopecia by modulating genetic, cellular, and immune responses in hair follicle dermal papilla stem cells and CD8+ T cells, with exosomes being more effective.

In this study, researchers used a mouse model of alopecia areata to demonstrate that both ruxolitinib and baricitinib, oral JAK inhibitors, reduced hair loss, CD8+ cell infiltration, and expression of disease-related markers, with baricitinib showing greater effectiveness.

This study analyzed blood samples from individuals with alopecia areata and found that NKG2D+ immune cells, particularly memory-like NK cells, may better correlate with disease activity compared to CD8+ cells, though significant variability among individuals complicates these findings.

The researchers observed that vitiligo-affected skin shows a selective depletion of NTRK2+ melanocyte subpopulations with progenitor features, which may contribute to poor treatment responses.

This case report details the occurrence of paroxysmal nocturnal haemoglobinuria in a 19-year-old woman with systemic lupus erythematosus to raise clinician awareness of this rare association.

In this study, researchers identified IL18R+ thymus-resident regulatory T cells in mice, demonstrating their unique molecular features and resistance to age- and stress-induced thymus involution, highlighting IL18 signaling's role in Treg migration and retention.

This study investigates whether lymphocytes from mice with secondary alopecia areata can effectively induce the disease in a C3H/HeH mouse model, similar to lymphocytes from mice with spontaneous disease.

This study successfully improved methods for isolating, culturing, and purifying rat hair follicle stem cells, demonstrating their high purity, strong proliferation, and potential for adipogenic and osteogenic differentiation in vitro, which could support advancements in tissue engineering.

In this study, aspartame consumption during gestation in rats was associated with significant histological changes and increased apoptosis in the skin of their neonatal pups.

This study found that androgens decreased splenic macrophage FcgammaR expression and impaired the clearance of IgG-coated cells in an experimental guinea pig model.

This study found that BrdU labeling in Inner Mongolia cashmere goats revealed the presence and localization of stem cells in primary and secondary hair follicles and the epidermis, with signals diminishing after 10 weeks.

This study found that hair follicle stem cells from young rats can be induced in vitro to differentiate into corneal epithelium-like cells using homogenate of rabbit corneal limbal stroma.

This study found that selective adhesion to type IV collagen successfully enriched human hair follicle stem cells based on distinct adhesion properties and marker expressions.

This study found that DNA flow cytometry effectively evaluates physiological and hormonal influences on cell cycle kinetics of human anagen hair bulbs, with increased S phase cells observed in male pattern baldness, hirsutism, and hyperthyroidism.

This study found that Imaging Mass Cytometry effectively visualizes multiple biomarkers in alopecia areata, enhancing analysis of immune cell and tissue interactions in hair pathology.

This study found that topical application of 17 alpha-propylmesterolone significantly increased proliferative activity in hair matrix cells in men with androgenetic alopecia.

In this study, researchers describe a technique for preparing mesenchymal stem cells to optimize hair transplantation for androgenetic alopecia, highlighting future plans to assess stem cell characteristics and hair density improvements through flow cytometry and trichoscopy.

In this study, researchers identified unique prenatal lymphocyte features in human fetal skin, including proliferative naive T cells and memory-like T cells, which may influence antigen and allergen responses in utero and infancy.

Stem cells are in deep skin layers, while differentiating cells are in shallow layers.

Certain NK cell changes in blood may indicate alopecia areata progression.

This study determined that the genome size of Eclipta alba is 4.27 billion base pairs and Aloe barbadensis is 4.42 billion base pairs, providing data for potential future research.

This review discusses advanced techniques for investigating stem cell fate at the single-cell level, including lineage tracing, time-lapse imaging, and molecular profiling, but reports no new research results.

This study found that the RpoN/RpoS pathway regulates gene expression in Borrelia burgdorferi, influencing its ability to persist in mammals and adapt to different hosts.
