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.

This study found that when NFIB was removed in adult mouse hair follicle stem cells, it did not affect their maintenance but unexpectedly led to increased proliferation and differentiation of nearby melanocyte stem cells.

This case report describes the youngest known patient with viral-associated trichodysplasia of immunosuppression, where systemic valganciclovir therapy improved facial papule eruptions following cardiac transplantation.

This study found that c-Jun is essential for vitamin D receptor expression, and the vitamin D receptor inhibits c-Jun-dependent cell death through non-classical mechanisms independent of vitamin D3.

This review discusses the role of sex hormones in COVID-19 severity and reports no new clinical results; the authors suggest further research for gender-based personalized treatment options.

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 confirmed omalizumab's safety but noted that hair loss was more prevalent than previously reported, with side effects influencing treatment decisions especially in patients with reduced medication effectiveness.

This review examines the role of IL-15 in alopecia areata treatment but reports no clinical results, as there are currently insufficient studies to determine its therapeutic potential.

This study found a high concordance between subject-reported and clinician-reported Fitzpatrick Skin Phototypes, but 14% of subjects misjudged their skin type, often overestimating it.

This study found that a significant portion of the Beyond-COVID cohort reported persistent symptoms, with Omicron variants showing lower rates and severity of symptoms compared to other variants.

This study found that patients with frontal fibrosing alopecia showed significant alterations in protein expression in forehead corneocytes, suggesting the condition may have systemic implications beyond the scalp.

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

This study found that proteomic analysis can distinguish hair samples across different ethnicities and body regions based on keratin protein levels, which may aid forensic hair identification.

Proteomic analysis can identify genetic differences in mouse hair, helping understand hair defects and variations.

The researchers identified a specific mutation in the desmoglein 4 gene linked to localized autosomal recessive hypotrichosis, which presents with variable hair loss severity in affected individuals from a large Pakistani family.

This study found that genetically variant peptides from human hair can reliably identify individuals despite differences in age and storage conditions, provided environmental and processing factors are controlled.

This study identified the Itpr3 gene as responsible for the tufted hair loss phenotype in the BTBR mouse strain.

This study found considerable variation in hair shaft proteomic profiles among Caucasian, African-American, Kenyan, and Korean subjects, with individual and site-specific differences observed.

This study used proteomic profiling to reveal significant individual and site-specific differences in human hair shaft proteins, which may improve the differentiation of hair based on ethnic origin and individual identity.

This review discusses sex-based differences in immune responses, focusing on genetic, hormonal, and microbiome factors influencing infections like COVID-19, and reports no clinical results.

This study found that the ablation of Esrp1 and Esrp2 disrupts epithelial tight junctions by affecting Arhgef11 isoform expressions, highlighting a potential mechanistic link between splicing alterations and epithelial barrier defects.

This article reviews the biology of epithelial stem cells and their role in tissue self-renewal, maintenance, and regeneration, and it highlights the clinical implications of understanding their signaling pathways, but it presents no new clinical findings.

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 research discusses how epithelial stem cells in the skin maintain normal homeostasis, contribute to wound repair, and highlights the importance of these processes, as defects can lead to skin diseases including cancers, but provides no new experimental results.

This review explores the role of TGF-β superfamily pathways in stem cell environments and their implications for tissue regeneration and cancer development, reporting no new experimental results.

This review explores the mechanisms of adult stem cell self-renewal, using skin as a model, and reports no new results but raises important unanswered questions in the field.

This essay discusses the establishment, maintenance, and role of skin stem cells in tissue homeostasis, wound repair, and their relation to skin cancer, without reporting new experimental findings.

This review discusses the pharmacological properties of progestins used in contraception and hormone replacement therapy, focusing on drospirenone's unique effects, but reports no new experimental findings.

This article reviews recent advancements in understanding skin stem cells and their roles in maintaining epidermal homeostasis and repairing wounds, without presenting new experimental findings.
