March 2021 in “bioRxiv (Cold Spring Harbor Laboratory)” In this study, researchers used an evolutionary-rate-based method to identify genetic elements associated with reduced hair in mammals, finding a dichotomy between accelerated coding sequences and noncoding regulatory elements influencing hair growth.
November 2025 in “Archiv für Pathologische Anatomie und Physiologie und für Klinische Medicin” This study examined 16 sporadic trichoblastic tumors and found that although one showed malignant transformation, clinical follow-up revealed no residual or metastatic disease. RNA sequencing indicated a high tumor mutational burden and absence of a UV-related signature, helping to distinguish these tumors from similar growths.
September 2025 in “Digital Commons - RU (Rockefeller University)” 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.
February 2025 in “Biomolecules” This research found that melatonin has a bidirectional effect on hair follicle stem cell survival, improving it at low doses and inhibiting it at high doses.
January 2025 in “Dermatology Practical & Conceptual” In this study, researchers identified four gene variants that may contribute to androgenic alopecia and vitiligo, proposing a novel di-genic inheritance model that could help guide genomic approaches for personalized treatment and early diagnosis.
January 2025 in “Frontiers in Cell and Developmental Biology” This study explored the molecular mechanisms determining the identity of keratinocytes and corneal epithelial cells, finding that miRNAs from the Gtl2-Dio3 region, which regulate key signaling pathways, play a significant role in cell identity through the Hox/Gtl2-Dio3 miRNA axis.
January 2025 in “BMC Genomics” This study examined the role of long non-coding RNAs in wool fineness among Gansu alpine fine-wool sheep, identifying specific lncRNAs and target genes that may enhance wool quality.
September 2023 in “Cureus” This study reviewed early research on topical finasteride for androgenetic alopecia, finding it appears safe and promising, though further investigation is needed to determine optimal dosing, frequency, and potential applications for other types of alopecia.
April 2023 in “The journal of investigative dermatology/Journal of investigative dermatology” This study concluded that KLF4 is a crucial regulator of hair follicle stem cell quiescence and may work by interacting with multiple transcription factors to control related genes.
December 2022 in “Scientific Reports” This study found that transplanted hair follicle-associated pluripotent stem cells in mice differentiated into keratinocytes and stimulated hair growth by producing mature hair shafts.
May 2022 in “The journal of immunology/The Journal of immunology” This study developed a foxn1-deficient Xenopus laevis model using CRISPR/Cas9, observing reduced T-cell markers and altered immune responses in tadpoles, providing a nonmammalian model for immunological research.
This article reviews the history and characteristics of the rare nude phenotype SCID, primarily distinguished by severe T cell immunodeficiency and notable skin and hair abnormalities, but reports no new clinical findings.
April 2021 in “Journal of Investigative Dermatology” This study found that skin bacteria promote regeneration in wound-induced hair follicle neogenesis, suggesting a role for IL-1β signaling and challenging the belief that infection inhibits healing.
March 2021 in “bioRxiv (Cold Spring Harbor Laboratory)” This study found that the absence of Hif-p4h-2 in specific mouse skin cells disrupted hair follicle development, leading to hair loss due to irregular keratin formation and pathway signaling.
May 2018 in “The journal of immunology/The Journal of immunology” This study identified that patients with compound heterozygous mutations in FOXN1 exhibited severe T-cell lymphopenia but retained normal hair and nail development, indicating a distinct clinical phenotype from classic FOXN1 cases.
May 2017 in “The journal of immunology/The Journal of immunology” This study reported that patients with specific Foxn1 mutations exhibited severe T-cell lymphopenia without the hair and nail abnormalities usually associated with these mutations.
February 2016 in “Science” This research found that Foxc1 promotes quiescence in hair follicle stem cells and identified COL17A1 depletion, due to DNA damage, as a cause of hair thinning and loss during aging.
January 2015 in “CU Scholar (University of Colorado Boulder)” This research found that Foxc1 is critical for maintaining quiescence in activated hair follicle stem cells and that the cancer cell-of-origin influences tumor heterogeneity in mouse skin squamous cell carcinoma.
December 2004 in “PLoS ONE” In this study, the Foxn1(-/-) nude phenotype was associated with an altered regulation of epithelial progeny in skin, offering a valuable model for investigating stem cell niche maintenance and regulation.

,
May 2016 in “Matrix Biology” In this mouse study, researchers found that the absence of laminin-511 in skin delays hair follicle development and disrupts hair shaft differentiation, affecting key transcription factors for hair keratins.
16 citations
,
April 2021 in “International Journal of Molecular Sciences” This study found that micro-current electrical stimulation may promote hair growth in human hair follicle-derived papilla cells and a mice model by enhancing cell proliferation, migration, and activating key growth pathways.
March 2026 in “Journal of Zhejiang University (Medical Sciences)” This study reported that in mice with rapamycin-induced thymic atrophy, Angelica sinensis promoted thymic cortical regeneration and functional recovery by activating the Wnt/CTNNB1/Foxn1 signaling pathway and improving inflammatory microenvironment, suggesting its potential benefit against immune aging.
January 2026 in “Pediatrics International” This report examines the cautious approach to administering live vaccines to an infant with a heterozygous FOXN1 variant, noting the importance of monitoring TREC levels and immune function indicators in guiding vaccination decisions in such cases.

February 2016 in “Science” 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 of foxes and jackals in Ilam province, Iran, 19.35% of foxes and 17.85% of jackals were found to be infested with ectoparasites, mainly Ctenocephalides canis.
January 2005 in “Jukuri (Natural Resources Institute Finland (Luke))” This study found that lower dietary protein with supplemented methionine allowed blue foxes to grow normally and produce high-quality pelts while reducing feed costs and environmental phosphorus and nitrogen loads.
