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.
