April 2024 in “The journal of investigative dermatology/Journal of investigative dermatology” In this mouse model study, researchers found that deleting the ASH2L gene in epidermal progenitor cells led to thinner epidermal layers, delayed hair follicle development, and reduced epidermal stem cell pools, with alterations in genes related to hair follicle development and the Notch signaling pathway.

August 2025 in “Epigenetics & Chromatin” This study explored the role of the histone modification H3K4me3 in cashmere goat dermal papilla cells, finding that increased levels enhanced cell proliferation and activated Wnt signaling genes, suggesting H3K4me3's involvement in hair follicle development through regulation of the gene RSPO3.
May 2026 in “Nature Communications” This study observed that the loss of H3K9me3, via the ablation of Suv39h1, Suv39h2, and Setdb1 in embryonic mouse epidermis, disrupts skin development processes such as keratinocyte differentiation and hair follicle formation, highlighting H3K9me3's crucial role in epidermal morphogenesis.
March 2026 in “Scientific Data” This study mapped the genome-wide epigenetic landscape in secondary hair follicle stem cells of goats, revealing distinct histone modification signatures associated with cashmere fiber cycling during different stages of hair growth.
