April 2002 in “Animal Science” This study found that intradermal spermidine injections stimulated cell proliferation and increased fibre length growth rate in wool follicles of Merino lambs, without significantly affecting fibre diameter.
November 2025 in “Nature Communications” This study used a 3D live imaging system to map cell dynamics in human hair follicles, revealing patterns of cell movement and division that help explain hair fiber extrusion during hair growth.
December 2022 in “bioRxiv (Cold Spring Harbor Laboratory)” This study found that inducing miR-205 reduces actin contractility and stiffness in hair follicle stem cells and progenitors, stimulating hair regeneration in both young and old mice.
April 2010 in “Cancer Research” This study found that altering CDK4 expression in mice affects the population of keratinocyte stem cells, suggesting a correlation with susceptibility to skin papillomas.
