September 2022 in “Journal of Theoretical Biology” This study developed a mathematical model to explore hair follicle regeneration mechanisms, showing that low spontaneous apoptosis rates help regenerate hair follicles after ionizing radiation, while high rates lead to degeneration during the catagen phase.

March 2013 in “Development” This study found that Hopx labels a long-lived progenitor population in hair follicles, which contributes to hair follicle stem cell homeostasis and has an alternative origin from previously thought progenitors.

April 2020 in “Journal of Clinical Investigation” This study found that hair follicle stem cells from hidradenitis suppurativa patients showed alterations in cell cycle regulation and DNA replication, potentially linking genetic predisposition to the skin inflammation characteristic of the disease.

December 2005 in “BioEssays” This study found that Wnt/β‐catenin signaling influences the hair follicle regeneration process by prompting quiescent stem cells to enter the cell cycle and is necessary for maintaining the stem cell pool.
In this study, various cellular responses and signaling pathways were examined in hair follicles after exposure to ionizing radiation, including the effects of Wnt3a treatment, with findings noted in apoptosis, DNA damage, and differentiation processes.
