November 2023 in “Nature Communications” This study reported that depleting the pro-apoptotic protein Bax in hair follicle stem cells enables these cells to kill nearby viable cells by sequestering TNFα, which increases the stem cell pool and accelerates tissue regeneration, suggesting potential implications for therapies targeting tissue repair and cancer.

November 2019 in “Mediators of inflammation” This study found that adipose-derived stem cell-conditioned media improved skin flap survival following ischemia/reperfusion injury in mice by increasing cell proliferation and the number of hair follicles, mediated by IL-6.

June 2013 in “Science” This study found that mice lacking the Sept4/ARTS gene had more hair follicle stem cells and improved wound healing, suggesting apoptosis regulation as a potential target in regenerative medicine.

June 2017 in “Stem cell reports” This study found that PTEN regulates the number and genomic stability of hair follicle stem cells in the skin, with its deficiency leading to increased stem cell accumulation and senescence through interactions with BMAL1 and BMI-1.

November 2021 in “Frontiers in Cell and Developmental Biology” This study found that PBX1 overexpression reduces hair follicle-derived mesenchymal stem cell senescence and apoptosis by alleviating ROS-mediated DNA damage, rather than enhancing DNA repair.
