November 2022 in “Journal of Investigative Dermatology” This study reported that an ex vivo organ culture system effectively induced aging-related changes in healthy human skin, allowing testing of senolytics like tretinoin, resveratrol, and caffeine.
November 2022 in “Journal of Investigative Dermatology” This study found that dysregulation of the DNA damage response in stem cells is a common factor of aging, affecting tissues like the skin, brain, kidneys, and intestine.
April 2023 in “Journal of Investigative Dermatology” This study found that mitochondrial dysfunction in the epidermis contributes to aging-related changes in hair follicles among mice, with aged mice showing reduced hair density and delayed regrowth, suggesting that maintaining mitochondrial function may help prevent age-related organ decline.
