Scientists have discovered that a topical anti-aging drug called ABT-263 can dramatically improve wound healing in older skin. The treatment works by removing damaged “senescent” cells that accumulate with age and slow the body’s repair process. In aged mice, wounds healed much faster after treatment, while the drug also activated genes tied to collagen production and tissue regeneration.
A drug designed to eliminate worn out, aging cells may help older skin recover from injury much faster, according to research published in Aging (Aging-US). The work, titled “Topical ABT-263 treatment reduces aged skin senescence and improves subsequent wound healing,” suggests that targeting “zombie cells” in the skin could one day improve healing after surgery, injury, or chronic wounds in older adults.
