Aging is characterized by the gradual decline of cells and tissues, leading to changes in their function and communication.
Scientists have developed cocktails of chemicals to reverse cell age by controlling gene behaviour without altering DNA.
Researchers have tested these chemicals on human cells from various ages and conditions, including premature aging, to study their impact on aging.
They found six chemical mixtures that rejuvenated cells without altering their DNA, indicating the potential for reversing aging.
