Yamanaka factors, a group of proteins that can reprogram differentiated (mature) cells into pluripotent stem cells, may be a therapeutically novel way to reverse cellular aging. Following an "interrupted" pattern of reprogramming where cells retain their cellular identity, rather than cross-differentiating to a different lineage or reverting to a stem cell, may allow a type of epigenetic return to youthfulness, but without the cellular identity crisis. When cells lose their cellular identity, Dr. Horvath explains, this carries some cancer risk. In support of this hypothetical approach, a study using a mouse model of premature aging showed that short-term expression of four of these factors ameliorated cellular and physiological hallmarks of aging and prolonged lifespan. Other research has demonstrated that resetting aging cells to a youthful state in animal models produced fewer signs of aging and longer lifespans. These findings suggest that reprogramming may one day be a viable anti-aging intervention for use in clinical settings. In this clip, Dr. Steve Horvath describes how cellular reprogramming transforms old cells into younger ones.
