Today, another research group announced their entry to the field of senescent cell clearance as a means to treat aging, along with the intent to commercialize their novel method of achieving selective destruction of senescent cells in aged individuals. Senescent cells accumulate with age as a result of the normal operation of living tissues: cells become senescent when damaged or when they reach the Hayflick limit on replication. Near all are destroyed, either through the programmed cell death mechanism of apoptosis, or by immune cells attracted by the signal molecules generated by senescent cells. Unfortunately, some linger, resistant. The number of these cells grows over the years, and the signals they generate start to create harmful outcomes in nearby cells and tissue structures, and in addition spur rising levels of chronic inflammation. The increasing presence of senescent cells is one of the root causes of degenerative aging and directly contributes to many specific age-related diseases.
