Declining stem cell function is undoubtedly an important contribution to degenerative aging and age-related mortality. Tissues require the supply of new somatic cells that is generated by stem cells in order to replace losses, repair damage, and maintain function. Unlike stem cells, somatic cells are limited in the number of times they can divide. Turnover of somatic cell populations is a...
