The stem cell theory of aging postulates that the aging process is the result of the inability of various types of stem cells to continue to replenish the tissues of an organism with functional differentiated cells capable of maintaining original function of the tissue. Anti-Aging is the process or method that is intended to prevent or limit the process of becoming old. Enduring youth might be attained if aging could be stopped at a youthful age, but it seems unlikely that the damage to organs, tissues, cells, and molecules known as aging can be stopped completely by replacing or repairing those damaged organs, tissues, cells and even molecules seems like a better strategy. These strategies can restore function to old organisms or can even rejuvenate. In many tissues, there is an age-related decrease in undeveloped cell usefulness however not an exhaustion of Stem Cells. Such discoveries have significant consequence for the stem cell-based treatment of the age-related disorder.
