Theories of Aging in Stem Biology

Stem cell aging theory states that the aging process is the result of the inability of different types of stem cells to continue to replenish living organisms with different active cells capable of maintaining the original function of that tissue (or organ). Injury and genetic defects remain a problem for systems regardless of age.  creates a better and more efficient way to exchange young people as opposed to older ones. In other words, aging is not a matter of increasing damage, but of failure to recover due to a decrease in the number of stem cells. Stem cells shrink in number and often lose the ability to divide into generations or lymphoid lines and myeloid lines.Maintaining a flexible balance of stem cell pools requires a number of conditions. Balancing growth and peace as well as homing (See niche) and regeneration of hematopoietic stem cells are popular aspects of stem cell pool care while isolation, integration and sensitivity are risk factors. These harmful effects will eventually lead to apoptosis.
