Stem Cells are specialized cells that are able to give rise to more specialized cells, or differentiate into a specific cell type and appear to be one of
the body's ablest tools for self-repair.
When a disease or injury strikes, these stem cells respond to specific signals and set about to facilitate healing by differentiating into specialized cells required for the body's repair. That is, provided they exist in sufficient numbers and receive the correct signals when disease or injury occurs. When they do not, the end result is an inadequate or compromised healing response. This also relates to the aging process we all go through, the stem cell numbers decrease, as does the plasticity of the stem cells. This results in the inevitable aging of our bodies. Stem cell therapy can slow and rejuvenate aged tissue.
