Our patients and readers typically experience a few waves of shock when learning about stem cells, particularly stem cell therapy.
Realizing that stem cells are a natural component of our body rather than some new, miraculous innovation is the first major epiphany. To put it very broadly, each and every one of us was once nothing more than a few stem cells.
The second surprise comes when you discover that stem cells can be extracted from your body and can differentiate into a variety of mature cells that your body requires for regeneration and healing.
