Stem cells are called the master cell. We all originated from one cell when we were developing. From that one cell it multiplied into many cells and eventually those cells differentiated into our organs muscles and bones.
Stem cells are blank cells that can differentiate into any cell in the body and heal almost every cell in the body. It will literally re-grow new cells in the damaged area. If you suffer from arthritis torn muscles or ligaments this may be a long term treatment other than expensive surgeries which require a long healing process. Most surgeries are not permanent and may require more than one surgery in the future.
