What is a stem cell?

A stem cell is a brand-new cell known as a precursor cell that has not yet determined which cell it will become. When a cell is in this state, it has the remarkable ability to assist other cells in regeneration, control inflammation that leads to pain and further damage to tissue, and direct many others cells critical in the development of new tissue. They function somewhat like a coach for a football team as they direct many critical plays to win the game of tissue repair. It is important for patient to understand that stem cells do not just simply differentiate into new tissue but direct the whole process of tissue repair of existing cells and regeneration of new ones.
