Stem Cell Culture

I think it was about four years ago when I first heard about stem cell technology.  Scientists then were researching for the potential of these cells to cure major diseases.  But now, stem cell culture has become very popular because it is now used as an ingredient in beauty products.  Stem cells are believed to turn back the clock.  No wonder beauty product manufacturers are adding this ingredient in their products.  I'm more interested in stem cell culture for health purposes.  My dad is diabetic and my father in law is suffering from heart disease.  I am hopeful that this medical breakthrough will be able to help them.
