As a computer scientist, I have no expertise in it. But my understanding is that a stem cell is an 'undifferentiated' cell. It hasn't been 'programmed' yet, to tell it what it should grow into. And as such, can grow into any type of cell in our body. I just don't know how we actually tell it what to grow into. For instance, as an embryo, you start as a single cell, it divides, eventually some of those cells need to start specializing, but until then they all have the potential to be any type.
