Stem Cells

When my teacher first said that we were studying stem cells at first I was confused about what they were.  It wasn't long before I got the basic concepts.  They are basically cells that can turn into any kind of cell.  With this fact they could change the way we treat injuries.  With this technology you could regrow parts of the body.  There are examples of this in animals such as star fish and salamanders.  These cells in general could just heal injuries fast and take the place of damaged cells.  This concept is very interesting and it will be a good thing for us people whenever the scientists learn more about it and we can start using it.
