Learning objectives – to learn what stem cells are
and how they can be used
Stem cells are cells that can turn into cells. The scientific term for this is
undifferentiated. Differentiated cells have already become specialized and
will now carry out a certain job within the body.
In animals the ability to stay undifferentiated is lost at an early stage therefore
it is very difficult to gain stem cells as they specialize very early in the process.
The majority of stem cells are found in embryos, they are of much use in the
medical context as they can be used to cure many diseases and organ defects
as the stem cells have the possibility to form any other cell.
Adults also have stem cells, they are only found in the bone marrow, and
however they are not as useful as the stem cells found in the embryos as they
do not have the ability to form any cell on certain ones
