Subject: Can scientists 'make' red blood cells, white cells, or any other cells?

Can we do this putting molecules or atoms together if we know the atomic 
structure of a blood cell or any other cell, like a brain cell?  I was told 
that simple organic structures could be made this way, are these cells in the 
human body considered "simple" organic structures or are they too complex 
to "make" using this method of putting molecules and atoms together?  Thank you 
so much!!!!!!  For a project that is due soon.  Thanks for any help!!!!!!!
