well that's a great point, there is adult stem cells
and umbilical cord stem cells. all the research is
ongoing with those. the controvsy is maionly with
embryonic stem cells and then only with the federal
funding of that. 
i'll get into part of my response on the embryonic
cells after i wait to see if i can pick up the lost
response to kendall's email. i am afraid i'll have to
redo it. and it is raining and my hands are sore
today.
