Sorry, I neglected to include the second Econmist article in my message last night. It is from 22 March issue and covers Good Samaritan Hospital, Los Angeles and l'Hopital Henri Mondor in Paris where transplants of fetal striatum are being done. Also Harvard where pig fetal tissue has been tried. To me the important part of the issue was the statement that "recent research has shown that adult neural stem cells are alive and can be prompted to recreate lost cell populations by growth factors " - work done at Neurospheres in Canada. I just realized I didn't copy the remainder of the article. I'll do so today. Sorry. Allan Goldman [log in to unmask]
