Correct me if I'm wrong, but I seem to remember seeing on Quantum
(Australia's T.V. science program) that some researchers in the U.K. (?)
had
managed to get peripheral motor neurons to reproduce in vitro but were
yet
to reproduce the results in a living biological system.  This was about
12-18 months ago and I am pretty vague on the whole thing, but at the
time
was pretty impressed.  Getting any biological matter to reproduce when
it
shouldn't is pretty amazing.

Of course I could be wrong!  I have been before. :)
