Christopher,
If umbilical cord blood mononuclear cells UCBMC and lithium show any benefit, it will become the standard therapy. It UCBMC is effective, further clinical trials would compare new therapies against UCBMC+Li. We are of course now looking at the next set of therapies. It takes years to prepare therapies for trial. Believe me, I have no interest in holding back any therapy if data supports its use.
Wise.
