Hi Sean
You may be interested in details of this stem cell research and trial:
fp7merlin.euWhilst specifically aimed at PSC my hep (who is one of the researchers) has confirmed that, if it works, it would help all types of liver inflammation.
Quite a few people here in UK with PSC get transplants by the way. Our big problem though is lack of donors. Who would have thought that low road deaths would have a downside?
