Thanks for taking a closer look, Kaz!
I totally agree with Kaz - it may provide a treatment eventually but there is little evidence and large risks not least of which is that sending stem cells abroad is illegal so to get your stem cells cloned you need to go to the labs, at present only Korea is offering such therapy and the director of the company has been prosecuted for transpoting stem cells across international borders.
Here are some references to the trials I've found the first one SS in mice models is the most interesting but no follow up trails in humans that I can find if any one finds such trials please post here.
The second one from the BMJ is showing the opposite!!!
The last article below discusses why the results are so contradictory

THIS IS A PARTICULARLY GOOD OVERVIEW OF IMMUNE SYSTEMS AND STEM CELL RESEARCH IN A.I. DISEASE RECOMMENDED READING FOR ANYONE INTERESTED- not too techie and a nice simplified overview of the immune system well done NIH!

Note yet again the general lack of research into Sjogren's compared with other a.i. diseases we truly are the "forgotten pateints"
