Doctors at Imperial College, London have published results showing improvement in patients with alcoholic liver cirrhosis, after treatment with their own adult stem cells. Nine patients had their adult stem cells from blood collected, the numbers were boosted in the lab, and then the cells were injected into their livers. Positive results were seen within one week. Seven of the nine patients showed significant improvement up to 12 weeks (the extent monitored for this study), with three patients showing almost complete resolution. Dr. Nagy Habib, the senior author, said "We are encouraged that the majority of patients in this study experienced a significant improvement in their liver functions." These latest results were published in the American Journal of Gastroenterology.

The new results using adult stem cells to treat liver damage are a follow-up to previous work done by Habib's group and reported in 2006 and in 2007. Positive results using adult stem cells to treat liver damage in patients has also been reported by another group in Greece and in Japan.
