University of Florida researchers restored normal blood sugar levels in diabetic mice for three months by transforming bone marrow stem cells into islet-like cells that produced normal insulin levels Oh SH, et al, Adult bone marrow-derived cells trans-differentiating into
insulin-producing cells 
for the treatment of type I diabetes, Lab Invest 84, 607-617, May 2004
2003
Researchers used spleen cells to help regenerate pancreatic islet cells that produced insulin and permanently reversed diabetes in mice The lead researcher stated that using this procedure patients with fully established diabetes possibly could have their diabetes
reversed BBC News Online, 14 November 2003, and is ready to test the approach in clinical trials Kodama S, et al, Islet regeneration during the reversal of autoimmune diabetes in
