INS and diabetes mellitus: Two weeks after anti-CD3+MK626 treatment, the proportion of insulin+Ki67+ β-cells in the islets was increased to 1.22±0.35% in pancreata of cured mice (p<0.05 vs. new-onset, p<0.01 vs. longstanding diabetics and p<0.01 vs. age-matched normoglycemic NOD-scid mice, Fig. 6B) but not statistically different to values found in pancreata from mice cured by anti-CD3+placebo therapy (0.94±0.31%).
