MKI67 and pancreatitis: In contrast, the proliferative response of acinar cell at day 3 after cerulein-induced pancreatitis was markedly reduced in G3 mTerc−/− mice (5.429±2.241 Ki-67-positive cells per high power field, n = 5 mice) compared to mTerc+/+ mice (33.43±5.912 Ki-67 positive cells per high power field, n = 5, p = 0.008, Figure 4A,B).
