To determine the effect of diabetes on reproductive performance, two kinds of diabetes mice, i.e., KK/TaJcl mice with Type-II diabetes and Streptozotocin-induced diabetes mice with Type-I diabetes, were used in this study. Particular attention was paid to uterine natural killer (uNK) cells and placental growth factor (PlGF). The number of fetuses, the fetal and placental weights in both diabetes mice were significantly decreased when compared to controls. Surprisingly, uNK cells in both diabetes mice persisted in the metrial gland even at the term of pregnancy. Although PlGF expression in both diabetes mice was significantly decreased, PlGF protein did not change. These results show that diabetes condition affects reproductive performance, particularly uNK cell behavior, but not PlGF production.
