Glucokinase, GLUT2, and IGF-I were measured by Western blotting in fetal pancreases in CON (n = 8) and INS (n = 8) groups. Western blottings are shown with densitometry quantification. There was significantly less (**, P < .01) glucokinase and more (*, P < .05) GLUT2 and IGF-I in INS pancreases. IGF-1, insulin like growth factor 1.
