FIG. 4.

Double GLUT2+/glucagon-positive cells in the pancreas of monkeys with recovered endogenous β-cell function. Co-expression is shown of glucose transporter GLUT2 with glucagon (A) and not with insulin (D) within islets damaged by STZ in M 4804 (monkey with recovered β-cell function). B and E: Nondiabetic monkey islet. C and F: STZ-diabetic monkey islet. Double GLUT2+/glucagon-positive and GLUT2+/proinsulin-positive cells stain in yellow. Lower panel: GLUT2/glucagon-positive cells in monkey M5204 (higher magnification). (Please see http://dx.doi.org/10.2337/db08-1127 for a high-quality digital representation of this figure.)
