Figure 4. Immunolocalization of iNOS in placental tissues.

Figure 4

Pregnant rats were injected with 0.5 ml of sControl or sStx2 (0.7 ng Stx2/g body wt) on day 15 of gestation and killed 12 h post injection. iNOS was detected in trophoblastic giant cells (A, black arrowhead) and glycogen cells (B; black arrowhead) of placentas from control rats. An increased label of iNOS in glycogen cells (C–D, black arrowhead) was observed in placentas from Stx2-treated rats. Original magnification: A and C ×200, B and D ×1000.
