Fig 2. Images of Beclin-1 staining in research groups.

Placental immunohistochemical staining for Beclin-1 in normal term pregnancy (A), late onset preeclampsia (B), early onset preeclampsia (C) and IUGR (D). Quantification was performed based on systematic random sampling. The point grid with 16 times 12 points placed on each image was used for systematic random quantification of staining There was stronger staining for Beclin-1 in late onset preeclampsia compared to normal term pregnancy, while there was no difference in staining intensity for Beclin-1 comparing early onset preeclampsia and IUGR. The strongest staining intensity was found in early onset preeclampsia. Original magnification x200.
