Immunolocalization of Bax, panel A and B; Bcl2, panel C and D; active caspase-9, panel E and F; active caspase-8, panel G and H; active caspase-3, panel I and J in placenta recovered from the control and PGN+poly(I:C) treated groups. Panel K and L are merged images (DAPI nuclear stain (blue), merged with FITC (stain for activated caspase-3)). Panels M, N, O and P show the immunostaining index score (ISIS) of Bax, Bcl2, active caspase-9 and active caspase-8 in placentas recovered from control and PGN+poly(I:C) treated groups. N=6 each group and six sections per animal were analyzed. Error bars= ±SEM. *P≤0.05 Significant difference vs respective control. Original magnification: 400X.
