Fig. 2From: Effects of prostaglandin F2α (PGF2α) on cell-death pathways in the bovine corpus luteum (CL)Effect of local or systemic PGF2α analogue (aPGF2α) administration on the protein concentration of (a) caspase 3 (CASP3), (b) caspase 8 (CASP8) in the early- and middle- stage corpora lutea (CL), respectively. The gray bars represent the control group, and the black bars represent local or systemic aPGF2α administered groups. Letters a,b indicate statistical differences between all experimental groups in the early and middle- stage CL. Asteriks * indicate statistical differences between local/systemic aPGF2α injected early CL vs local/systemic aPGF2α injected middle-stage CLBack to article page
