Figure 3From: Development to the blastocyst stage, the oxidative state, and the quality of early developmental stage of porcine embryos cultured in alteration of glucose concentrations in vitro under different oxygen tensionsHydrogen peroxide levels in Day 1 (A) and Day 2 (B) porcine embryos cultured either in IVC medium containing 1.5 to 20 mM glucose or pyruvate-lactate. Values represent arbitrary fluorescence intensity units (FIU). Five replicate trials were carried out. Within each end point, bars with different letters (a-d and x-z) are significantly different for 5% and 20% oxygen tension treatments, respectively (P < 0.01). No significant differences were found in H2O2 levels within each energy substrate supplement group across oxygen tension treatments. The numbers on the bars represent the number of embryos used for the assay.Back to article page
