Figure 6From: 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 tensionsTotal number of cells of Day 6 porcine blastocysts developed either under 5% or 20% oxygen tensions: comparison of different culture media during the first 2 days of IVC. Within each end point, bars with different letters (a, b) are significantly different for 5% oxygen tension treatment (P < 0.01). There were significant differences (P < 0.01) within each energy substrate supplement group (excepting the Gluc-20 group) across oxygen tension treatments. The numbers on the bars represent the number of embryos used for the assay.Back to article page
