Effect of bGH on blastocyst glucose transport. Blastocysts were incubated with 0–10,000 ng/ml (0–410 nM) bGH for 60 min, and then the uptake of 25 mM 3H-3-OMG was measured over 3 min at 37°C. Values represent the mean ± SEM of three experiments, each including 4–10 blastocysts per point. ∗∗, P < 0.01; ∗, P < 0.05 in comparison with 0 ng/ml bGH by ANOVA.
