Hourly averages of SK3^T/T mouse intrauterine pressure during delivery. Baseline intrauterine pressure (hourly average) increased above baseline in SK3^T/T uteri during delivery, but not to the same extent as that seen during WT delivery (WT data duplicated from Fig. 4). Baseline intrauterine pressure in SK3^T/T mice during delivery also was not gradually elevated as seen in WT mice during delivery. Values are means ± SE (WT n = 7, SK3 n = 4). *P < 0.001 vs. WT-cycle before delivery, †P < 0.05 vs. WT-cycle in which delivery occurred.
